Chapter Configuring Ethernet Virtual Connection Bridge Domain

Connectivity Fault Management (CFM) over EVC BD

IEEE CFM is an end-to-end per-service Ethernet-layer Operations, Administration, and Maintenance

(OAM) protocol. CFM includes proactive connectivity monitoring, fault verification, and fault isolation

for large Ethernet metropolitan-area networks (MANs) and WANs.

CFM over EVC BD (Up mep) and CFM over EVC BD (Down mep) features are supported on CFM over

EVC BD.

CFM over Xconnect (Up mep) and CFM over Xconnect (Down mep) features are not supported on CFM

over EVC BD.

The benefits of Ethernet CFM are:

• End-to-end service-level OAM technology

• Reduced operating expense for service provider Ethernet networks

• Competitive advantage for service providers

Note This feature is supported only if you have purchased the appxk9 licensing package. CFM over EVC BD

is available only on the Cisco 890 series ISR and ISRG2 platforms. For more information about

managing software activation licenses on the Cisco ISR and Cisco ISR G2 platforms, see

http://www.cisco.com/en/US/docs/routers/access/sw_activation/SA_on_ISR.html.

Restrictions for Configuring Ethernet CFM

• A specific domain must be configured. If it is not, an error message is displayed.

• Multiple domains (different domain names) having the same maintenance level can be configured.

However, associating a single domain name with multiple maintenance levels is not permitted.
