11.6.7 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.
11.6.7.1 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 within a preset limit.
Once you select a loopback mode, the screen will change to display only the parameters
applicable to that mode. Number of packets, transmission rate, and Data TLV attributes
do not apply to sweep and multicast modes.
