Enter the no ethernet oam interface configuration command to disable Ethernet OAM on the interface.

Enabling Ethernet OAM Remote Loopback

You must enable Ethernet OAM remote loopback on an interface for the local OAM client to initiate
OAM remote loopback operations. Changing this setting causes the local OAM client to exchange
configuration information with its remote peer. Remote loopback is disabled by default.
Remote loopback has these limitations:
•
•
•
Beginning in privileged EXEC mode, follow these steps to enable Ethernet OAM remote loopback on an
interface:
Command
Step 1 configure terminal
Step 2 interface interface-id
OL-9639-07
Internet Group Management Protocol (IGMP) packets are not looped back.
You cannot configure Ethernet OAM remote loopback on ISL ports or ports that belong to an
EtherChannel.
If dynamic ARP inspection is enabled, ARP or reverse ARP packets are not looped or dropped.
Purpose
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.
When Ethernet OAM mode is enabled on two
Note
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.
Return to privileged EXEC mode.
Verify the configuration.
(Optional) Save your entries in the configuration file.
Purpose
Enter global configuration mode.
Define an interface to configure as an OAM interface, and
enter interface configuration mode.
