Setting Up and Configuring Ethernet OAM
Ethernet OAM Configuration Guidelines
Follow these guidelines when configuring Ethernet OAM:
• The router does not support monitoring of egress frames sent with cyclic redundancy code (CDC)
errors. The ethernet oam link-monitor transmit crc interface-configuration or
template-configuration commands are visible but are not supported on the router. The commands
are accepted, but are not applied to an interface.
• For a remote failure indication, the router does not generate Link Fault or Critical Event OAM
PDUs. However, if these PDUs are received from a link partner, they are processed. The router
supports generating and receiving Dying Gasp OAM PDUs when Ethernet OAM is disabled, the
interface is shut down, the interface enters the error-disabled state, or the router is reloading. It can
respond to, but not generate, Dying Gasp PDUs based on loss of power.
Enabling Ethernet OAM on an Interface
Beginning in privileged EXEC mode, follow these steps to enable Ethernet OAM on an interface:
Enter the no ethernet oam interface configuration command to disable Ethernet OAM on the interface.
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
interface interface-id Define an interface to configure as an EOM interface, and
enter interface configuration mode.
Step 3
ethernet oam Enable Ethernet OAM on the interface.
Step 4
ethernet oam [max-rate oampdus | min-rate seconds
| mode {active | passive} | timeout seconds]
You can configure these optional OAM parameters:
• (Optional) Enter max-rate oampdus to configure the
maximum number of OAM PDUs sent per second. The
range is from 1 to 10.
• (Optional) Enter min-rate seconds to configure the
minimum transmission rate in seconds when one OAM
PDU is sent per second. The range is from 1 to 10.
• (Optional) Enter mode active to set OAM client mode
to active.
• (Optional) Enter mode passive to set OAM client
mode to passive.
Note When Ethernet OAM mode is enabled on two
interfaces passing traffic, at least one must be in the
active mode.
• (Optional) Enter timeout seconds to set a time for
OAM client timeout. The range is from 2 to 30.
Step 5
end Return to privileged EXEC mode.
Step 6
show ethernet oam status [interface interface-id] Verify the configuration.
Step 7
copy running-config startup-config (Optional) Save your entries in the configuration file.
