The vRtrIgmpGeneralTable contains objects for general control and management of an IGMP protocol instance within a virtual router.

Each row entry represents an instance of the IGMP protocol running within a virtual router. Entries in this table cannot be created and deleted via SNMP SET operations. An entry in this table is created by the agent when vRtrIgmpStatus in the vRtrConfTable is set to 'create'. The entry is destroyed when vRtrIgmpStatus is set to 'delete'

vRtrIgmpGenQueryInterval is the frequency at which IGMP Host-Query packets are transmitted.

vRtrIgmpGenLastMembQueryIntvl is the Max Response Time inserted into Group-Specific Queries sent in response to Leave Group messages, and is also the amount of time between Group-Specific Query messages. This value may be tuned to modify the leave latency of the network. A reduced value results in reduced time to detect the loss of the last member of a group.

The maximum query response time advertised in IGMPv2 queries.

The Robustness Variable allows tuning for the expected packet loss on a subnet. If a subnet is expected to be lossy, the Robustness Variable may be increased. IGMP is robust to (Robustness Variable-1) packet losses.

An entry in this table can be created or destroyed by an SNMP SET request to vRtrIgmpIfRowStatus. An attempt to destroy a row will fail if vRtrIgmpIfAdminState has not first been set to 'outOfService'.

The activation of a row enables IGMP on the interface. The destruction of a row disables IGMP on the interface. Before this row can be destroyed, vRtrIgmpIfAdminState must have been set to 'outOfService'.

The sysUpTime when this row was last modified.

vRtrIgmpIfAdminState specifies the desired administrative state for IGMP protocol on this interface.

The current operational state of IGMP protocol on this interface.

The configured version of IGMP which is running on this interface. This object can be used to configure a router capable of running either value. For IGMP to function correctly, all routers on a LAN must be configured to run the same version of IGMP on that LAN.

The operational version of IGMP which is running on this interface. If the value of vRtrIgmpIfAdminVersion is configured as '3' but all of the routers in the local subnet of this interface use IGMP version v1 or v2, the operational version will be v1 or v2.

vRtrIgmpIfQuerierExpiryTime is the time remaining before vRtrIgmpIfQuerier is aged out. If vRtrIgmpIfQuerier is the local interface address, the value of vRtrIgmpIfQuerierExpiryTime will be zero.

If this router is the querier(vRtrIgmpIfQuerier is a local address), vRtrIgmpIfNextGenQueryTime is the time remaining before the general query is sent on this interface. If this router is not the querier on the interface, the value of this object will be zero.

vRtrIgmpIfSubnetCheck is used to enable/disable subnet checking for IGMP messages received on this interface. If this flag is set to 'true', subnet checking is enabled. All IGMP packets with a source address that is not in the local subnet are dropped.

The value of vRtrIgmpIfMaxGroups specifies the maximum number of groups for which IGMP can have local receiver information based on received IGMP reports on this interface. When this configuration is changed dynamically to a value lower than currently accepted number of groups, the groups that are already accepted are not deleted. Only new groups will not be allowed. When this object has a value of 0, there is no limit to the number of groups.

The value of vRtrIgmpIfMaxGroupsTillNow indicates the highest value that vRtrIgmpIfMaxGroups had till now.

The value of vRtrIgmpIfMcacPolicyName specifies the name of the multicast CAC policy. The multicast cac policy applies the interface cac algorithm if the channel(group) on this interface is part of the policy as specified in vRtrIgmpIfMcacPolicyName.

The value of vRtrIgmpIfMcacUnconstrainedBW specifies the bandwidth assigned for interface's multicast cac policy traffic in kilo-bits per second(kbps). If the default value of '-1' is set, there is no constraint on bandwidth allocated at the interface. If the value of vRtrIgmpIfMcacUnconstrainedBW is set to '0' and if a multicast cac policy is assigned on the interface, then no group (channel) from that policy is allowed on that interface.

The value of vRtrIgmpIfMcacConstAdminState specifies the administrative state of the multicast CAC policy's constraints.

The value of vRtrIgmpIfMcacPreRsvdMandBW specifies the bandwidth pre-reserved for all the mandatory channels on a given interface in kilo-bits per second(kbps). If the value of vRtrIgmpIfMcacUnconstrainedBW is '0', no mandatory channels are allowed. If the value of vRtrIgmpIfMcacUnconstrainedBW is '-1', then all mandatory and optional channels are allowed. If the value of vRtrIgmpIfMcacPreRsvdMandBW is equal to the value of vRtrIgmpIfMcacUnconstrainedBW, then all the unconstrained bandwidth on a given interface is allocated to mandatory channels configured through multicast cac policy on that interface and no optional groups (channels) are allowed. The value of vRtrIgmpIfMcacPreRsvdMandBW should always be less than or equal to that of vRtrIgmpIfMcacUnconstrainedBW. An attempt to set the value of vRtrIgmpIfMcacPreRsvdMandBW greater than that of vRtrIgmpIfMcacUnconstrainedBW will result in inconsistent value error.

The value of vRtrIgmpIfMcacinUseMandBw indicates the in-use bandwidth in kilo-bits per second(kbps) for the mandatory channels for this protocol interface instance.

If the value of vRtrIgmpIfMcacValuesInTransit is 'true' then the values are in transition.

vRtrIgmpIfDisRtrAlertChk is used to enable/disable router alert checking for IGMP messages received on this interface. If this flag is set to 'true', checking is disabled.

The value of vRtrIgmpIfMaxSources specifies the maximum number of sources for which IGMP can have local receiver information based on received IGMP reports on this interface. When this configuration is changed dynamically to a value lower than currently accepted number of sources, the sources that are already accepted are not deleted. Only new sources will not be allowed. When this object has a value of 0, there is no limit to the number of sources.

The table listing the IP multicast groups for which there are members on a particular interface. This table represents the IGMP group database.

An entry in the vRtrIgmpIfGroupTable. Each entry represents a group address for which receivers are interested/not interested in receiving multicast traffic.

The IP multicast group address for which this entry contains information.

vRtrIgmpIfGroupType indicates how this group entry was learned. If this group entry was learned by IGMP, it will be set to 'dynamic'. For statically configured groups, the value will be set to 'static'.

The time elapsed since this entry was created.

The minimum amount of time remaining before this entry will be aged out. A value of 0 indicates that the entry is only present because igmpCacheSelf is true and that if the router left the group, this entry would be aged out immediately. Note that some implementations may process membership reports from the local system in the same way as reports from other hosts, so a value of 0 is not required.

The time remaining until the local router will assume that there are no longer any IGMP version 1 members on the IP subnet attached to this interface. Upon hearing any IGMPv1 Membership Report, this value is reset to the group membership timer. While this time remaining is non-zero, the local router ignores any IGMPv2 Leave messages for this group that it receives on this interface.

vRtrIgmpIfGroupMode is based on the type of membership report(s) received on the interface for the group. In the 'include' mode, reception of packets sent to the specified multicast address is requested only from those IP source addresses listed in the source-list parameter of the IGMP membership report. In 'exclude' mode, reception of packets sent to the given multicast address is requested from all IP source addresses except those listed in the source-list parameter. vRtrIgmpIfGrpSrcTable lists the sources corresponding to this group, if any.

vRtrIgmpIfGroupCompatMode is used in order for routers to be compatible with older version routers. IGMPv3 hosts MUST operate in version 1 and version 2 compatibility modes. IGMPv3 hosts MUST keep state per local interface regarding the compatibility mode of each attached network. A host's compatibility mode is determined from the Host Compatibility Mode variable which can be in one of three states: IGMPv1, IGMPv2 or IGMPv3. This variable is kept per interface and is dependent on the version of General Queries heard on that interface as well as the Older Version Querier Present timers for the interface.

The time remaining until the local router will assume that there are no longer any IGMP version 2 members on the IP subnet attached to this interface. Upon hearing any IGMPv2 Membership Report, this value is reset to the group membership timer. While this time remaining is non-zero, the local router ignores any IGMPv3 Leave messages for this group that it receives on this interface.

The IP address of the source of the last membership report received for this IP Multicast group address on this interface. If no membership report has been received, this object has the value 0.0.0.0.

The table listing the IP multicast sources corresponding to the IP multicast groups for which there are members on a particular interface. This table represents IGMP source, group database.

An entry in the vRtrIgmpIfGrpSrcTable. Each entry represents a source address from which receivers are interested/not interested in receiving multicast traffic from.

The address of the source sending multicast traffic to the group identified by vRtrIgmpIfGroupAddress. If the value of vRtrIgmpIfGroupMode corresponding to this entry is 'include', the receivers are interested in receiving traffic from this source. If the value of vRtrIgmpIfGroupMode corresponding to this entry is 'exclude' and if the value of vRtrIgmpIfGrpSrcExpiryTime is '0', the receivers are not interested in receiving traffic from this source.

The minimum amount of time remaining before this entry will be aged out. If the value of vRtrIgmpIfGrpSrcExpiryTime is non-zero and the value of vRtrIgmpIfGroupMode corresponding to this entry is 'include', it means that there are currently one or more systems which desire to receive multicast traffic for this source. If this timer expires and the value of vRtrIgmpIfGroupMode is 'include', the router concludes that traffic from this particular source is no longer desired on the attached network, and deletes this entry. This timer is treated differently when the value of vRtrIgmpIfGroupMode is 'exclude'. If the value of vRtrIgmpIfGrpSrcExpiryTime is non-zero and router filter-mode for the group is 'exclude', it means that at least one system desires to receive multicast traffic from this source. It should therefore be forwarded by a router on the network.

vRtrIgmpIfGrpSrcType indicates how this source entry was learned. If this source entry was learned by IGMP, it will be set to 'dynamic'. For statically configured sources, the value will be set to 'static'.

The table listing the IP multicast sources corresponding to the IP multicast groups which are statically configured.

Each row entry in the vRtrIgmpGrpIfTable represents a group interface on this router that participates in the IGMP protocol. An entry in this table can be created or destroyed by an SNMP SET request to vRtrIgmpGrpIfRowStatus. An attempt to destroy a row will fail if vRtrIgmpGrpIfAdminState has not first been set to 'outOfService'.

The value of vRtrIfFwdSvcId specifies the forwarding service ID for a subscriber interface in a retailer context.

The activation of a row enables IGMP on the group interface. The destruction of a row disables IGMP on the group interface. Before this row can be destroyed, vRtrIgmpGrpIfAdminState must have been set to 'outOfService'.

The sysUpTime when this row was last modified.

vRtrIgmpGrpIfAdminState specifies the desired administrative state for IGMP protocol on this group interface.

The current operational state of IGMP protocol on this group interface.

vRtrIgmpGrpIfSubnetCheck is used to enable/disable subnet checking for IGMP messages received on SAPs belonging to this group-interface. If this flag is set to 'true', subnet checking is enabled. All IGMP packets with a source address that is not in the local subnet are dropped.

The value of vRtrIgmpGrpIfMcacPolicyName specifies the name of the multicast CAC policy. The multicast CAC policy applies to the group-interface CAC algorithm if the channel(group) on SAPs belonging to this group-interface is part of the policy as specified in vRtrIgmpGrpIfMcacPolicyName.

The value of vRtrIgmpGrpIfMcacUnconstrainedBW specifies the bandwidth assigned for all SAPs belonging to this group-interface's multicast CAC policy traffic in kilo-bits per second(kbps). If the default value of '-1' is set, there is no constraint on bandwidth allocated to the group-interface. If the value of vRtrIgmpGrpIfMcacUnconstrainedBW is set to '0' and if a multicast CAC policy is assigned on the group-interface, then no group (channel) from that policy is allowed on a SAP belonging to that group-interface.

The value of vRtrIgmpGrpIfMcacConstAdminState specifies the administrative state of the multicast CAC policy's constraints.

The value of vRtrIgmpGrpIfMcacPreRsvdMandBW specifies the bandwidth pre-reserved for all the mandatory channels on all SAPs belonging to a given group-interface in kilo-bits per second(kbps). If the value of vRtrIgmpGrpIfMcacUnconstrainedBW is '0', no mandatory channels are allowed. If the value of vRtrIgmpGrpIfMcacUnconstrainedBW is '-1', then all mandatory and optional channels are allowed. If the value of vRtrIgmpGrpIfMcacPreRsvdMandBW is equal to the value of vRtrIgmpGrpIfMcacUnconstrainedBW, then all the unconstrained bandwidth on all SAPs belonging to a given group-interface is allocated to mandatory channels configured through multicast CAC policy on that group-interface and no optional groups (channels) are allowed. The value of vRtrIgmpGrpIfMcacPreRsvdMandBW should always be less than or equal to that of vRtrIgmpGrpIfMcacUnconstrainedBW.

The vRtrGrpIfIndex value for each virtual interface must remain constant at least from one re-initialization of the system management processor to the next.

The IP multicast group address for which this entry contains information.

vRtrIgmpGrpIfHostGrpType indicates how this group entry was learned. If this group entry was learned by IGMP, it will be set to 'dynamic'. For statically configured groups, the value will be set to 'static'.

The time elapsed since this entry was created.

The minimum amount of time remaining before this entry will be aged out. A value of 0 indicates that the entry is only present because igmpCacheSelf is true and that if the router left the group, this entry would be aged out immediately. Note that some implementations may process membership reports from the local system in the same way as reports from other hosts, so a value of 0 is not required.

The time remaining until the local router will assume that there are no longer any IGMP version 1 members on the IP subnet attached to this host. Upon hearing any IGMPv1 Membership Report, this value is reset to the group membership timer. While this time remaining is non-zero, the local router ignores any IGMPv2 Leave messages for this group that it receives on this host.

vRtrIgmpGrpIfHostGrpMode is based on the type of membership report(s) received on the host for the group. In the 'include' mode, reception of packets sent to the specified multicast address is requested only from those IP source addresses listed in the source-list parameter of the IGMP membership report. In 'exclude' mode, reception of packets sent to the given multicast address is requested from all IP source addresses except those listed in the source-list parameter. vRtrIgmpGrpIfHostGrpSrcTable lists the sources corresponding to this group, if any.

vRtrIgmpGrpIfHostGrpCompatMode is used in order for routers to be compatible with older version routers. IGMPv3 hosts MUST operate in version 1 and version 2 compatibility modes. IGMPv3 hosts MUST keep state per local host regarding the compatibility mode of each attached network. A host's compatibility mode is determined from the Host Compatibility Mode variable which can be in one of three states: IGMPv1, IGMPv2 or IGMPv3. This variable is kept per interface and is dependent on the version of General Queries heard on that host as well as the Older Version Querier Present timers for the host.

The time remaining until the local router will assume that there are no longer any IGMP version 2 members on the IP subnet attached to this host. Upon hearing any IGMPv2 Membership Report, this value is reset to the group membership timer. While this time remaining is non-zero, the local router ignores any IGMPv3 Leave messages for this group that it receives on this host.

The address of the source sending multicast traffic to the group identified by tmnxSubIgmpHostGroupAddress.

The minimum amount of time remaining before this entry will be aged out. If the value of vRtrIgmpGrpIfHostGrpSrcExpTime is non-zero and the value of vRtrIgmpGrpIfHostGrpMode corresponding to this entry is 'include', it means that there are currently one or more systems which desire to receive multicast traffic for this source. If this timer expires and the value of vRtrIgmpGrpIfHostGrpMode is 'include', the router concludes that traffic from this particular source is no longer desired on the attached network, and deletes this entry. This timer is treated differently when the value of vRtrIgmpGrpIfHostGrpMode is 'exclude'. If the value of vRtrIgmpGrpIfHostGrpSrcExpTime is non-zero and router filter-mode for the group is 'exclude', it means that at least one system desires to receive multicast traffic from this source. It should therefore be forwarded by a router on the network.

vRtrIgmpGrpIfHostGrpSrcType indicates how this source entry was learned. If this source entry was learned by IGMP, it will be set to 'dynamic'. For statically configured sources, the value will be set to 'static'.

An entry in the vRtrIgmpHostGrpSrcTable. Each entry represents a source address from which receivers are interested/not interested in receiving multicast traffic from.

The minimum amount of time remaining before this entry will be aged out. If the value of vRtrIgmpHostGrpSrcExpiryTime is non-zero and the value of vRtrIgmpIfGroupMode corresponding to this entry is 'include', it means that there are currently one or more systems which desire to receive multicast traffic for this source. If this timer expires and the value of vRtrIgmpIfGroupMode is 'include', the router concludes that traffic from this particular source is no longer desired on the attached network, and deletes this entry. This timer is treated differently when the value of vRtrIgmpIfGroupMode is 'exclude'. If the value of vRtrIgmpHostGrpSrcExpiryTime is non-zero and router filter-mode for the group is 'exclude', it means that at least one system desires to receive multicast traffic from this source. It should therefore be forwarded by a router on the network.

vRtrIgmpHostGrpSrcType indicates how this source entry was learned. If this source entry was learned by IGMP, it will be set to 'dynamic'. For statically configured sources, the value will be set to 'static'.

A value of 0 indicates that the entry is only present because igmpCacheSelf is true and that if the router left the group, this entry would be aged out immediately. Note that some implementations may process membership reports from the local system in the same way as reports from other hosts, so a value of 0 is not required.

The time remaining until the local router will assume that there are no longer any IGMP version 1 members on the IP subnet attached to this host. Upon hearing any IGMPv1 Membership Report, this value is reset to the group membership timer. While this time remaining is non-zero, the local router ignores any IGMPv2 Leave messages for this group that it receives on this host.

vRtrIgmpHostGrpMode is based on the type of membership report(s) received on the host for the group. In the 'include' mode, reception of packets sent to the specified multicast address is requested only from those IP source addresses listed in the source-list parameter of the IGMP membership report. In 'exclude' mode, reception of packets sent to the given multicast address is requested from all IP source addresses except those listed in the source-list parameter. vRtrIgmpHostGrpSrcTable lists the sources corresponding to this group, if any.

The minimum amount of time remaining before this entry will be aged out. If the value of vRtrIgmpGrpIfSapGrpSrcExpTime is non-zero and the value of vRtrIgmpGrpIfSapGrpMode corresponding to this entry is 'include', it means that there are currently one or more systems which desire to receive multicast traffic for this source. If this timer expires and the value of vRtrIgmpGrpIfHostGrpMode is 'include', the router concludes that traffic from this particular source is no longer desired on the attached network, and deletes this entry. This timer is treated differently when the value of vRtrIgmpGrpIfSapGrpMode is 'exclude'. If the value of vRtrIgmpGrpIfSapGrpSrcExpTime is non-zero and router filter-mode for the group is 'exclude', it means that at least one system desires to receive multicast traffic from this source. It should therefore be forwarded by a router on the network.

A vRtrIgmpIfRxQueryVerMismatch notification is generated when the IGMP interface is configured as IGMPv3 but the router receives a IGMPv1 Query or IGMPv2 General Query on the interface. vRtrIfIndex will identify the router interface on which the query is received. vRtrIgmpIfAdminVersion will contain the configured version of the interface and vRtrIgmpNotifyQueryVersion will contain the version of the received query.

A vRtrIgmpIfCModeRxQueryMismatch notification is generated when there is a mismatch between the compatible mode of the interface and the version of the received query. It is generated when the IGMP interface is in IGMPv1 compatible mode but it receives a IGMPv2 or IGMPv3 Query on the interface. It is also generated when the compatibility mode of the interface is IGMPv2 but the query received is IGMPv3. vRtrIfIndex will identify the router interface on which the query is received. vRtrIgmpIfOperVersion will indicate the compatibility mode of the interface and vRtrIgmpNotifyQueryVersion will contain the version of the received query.

The vRtrIgmpMaxGrpsLimitExceeded event is generated when an attempt is made to configure a group when vRtrIgmpIfGroupCount, the number of groups configured on the PIM interface, is equal to vRtrIgmpIfMaxGroups, the maximum number of groups supported on the interface.

The vRtrIgmpMcacPlcyDropped event is generated when an IGMP group is dropped on a given interface because of applying a multicast CAC policy given by vRtrIgmpIfMcacPolicyName.

The vRtrIgmpHostInstantiationFail event is generated when a host is eligible for running IGMP, but IGMP cannot be started on the host.

The vRtrIgmpMaxGrpsLimitExceeded event is generated when an attempt is made to configure a group when vRtrIgmpHostGroupCount, the number of groups configured on the PIM interface, is equal to vRtrIgmpHostMaxGroups, the maximum number of groups supported on the host.

The vRtrIgmpHostMcacPlcyDropped event is generated when an IGMP group is dropped on a given Host because of applying a multicast CAC policy given by vRtrIgmpNotifyMcacPolicyName.

A vRtrIgmpHostCModeRxQueryMismatch notification is generated when there is a mismatch between the compatible mode of the IGMP Host and the version of the received query. It is generated when the Host is in IGMPv1 compatible mode but it receives a IGMPv2 or IGMPv3 Query. It is also generated when the compatibility mode of the Host is IGMPv2 but the query received is IGMPv3. vRtrIgmpHostAddress will identify the Host on which the query is received. vRtrIgmpHostOperVersion will indicate the compatibility mode of the Host and vRtrIgmpNotifyQueryVersion will contain the version of the received query.

A vRtrIgmpHostRxQueryVerMismatch notification is generated when the IGMP host is configured as IGMPv3 but receives a IGMPv1 Query or IGMPv2 General Query on the host. vRtrIgmpHostAddress will identify the Host on which the query is received. vRtrIgmpHostAdminVersion will contain the configured version of the Host and vRtrIgmpNotifyQueryVersion will contain the version of the received query.

The vRtrIgmpHostMaxSrcsLimitExceeded event is generated when an attempt is made to configure a source for a group when the number of sources for this group is equal to vRtrIgmpHostMaxSources, the maximum number of sources per group supported on the host.

The vRtrIgmpMaxSrcsLimitExceeded event is generated when an attempt is made to configure a source for a group when the number of sources for this group is equal to vRtrIgmpIfMaxSources, the maximum number of sources per group supported on the interface.

The vRtrIgmpGrpIfSapMaxGrpsLimExceed event is generated when an attempt is made to configure a group when vRtrIgmpGrpIfSapGroupCount, the number of groups configured on the SAP, is equal to vRtrIgmpGrpIfSapMaxGroups, the maximum number of groups supported on the SAP.

The vRtrIgmpGrpIfSapMaxSrcsLimExceed event is generated when an attempt is made to configure a source for a group when the number of sources for this group is equal to vRtrIgmpGrpIfSapMaxSources, the maximum number of sources per group supported on the SAP.

The vRtrIgmpGrpIfSapMcacPlcyDropped event is generated when an IGMP group is dropped on a given SAP because of applying a multicast CAC policy given by vRtrIgmpNotifyMcacPolicyName.

A vRtrIgmpGrpIfSapCModeRxQueryMism notification is generated when there is a mismatch between the compatible mode of the IGMP SAP and the version of the received query. It is generated when the SAP is in IGMPv1 compatible mode but it receives a IGMPv2 or IGMPv3 Query. It is also generated when the compatibility mode of the SAP is IGMPv2 but the query received is IGMPv3. sapPortId and sapEncapValue will identify the SAP on which the query is received. vRtrIgmpGrpIfSapOperVersion will indicate the compatibility mode of the SAP and vRtrIgmpNotifyQueryVersion will contain the version of the received query.

A vRtrIgmpGrpIfSapRxQueryVerMism notification is generated when the IGMP host SAP is configured as IGMPv3 but receives a IGMPv1 Query or IGMPv2 General Query on the host. sapPortId and sapEncapValue will identify the SAP on which the query is received. vRtrIgmpGrpIfSapAdminVersion will contain the configured version of the SAP and vRtrIgmpNotifyQueryVersion will contain the version of the received query.
