Protocols And Standards; Cfd Configuration Task List - HP A5830 series Configuration Manual

Loopback
Similar to ping at the IP layer, loopback verifies the connectivity between a local device and a remote
device. To implement this function, the local MEP sends LBMs to the remote MEP. Depending on whether
the local MEP can receive a LBR from the remote MEP, the link state between the two can be verified.
LBM frames and LBR frames are unicast frames.
Linktrace
Linktrace identifies the path between the source MEP and the target MEP. This function is implemented in
the following way:
Source MEP sends the LTMs to the target MEP.
•
After receiving the messages, the target MEP and the MIPs that the LTM frames pass send back LTRs
•
to the source MEP.
Based on the reply messages, the source MEP can identify the path to the target MEP.
•
LTM frames are multicast frames and LTRs are unicast frames.

CFD configuration task list

For CFD to work properly, design the network by performing the following tasks:
Grade the MDs in the entire network, and define the boundary of each MD.
•
Assign a name for each MD. Make sure that the same MD has the same name on different devices.
•
Define the MA in each MD according to the VLAN you want to monitor.
•
Assign a name for each MA. Make sure that the same MA in the same MD has the same name on
•
different devices.
Determine the MEP list of each MA in each MD. Make sure that devices in the same MA maintain
•
the same MEP list.
At the edges of MD and MA, MEPs should be designed at the device port. MIPs can be designed
•
on devices or ports that are not at the edges.
Complete the following tasks to configure CFD:
