CISCO-EVC-MIB: View SNMP OID List / Download MIB

Metro Ethernet services can support a wide range of applications and subscriber needs easily, efficiently and cost-effectively. Using standard Ethernet interfaces, subscribers can set up secure, private Ethernet Virtual Connections, to connect their sites together and connect to business partners, suppliers and the Internet. This MIB module defines the managed objects and notifications describing Ethernet Virtual Connections. Ethernet Virtual Connections (EVC), are defined by the Metro Ethernet Forum (MEF), as an association between two or more UNIs. Frames within an EVC can only be exchanged among the associated UNIs. Frames sent into the MEN via a particular UNI must not be delivered back to the UNI from which it originated. Along an EVC path, there are demarcation flow points on associated ingress and egress interface, of every device, through which the EVC passes. A service instance represents these flow points where a service passes through an interface. From an operational perspective, a service instance serves three purposes: 1. Defines the instance of a particular EVC service on a specific interface and identifies all frames that belongs to that particular service/flow. 2. To provide the capability of applying the configured features to those frames belonging to the service. 3. To optionally define how to forward those frames in the data-path. The association of a service instance to an EVC depicts an instance of an Ethernet flow on a particular interface for an end-to-end (UNI-to-UNI) Ethernet service for a subscriber. The following diagram illustrates the association of EVC, UNIs and service instances. UNI physical ports are depicted as 'U', and service instances as 'x'.

This table contains a list of UNIs locally configured on the system. This table has a sparse dependent relationship on the cevcPortTable, containing a row for each cevcPortEntry having a cevcPortMode column value 'uni'.

This entry represents an UNI and its service attributes. The system automatically creates an entry when the system or the EMS/NMS creates a row in the cevcPortTable with a cevcPortMode of 'uni'. Likewise, the system automatically destroys an entry when the system or the EMS/NMS destroys the corresponding row in the cevcPortTable.

This object specifies a string-value assigned to a UNI for identification. When the UNI identifier is configured by the system or the EMS/NMS, it should be unique among all UNIs for the MEN. If the UNI identifier value is not specified, the value of the cevcUniIdentifier column is a zero-length string.

This object specifies the UNI port type. 'dot1q' The UNI port is an IEEE 802.1q port. 'dot1ad' The UNI port is an IEEE 802.1ad port. Enumeration: 'dot1ad': 2, 'dot1q': 1.

This object specifies the UNI service attributes. 'serviceMultiplexing' This bit specifies whether the UNI supports multiple EVCs. Point-to-Point EVCs and Multipoint-to-Multipoint EVCs may be multiplexed in any combination at the UNI if this bit is set to '1'. 'bundling' This bit specifies whether the UNI has the bundling attribute configured. If this bit is set to '1', more than one CE-VLAN ID can map to a particular EVC at the UNI. 'allToOneBundling' This bit specifies whether the UNI has the all to one bundling attribute. If this bit is set to '1', all CE-VLAN IDs map to a single EVC at the UNI. To summarize the valid combinations of serviceMultiplexing(0), bundling(1) and allToOneBundling(2) bits for an UNI, consider the following diagram: VALID COMBINATIONS +---------------+-------+-------+-------+-------+-------+ |UNI ATTRIBUTES | 1 | 2 | 3 | 4 | 5 | +---------------+-------+------+------------------------+ |Service | | | | | | |Multiplexing | | Y | Y | | | | | | | | | | +---------------+-------+-------+-------+-------+-------+ | | | | | | | |Bundling | | | Y | Y | | | | | | | | | +---------------+-------+-------+-------+-------+-------+ |All to One | | | | | | |Bundling | | | | | Y | | | | | | | | +---------------+-------+-------+------ +-------+-------+ Bits: 'bundling': 1, 'serviceMultiplexing': 0, 'allToOneBundling': 2.

This table lists the layer 2 control protocol processing attributes at UNI ports. This table has an expansion dependent relationship on the cevcUniTable, containing zero or more rows for each UNI.

This entry represents the layer 2 control protocol processing at the UNI. The system automatically creates an entry for each layer 2 control protocol type when an entry is created in the cevcUniTable, and entries are automatically destroyed when the system destroys the corresponding row in the cevcUniTable.

This object indicates the type of layer 2 control protocol service frame as denoted by the value of cevcPortL2ControlProtocolAction column.

This object specifies the action to be taken for the given layer 2 control protocol service frames which matches the cevcPortL2ControlProtocolType, including: 'discard' The port must discard all ingress service frames carrying the layer 2 control protocol service frames and the port must not generate any egress service frames carrying the layer 2 control protocol service frames. When this action is set at the port, an EVC cannot process the layer 2 control protocol service frames. 'peer' The port must act as a peer, meaning it actively participates with the Customer Equipment, in the operation of the layer 2 control protocol service frames. An example of this is port authentication service at the UNI with 802.1x or enhanced link OAM functionality by peering at the UNI with link OAM (IEEE 802.3ah). When this action is set at the port, an EVC cannot process the layer 2 control protocol service frames. 'passToEvc' The disposition of the service frames which are layer 2 control protocol service frames must be determined by the layer 2 control protocol action attribute of the EVC, (see cevcSIL2ControlProtocolAction for further details). 'peerAndPassToEvc' The layer 2 control protocol service frames will be peered at the port and also passed to one or more EVCs for tunneling. An example of this possibility is where an 802.1x authentication frame is peered at the UNI for UNI-based authentication, but also passed to a given EVC for customer end-to-end authentication. Enumeration: 'peer': 2, 'discard': 1, 'peerAndPassToEvc': 4, 'passToEvc': 3.

This table contains for each UNI, a list of EVCs and the association of CE-VLANs to the EVC. The CE-VLAN mapping is locally significant to the UNI. This table has an expansion dependent relationship on the cevcUniTable, containing zero or more rows for each UNI.

For local UNIs, the UNI Id is the same as denoted by cevcUniIdentifier with the same ifIndex value as cevcEvcLocalUniIfIndex. For remote UNIs, the underlying OAM protocol, if capable, provides the UNI Id via its protocol messages. This table has an expansion dependent relationship on the cevcEvcTable, containing a row for each UNI that is in the EVC.

This entry represents a UNI, either local or remote, in the EVC. The system automatically creates an entry, when an UNI is attached to the EVC. Entries are automatically destroyed when the system or the EMS/NMS destroys the corresponding row in the cevcEvcTable or when an UNI is removed from the EVC.

This object indicates an arbitrary integer-value that uniquely identifies the UNI in an EVC.

This object indicates the string-value identifying the UNI that is in the EVC. For UNI that is local, this value is the same as cevcUniIdentifier for the same ifIndex value as cevcEvcLocalUniIfIndex.

This object specifies a string of octets containing one bit per Bridge domain per service instance(generally we have one bridge domain per nontrunk service instance but can have more than one bridge configured with a trunk service instance). The first octet corresponds to Bridge domains with Bridge domain ID values of 0 through 7; the second octet to Bridge domains 8 through 15; etc. Thus, this 128-octet bitmap represents bridge domain ID value 0~1023. For each Bridge domain configured, the bit corresponding to that bridge domain is set to '1'. SNMP Administrator uses cevcSIForwardBdNumberBase + (position of the set bit in bitmap)to calculate BD number of a service instance. Note that if the length of this string is less than 128 octets, any 'missing' octets are assumed to contain the value zero. An NMS may omit any zero-valued octets from the end of this string in order to reduce SetPDU size, and the agent may also omit zero-valued trailing octets, to reduce the size of GetResponse PDUs.

This object specifies a string of octets containing one bit per Bridge domain per service instance(generally we have one bridge domain per nontrunk service instance but can have more than one bridge configured with a trunk service instance).

For each Bridge domain configured, the bit corresponding to that bridge domain is set to 1. SNMP Administrator uses cevcSIForwardBdNumberBase + (position of the set bit in bitmap)to calculate BD number of a service instance. Note that if the length of this string is less than 128 octets, any 'missing' octets are assumed to contain the value zero.

For each Bridge domain configured, the bit corresponding to that bridge domain is set to 1. SNMP Administrator uses cevcSIForwardBdNumberBase + (position of the set bit in bitmap)to calculate BD number of a service instance. Note that if the length of this string is less than 128 octets, any 'missing' octets are assumed to contain the value zero. An NMS may omit any zero-valued octets from the end of this string in order to reduce SetPDU size, and the agent may also omit zero-valued trailing octets, to reduce the size of GetResponse PDUs.

This object specifies a string of octets containing one bit per Bridge domain per service instance(generally we have one bridge domain per non-trunk service instance but can have more than one bridge configured with a trunk service instance).
