11.6.6.1 Initiating a Linktrace Request
You can initiate a link trace and monitor the results on a separate screen.
NOTE:
Only one Linktrace session can be active at a time for the entire system.
1. On the Maintenance End Point Attributes screen (Figure 11-22 for 802.1ag or Figure 11-22 for
Y.1731), type T and press Enter. If a linktrace request was already initiated from this MEP, the
Linktrace Monitoring screen (Figure 11-27) opens. Otherwise, the Linktrace Request screen
(Figure 11-26) opens.
2. To enter an address for the linktrace request, type 1 and press Enter. Select MAC address or
MEP ID and press Enter. You are prompted to type the address or ID. Type a MAC address or
MEP ID and press Enter.
3. To set the FDB only flag, type 2 and press Enter. If the FDB only flag is set to yes, the linktrace
response is sent to the originator only if the egress port for the destination MAC address is known
by the forwarding database and not through other methods. Select Yes or No and press Enter.
4. To set the Initial TTL (time to live) value for the LTM, type 3 and press Enter. The TTL value
indicates the number of nodes (SOAM-enabled L2 forwarding devices) the LTM will cross before it
is dropped. The default value is 64. If the LTM TTL is 0 or 1, the LTM is not forwarded to the next
node, and if 0, no LTR is generated.
5. Type a value between 2 and 255 and press Enter. The Linktrace Monitoring screen (Figure 11-26)
opens.
6. Press Esc to return to the Maintenance End Point Attributes screen.
7. To send the linktrace request, type S and press Enter.
