Configuring Lb On Meps; Configuring Lt On Meps - HP 5900 Series Configuration Manual

Configurations in aggregate interface view take effect on the aggregate interface and all its
•
member ports.
Configurations on a member port take effect only when the member port leaves the aggregation
•
group.
To configure CC on a MEP:
Step
1. Enter system view.
2. (Optional.) Set the CCM
interval field.
3. Enter Layer 2 Ethernet
interface view or Layer 2
aggregate interface view.
4. Enable CCM sending on a
MEP.

Configuring LB on MEPs

The LB function can verify the link state between the local MEP and the remote MEP or MIP.
To configure LB on a MEP:
Task
Enable LB.

Configuring LT on MEPs

LT can trace the path between source and target MEPs, and can locate link faults by automatically
sending LT messages. The two functions are implemented in the following way:
• Tracing path—The source MEP first sends LTM messages to the target MEP. Based on the LTR
messages in response to the LTM messages, the path between the two MEPs is identified.
LT messages automatic sending—If the source MEP fails to receive the CCM frames from the target
•
MEP within 3.5 times the transmission interval, the link between the two is considered faulty. LTM
frames (with the target MEP as the destination and the TTL field in the LTM frames set to the
maximum value 255) will be sent out. Based on the LTRs that the MIPs return, the fault source is
located.
To configure LT on MEPs:
