MIB for the Channel Manager. The Channel Manager is a function that manages connections and their channels in a consistent manner, independently of the service that uses the connection. The Channel Manager provides a common method to configure the connections, and to present data about the connections and channels that exist.

Time stamp when any data in any of the tables in this group were last updated.

Descriptions on originating connections. The creation and deletion of rows in the table is done by the application that provides the service on the connection. When a row is deleted, the associated rows in the destination table chmgrODescrDestinationTable and channel table chmgrODescrChannelTable are also deleted. The table contains information about the capabilities of the connections as well as the actual configuration of the connections. As the capabilities depends on the type of service, it is the service's application that is responsible for defining these. Changes made on a row in the table will take immediate effect. This could result in a re-establishment of the channel(s) using the new parameters.

An entry in the table is representing the description and configuration of one connection.

Index for this entry.

This is the unique connection type identifier that defined the type of service that the connection description describes. ets(1). Ethernet Transport Service (DTM LAN Transport). its(2). Isochronous Transport Service (DTM Isochronous Transport). dle(3). DTM LAN Emulation. Enumeration: 'ets': 1, 'its': 2, 'dle': 3.

Connection capabilities that indicate which parameters that are possible to configure in this connection description. allowCapacityInterval(0) Allows the configuration of capacity to have different values on requested and accepted capacity. destination(1) Describes if destinations shall be configured for this description. This is the normal case for most connections, but is some cases, the destination is decided by the application that is responsible for the service on the connection. allowDynamicCapacity(2) Allows the use of dynamic capacity adjustment. isMulticast(3) Describes if the connection is a multicast connection. This value is set by the application that is responsible for the service that uses the connection. allowEstablish(4) Allows the configuration of whether the connection shall be established using the capacity configurations of the connection or not. allowProtection(5) Allows the connection to be configured to be 1+1 protected by using two channels for the connection. allowReestablish(6) Allows configuration of the re- establishment algorithm. allowScheduling(7) Allows an external application, such as a scheduled, to alter the capacity and administrative state of the connection. allowSourceRoute(8) Allows configuration of source routed connections. requireCapacity(9) Requires the configuration of capacity. This is the normal case for most connections, but in some cases, the capacity is defaulted by the application. allowAlternative(10) Allows configuration of several alternative destinations. The unicast connection will be established using only one of the available destination. allowZeroCapacity(11). Allows configuration of zero capacity. Bits: 'allowZeroCapacity': 11, 'allowAlternative': 10, 'isMulticast': 3, 'destination': 1, 'allowDynamicCapacity': 2, 'allowScheduling': 7, 'allowSourceRoute': 8, 'allowProtection': 5, 'allowReestablish': 6, 'allowCapacityInterval': 0, 'allowEstablish': 4, 'requireCapacity': 9.

This is a customer identifications number assigned by the application that is providing the service on the connection. The object has no functional use except to provide the information.

This is a pointer to the application or service that owns this connection description, and that is responsible for the capabilities.

The minimum payload capacity in bits per second for the service using the channel. If it is not possible to allocate this capacity, a channel will not be established. If the acceptable capacity is larger than the maximum value (4,294,967,295) bits per second, then the `chmgrODescrAcceptableMbps' must be used. If the capacity is greater than the maximum value of this object, then the this object should report the maximum value.

The minimum capacity in number of 512 kbps DTM slots. The value is based on the chmgrAcceptableBps and the necessary overhead required by the service for delivering the payload capacity. The overhead is calculated by the service application.

The requested payload capacity in bits per second for the service using the channel. If the requested capacity is larger than the maximum value (4,294,967,295) bits per second, then the `chmgrODescrRequestedMbps' must be used. If the capacity is greater than the maximum value of this object, then the this object should report the maximum value.

The requested capacity in number of 512 kbps DTM slots. The value is based on the chmgrRequestedBps and the necessary overhead required by the service for delivering the payload capacity. The overhead is calculated by the service application.

The type of algorithm or method used to re-establish channels that for some reason fail to be established or is torn down. The methods are: exponential(1) Establishment attempts are done at time interval that is doubled for each attempt, starting at chmgrMinInterval and increased to a maximum of chmgrMaxInterval, until a channel is successfully established. The value is only valid if the allowReestablish(6) bit in chmgrODescrCapabililties is set. Enumeration: 'exponential': 1.

The minimum time in milliseconds between two attempts to establish the channel.

The maximum time in milliseconds between two attempts to establish the channel. This value must be larger than chmgrODescrMinInterval.

Describes if the connection shall be established with the defined parameters. The value is only valid if the allowEstablish(4) bit in chmgrODescrCapabilites is set. true(1) The connection is established. false(2) The connection is not established. The establishment of the connection is controlled by some other function outside the scope of this MIB. This could be a scheduler or timer specified in other MIB's.

The value of the next available index for this connection description in the chmgrODescrDestinationTable.

A channel with precedence is established and torn down before any channel without precedence. true(1) The channel has precedence. false(2) The channel does not have precedence.

Suppress generation of some alarms: route(0) Alarm raised if a service is not using its primary source route. Bits: 'route': 0.

The minimum payload capacity in units of 1,000,000 bits per second for the service using the channel. If it is not possible to allocate this capacity, a channel will not be established. This object must be used when requesting a capacity larger than 4,294,967,295 bits per second. If a lower capacity is requested, then it is possible to use `chmgrODescrAcceptableBps'.

The requested payload capacity in units of 1,000,000 bits per second for the service using the channel. This object must be used when requesting a capacity larger than 4,294,967,295 bits per second. If a lower capacity is requested, then it is possible to use `chmgrODescrRequestedBps'.

The DCP version that should be used for channel established for this connection. `any' means try with DCP3 first and revert to DCP2 if unsuccessful because of node version mismatch.

Specifies if the the channel shall dynamically allocate spare capacity. When `true', then the channel is initially established with the acceptable capacity specified in chmgrODescrAcceptableBps (or chmgrODescrAcceptableMbps). The channel capacity is then monitored and automatically increased with available capacity up to the capacity specified in chmgrODescrRequestedBps (or chmgrODescrRequestedMbps). If another channel would request capacity, then the capacity of this channel is reduced as needed by the other channel, but not below the acceptable capacity. When set to `false', then spare capacity will not be used. This function requires use of DCP3, see chmgrODescrRequestedDcpVersion. This function requires use of ETS unicast. This function requires the channel destination to be a neighboring node.

The table describes destinations for a connection. A unicast connection can normally only have one destination, while a multicast connection may have several destinations. If a unicast connection allows alternative destinations, as defined by the allowAlternative(10) bit in chmgrODescrCapabilities, it is allowed to define multiple destinations. At channel establishment, the destinations will be tried in succession until a channel is successfully established. It is possible to add, change and delete destinations while the connection is active. For a unicast connection, a changed destination is torn down as soon as it is changed, and established as soon as the changed information contains valid data. For a multicast connection, it is possible to add and delete destinations to an already established connection without affecting the connection to the other destinations. An added destination will be established as soon as it includes valid information, and will be re-established as soon as the information is changed. Note that a destination address with an empty string can be used to disable the destination. For a multicast connection a single destination can also be enabled and disabled using its administrative status. The bits allowAlternative(10), destination(1) and allowMulticast(3) in chmgrODescCapabilities describes if and how it is allowed to add a destination to a connection.

An entry in the table represents one destination.

The index for this entry.

See SNMPv2-TC. The following values are supported: active(1) The object always reads active(1). createAndGo(4) A new conceptual row is created representing a new destination. destroy(6) The conceptual row representing the destination is deleted, and the connection to the destination is torn down. Connections to other destinations are not affected. Associated rows in the channel table chmgrODescrChannelTable will also be destroyed.

The administrative state of the destination. The value controls the desired state of the multicast connection to the destination. up(1). The connection shall be established to the destination. down(2). No connection shall be established to the destination. Enumeration: 'down': 2, 'up': 1.

The table describes relationships between destinations defined in the chmgrODescrDestinationTable, channels and source routes. To make a connection to a destination 1+1 protected, create two rows representing the two channels in the table. Note that this is only allowed if the bit allowProtection(5) is set in chmgrODescrCapabilities. If no conceptual row exists for a destination, it is assumed that there shall be only one channel to the destination and that no source route is shall be used. A channel to a destination may have its route through the DTM networks defined by one or many source routes. If multiple source routes are defined, any one of these source routes is chosen when the channel is established.

An entry in this table represents the relationship between one channel in the connection (defined in chmgrODescrDestinationTable) and one source route (defined in chmgrSourceRouteTable).

Table listing source routes. A source route is a route through the DTM net that is defined at the source of the channel. The source routes may be used by many connections, making the connections using the same route through the DTM network. A source route may only be updated or deleted when it is not used by any established connection. Note that a source route set up as loose, with no intermediate nodes, and set up to use any outgoing interface is equivalent to a shortest path routing.

An entry representing one source route.

The index for this entry.

A string for administrative use that identifies or describes the source route. The string does not have to be unique.

Information about the administrative state of the connection. The administrative state is controlled by the application that provides the service transported on the connection. The application sets the administrative state to up(1) when a connection shall be established, and down(2) when the connection shall be torn down. Enumeration: 'down': 2, 'up': 1.

The operational state of the connection. In general, the operational state should follow the administrative state, chmgrOConnAdminStatus. up(1) The connection is up to all its destination on all its channels. For a unicast connection, this is the one configured destination. For a multicast connection, this is all the configured connections. For a 1+1 protected connection, this is both the channels. down(2) No channels are established for the connection. partial(3) The connection is partly established. The connection is not established to at least one of its configured destination on at least one of its channels. dormant(5) The establishment of the connection is pending an action from some other entity, e.g. a scheduler. This is not an error state. Enumeration: 'down': 2, 'dormant': 5, 'partial': 3, 'up': 1.

Writing to this object immediately starts to re-establish the connection to all its destinations. The establishment of the connection will be done according to the current network topology and availability. If source routes are defined, the first source route will be tried first. notApplicable(0) Always reads this value. This value cannot be written. reestablish(1) Writing this value reestablishes the connection. Enumeration: 'notApplicable': 0, 'reestablish': 1.

Writing to this object immediately starts to re-establish the connection to the destinations and channels using the source route specified with the written value. The value written controls which source route to first try when re-establishing the channel. For each destination and channel for the connection, the written value is used as value for the index chmgrODescrChanSourceRouteIndex in the the chmgrODescrChannelTable. If the entry does not exist, or if the source route is already the one that used by the destination and channel, then no action is taken. Otherwise if the entry exists, then the channel for the destination is re-established, where the given source route is first attempted. Reading this always returns the value 0.
