The switch does not support monitoring egress frames with CRC errors. The ethernet oam link-monitor
transmit-crc {threshold {high {high-frames | none} | low {low-frames}} | window milliseconds}
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.

You can use the privileged EXEC commands in
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 up MEPs at the UNI).

Purpose
(Optional) Configure the switch to put an interface in an
error disabled state when a high threshold for an error is
exceeded.
Return to global configuration mode.
Define an Ethernet OAM interface, and enter interface
configuration mode.
Associate the template to apply the configured options to
the interface.
Return to privileged EXEC mode.
Verify the configuration.
(Optional) Save your entries in the configuration file.
