Ethernet Loopback (ETH-LB)
Ethernet Loopback function supports fault verification through Loopback Messages (LBM)
and Loopback Reply (LBR). These messages are used during initial set-up or after a fault
has been detected to verify that the fault has occurred between two end points. Y.1731 al-
lows both unicast and multicast loopback.
To configure unicast or multicast ETH-LB function, use the following command.
Command
Mode
Description
ethernet oam ping meg NAME

<1-8191>
multicast
[
timeout
<1-1000>
priority
<0-7>]
Global
Sends LBM frames with multicast ETH-LB information.
1-8191: source MEP ID for LBMs to send
1-1000: the waiting time for expected reception of
LBRs (default: 5 seconds)
0-7: the priority of CCM or LTM messages (default:7)

}
[<1-

Sends LBM frames with uniicast ETH-LB information to
the configured remote MEP.
1-8191: source/destination MEP ID for LBMs to send
MACADDR: MAC address of a remote MEG
1-6000: the number of LBMs to be transmitted (de-
fault:1)
100-60000: interval for sending OAM PDUs (default:
1000ms)
1-1000: the waiting time for receiving the expected
response OAM PDUs (default: 5 seconds)
0-7: the priority of CCM or LTM messages (default:7)
5-1480: the length of data TLV (default:5)

Ethernet Link Trace (ETH-LT)
ETH-LT function is used to retrieve adjacency relationship between a MEP and a remote
MEP or MIP. And it is also used for fault localization. The V8102 sends LinkTrace Mes-
sage (LTM) frames to discover a path for a link trace.
To generate LTM frames, use the following command.
Command
Mode
Description
ethernet oam traceroute
meg NAME mepid
<1-
8191> {
rmepid
<1-8191> |
rmac MACADDR
} [

priority

]
Global
Sends LTM frames for a linktrace route.
1-8191: source/destination MEP ID to
send LTMs
MACADDR: destination MAC address to
send LTMs
1-64: LTM
’s TTL (default: 64)
