11.6.8 Loopback Procedures
A loopback request is initiated by a MEP to verify the connectivity to a specified target MEP or
MIP in the network.
NOTE: Only one Loopback session can be active at a time for the entire system.
11.6.8.1 Initiating a Loopback Request
1. On the Maintenance End Point Attributes screen (Figure 11-21 for 802.1ag or Figure 11-
22 for Y.1731), type L and press Enter.
• If a Loopback request was already initiated from the MEP, a Loopback Monitoring
screen (Figure 11-29 for unicast, Figure 11-30 for sweep, or Figure 11-31 for mul-
ticast) opens.
• Otherwise, the Loopback Request screen (Figure 11-32) opens.
2. To change the loopback mode, on the Loopback Request screen, type 1 and press Enter.
• For 802.1ag, select unicast regular or unicast sweep.
• For Y.1731, select unicast regular, unicast sweep, or multicast.
Sweep loopback allows you to initiate a procedure for which the size of a loopback
message is automatically incremented by 1 Byte within a preset limit.
