Chapter 41 Configuring Ethernet OAM, CFM, and E-LMI
Displaying Ethernet OAM Protocol Information
The switch does not support monitoring egress frames with CRC errors. The

command is visible on the switch and you can enter it, but it is not supported. Use the
no
form of each
command to remove the option from the template. Use the
no source-template
template-name
to remove
the source template association.
Displaying Ethernet OAM Protocol Information
You can use the privileged EXEC commands in
Table 41-3
to display Ethernet OAM protocol
information.
Understanding E-LMI
Ethernet Local Management Interface (E-LMI) is a protocol between the customer-edge (CE) device and
the provider-edge (PE) device. It runs only on the PE-to-CE UNI link and notifies the CE device of
connectivity status and configuration parameters of Ethernet services available on the CE port. E-LMI
interoperates with an OAM protocol, such as CFM, that runs within the provider network to collect OAM
status. CFM runs at the provider maintenance level (UPE to UPE with inward-facing MEPs at the UNI).
E-LMI relies on the OAM Ethernet Infrastructure to interwork with CFM for end-to-end status of
Ethernet virtual connections (EVCs) across CFM domains.
Step 8
ethernet oam link-monitor high
threshold action
error-disable-interface
(Optional) Configure the switch to put an interface in an
error disabled state when a high threshold for an error is
exceeded.
Step 9
exit
Return to global configuration mode.
Step 10
interface
interface-id
Define an Ethernet OAM interface, and enter interface
configuration mode.
Step 11
source-template
template-name
Associate the template to apply the configured options to
the interface.
Step 12
end
Return to privileged EXEC mode.
Step 13
