Remote loopback
An OAM entity can put its remote entity into loopback mode using a loopback control OAMPDU. This
helps you ensure quality of links during installation or when troubleshooting. In loopback mode, each
frame received is transmitted back on that same port except for OAMPDUs and pause frames. The
periodic exchange of OAMPDUs must continue while in the loopback state to maintain the OAM
session. The loopback command is acknowledged by responding with an information OAMPDU with the
loopback state indicated in the state field.
NOTE
Brocade recommends to ensure that any higher layer protocol running over the local and remote
loopback ports does not block the interfaces in the VLAN on which loopback traffic testing is being
performed.
NOTE
Ethernet loopback and EFM-OAM remote loopback cannot be configured on the same interface.
NOTE
If EEE is enabled globally, port ceases to be in the remote loopback mode.
EFM-OAM error disable recovery
The error disable recovery feature enables the device to recover the EFM-OAM interface from the error-
disabled state caused by reception of a critical event from the remote device. Enter the
errdisable
recovery cause loam-critical-event
command to enable automatic recovery of ports from error-
disabled state.
The ports will recover automatically from the error-disabled state upon the expiry of the error disable
recovery timeout value.
Configuring EFM-OAM
The EFM-OAM configuration includes the following procedural steps to enable EFM-OAM on an
interface or multiple interfaces for advanced monitoring and maintenance of Ethernet network.
1. Enter the
configure terminal
command to enter global configuration mode.
device# configure terminal
2. Enter the
link-oam
command to enable the EFM-OAM protocol and enter EFM-OAM protocol
configuration mode.
device(config)# link-oam
device(config-link-oam)#
3. Enter the
timeout
command to configure the time in seconds for which the local Data Terminal
Equipment (DTE) waits to receive OAM Protocol Data Units (OAM-PDUs) from the remote entity.
device(config-link-oam)# timeout 5
4. Enter the
pdu-rate
command to configure the number of PDUs to be transmitted per second by the
DTE.
device(config-link-oam)# pdu-rate 2
5. Enter the
ethernet
command to enable EFM-OAM on an interface.
EFM-OAM can be enabled on more than one interface. You can also specify a range of interfaces to
enable EFM-OAM on multiple interfaces.
