Displaying Ethernet OAM Protocol Information
The router 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 router 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 15-4 to display Ethernet OAM protocol
information.
Enabling Ethernet Loopback
Service providers can use per-port and per VLAN Ethernet loopback to test connectivity at initial
startup, to test throughput, and to test quality of service (QoS) in both directions. The router supports
two types of loopback:
• Facility loopback allows per-port or per-port, per-VLAN loopback of traffic. It provides an alternate
method to Ethernet OAM remote loopback (see the “Enabling Ethernet OAM Remote Loopback”
section on page 15-36) to test connectivity across multiple switches. You can exchange (swap) MAC
destination and source addresses to allow a packet to cross multiple switches between the test head
and a test switch.
Step 8
ethernet oam link-monitor high threshold action
error-disable-interface
(Optional) Configure the router 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
show ethernet oam status [interface interface-id] Verify the configuration.
Step 14
copy running-config startup-config (Optional) Save your entries in the configuration file.
