Configuring Ethernet CFM
IP SLAs Support for CFM
The switch supports CFM with IP Service Level Agreements (SLAs), which provides the ability to
gather Ethernet layer network performance metrics. Available statistical measurements for the IP SLAs
CFM operation include round-trip time, jitter (interpacket delay variance), and packet loss. You can
schedule multiple IP SLAs operations and use Simple Network Management Protocol (SNMP) trap
notifications and syslog messages for proactive threshold violation monitoring.
For more information about IP SLAs, see
IP SLAs integration with CFM gathers Ethernet layer statistical measurements by sending and receiving
Ethernet data frames between CFM MEPs. Performance is measured between the source MEP and the
destination MEP. Unlike other IP SLAs operations that provide performance metrics for only the IP
layer, IP SLAs with CFM provides performance metrics for Layer 2.
You can manually configure individual Ethernet ping or jitter operations. You can also configure an IP
SLAs automatic Ethernet operation that queries the CFM database for all MEPs in a given maintenance
domain and VLAN. The operation then automatically creates individual Ethernet ping or jitter
operations based on the discovered MEPs.
For more information about IP SLAs operation with CFM, see the IP SLAs for Metro-Ethernet feature
module at this URL:

Configuring Ethernet CFM
Configuring Ethernet CFM requires configuring the CFM domain. You can optionally configure and
enable other CFM features such as crosschecking, remote MEP, port MEPs, SNMP traps, and fault
alarms.

Default Ethernet CFM Configuration
CFM is globally disabled.
CFM is enabled on all interfaces when CFM is globally enabled.
A port can be configured as a flow point (MIP/MEP), a transparent port, or disabled (CFM disabled). By
default, ports are transparent ports until configured as MEP, MIP, or disabled.
There are no MEPs or MIPs configured.
