Description: Provides management objects for configuring and monitoring Ethernet Virtual Circuits (EVCs) on Cisco carrier Ethernet devices.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is CISCO-EVC-MIB?

CISCO-EVC-MIB is a Cisco enterprise MIB that manages Ethernet Virtual Connections (EVCs), as defined by the Metro Ethernet Forum, on Cisco carrier/Metro Ethernet switching platforms. It exposes configuration and status data for EVC-capable ports, user-network interfaces (UNIs), and service instances, including per-port EVC/service-instance limits, MAC address learning limits, and violation causes. Administrators use it to monitor the software-level state of the Ethernet service layer -- how many EVCs and service instances are configured versus the platform maximum, current MAC address usage against configured limits, and the specific cause when a MAC-limit or service violation occurs -- surfacing capacity exhaustion or misconfiguration before it becomes service-affecting. It builds on standard Ethernet/interface MIBs (IF-MIB) since EVCs and UNIs are layered over physical/logical Ethernet ports. It is typically deployed on Cisco Metro Ethernet switches and routers delivering carrier Ethernet services to business and service-provider customers. Engineers can download the CISCO-EVC-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-EVC-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Cisco Metro/Carrier Ethernet switch or router

Monitoring Examples

An operator would compare cevcNumCfgEvcs against cevcMaxNumEvcs to see how close a chassis is to its EVC capacity limit, and poll cevcPortTable/cevcPortEntry for cevcPortMaxNumEVCs and cevcPortMaxNumServiceInstances per port to catch a port nearing its service-instance ceiling. Checking cevcViolationCause alongside cevcMaxMacConfigLimit and cevcMacAddress would reveal whether a recent violation was due to exceeding the configured MAC address limit on a UNI. Walking cevcUniTable helps confirm which physical ports are enabled as user-network interfaces for EVC service delivery.

What Can Be Monitored

configured vs. maximum EVC count
per-port EVC and service-instance limits
MAC address learning limit and usage
EVC/service violation cause
UNI port configuration

The bridge domain range is 1~16k, this object is to track the base of each 4k bitmap. cevcSIForwardBdNumber1kBitmap indicates a string of octets containing one bit per Bridge domain per service instance. This 128-octet bitmap represents bridge domain ID values 0~1023. cevcSIForwardBdNumber2kBitmap indicates a string of octets containing one bit per Bridge domain per service instance. This 128-octet bitmap represents bridge domain ID values 1024~2047. cevcSIForwardBdNumber3kBitmap indicates a string of octets containing one bit per Bridge domain per service instance. This 128-octet bitmap represents bridge domain ID values 2048~3071. cevcSIForwardBdNumber4kBitmap indicates a string of octets containing one bit per Bridge domain per service instance.

The system automatically creates an entry for each ifEntry in the ifTable having an ifType of 'ethernetCsmacd' capable of supporting Ethernet services and entries are automatically destroyed when the corresponding row in the ifTable is destroyed.
cevcPortGroup	1.3.6.1.4.1.9.9.613.2.2.2			A collection of objects providing configuration for ports in an EVC.
INT cevcPortL2ControlProtocolAction	1.3.6.1.4.1.9.9.613.1.2.3.1.2	INTEGER	read-create	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.

The value of '0' this column indicates that the service instance is not associated to an EVC. If the value of cevcSIEvcIndex column is not '0', there must exist an active row in the cevcEvcTable with the same index value for cevcEvcIndex.
cevcSIForwardBdEntry	1.3.6.1.4.1.9.9.613.1.4.10.1		not-accessible	This entry represents an bridged domain used to forward service frames by the service instance. Entries in this table may be created and deleted via the cevcSIForwardBdRowStatus object or the management console on the system. Using SNMP, rows are created by a SET request setting the value of the cevcSIForwardBdRowStatus column to 'createAndGo' or 'createAndWait'.

U32 cevcSIForwardBdNumber	1.3.6.1.4.1.9.9.613.1.4.10.1.3	Unsigned32	read-create	The bridge domain identifier that is associated with the service instance. A bridge domain refers to a layer 2 broadcast domain spanning a set of physical or virtual ports. Frames are switched Multicast and unknown destination unicast frames are flooded within the confines of the bridge domain.
OCT cevcSIForwardBdNumber1kBitmap	1.3.6.1.4.1.9.9.613.1.4.10.1.5	OCTET STRING	read-create	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.
OCT cevcSIForwardBdNumber2kBitmap	1.3.6.1.4.1.9.9.613.1.4.10.1.6	OCTET STRING	read-create	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 1024 through 1031; the second octet to Bridge domains 1032 through 1039; etc. Thus, this 128-octet bitmap represents bridge domain ID value 1024~2047. 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.

ciscoEvcMIB	1.3.6.1.4.1.9.9.613			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'. CE MEN MEN CE ------- ------- ------- ------- \| \| \| \| () \| \| \| \| \| \|--------Ux x\|--( )--\|x xU--------\| \| \| \| \| \| () \| \| \| \| ------- ------- ------- ------- ^ ^ \| \| -------- EVC --------- This MIB module addresses the functional areas of network management for EVC, including: The operational mode for interfaces that are providing Ethernet service(s). The service attributes regarding an interface behaving as UNI, such as CE-VLAN mapping and layer 2 control protocol (eg. stp, vtp, cdp) processing. The provisioning of service instances to define flow points for an Ethernet service. The operational status of EVCs for notifications of status changes, and EVC creation and deletion.
