Verifying The Connectivity Of A Pw - Huawei Quidway S9300 Configuration Manual

5 PWE3 Configuration

5.10.1 Verifying the Connectivity of a PW

Context
To verify the connectivity of a PW, first configure basic PWE3 functions through the PW
template, and then run the following commands on U-PEs.
Procedure
Step 1 Run:
system-view
The system view of the U-PE is displayed.
Step 2 Run:
pw-template pw-template-name
The PW template view is displayed.
Step 3 Run:
control-word
The CW function is enabled.
Step 4 Run:
vccv cc { alert | cw }
The detection for PW connectivity is enabled.
Step 5 Run:
ping vc pw-type pw-id [ -c echo-number | -m time-value | -s data-bytes | -t timeout-
value | -v ]
The connectivity of a PW is detected in CW mode.
Step 6 Or run:
ping vc pw-type pw-id [ -c echo-number | -m time-value | -s data-bytes | -t timeout-
value | -v ]
The connectivity of a PW is detected in MPLS router alert mode.
----End
Example
To verify the connectivity of a PW in CW mode, you need to run the vccv cc cw cv lsp-ping
command on PW templates of the two U-PEs at both ends of the PW. Similarly, to verify the
connectivity of a PW in MPLS router alert mode, you need to run the vccv cc alert cv lsp-
ping command on PW templates on both ends of the PW.
At present, VCCV ping does not support the following:
l
l
5-34
*
cv lsp-ping
*
control-word [ remote peer-pw-id ]
*
label-alert [ remote remote-ip-address ]
The S-PEs do not support the commands. (The commands are supported only by U-PEs.)
Multiple users cannot run the commands simultaneously. That is, the devices on the two
ends cannot ping a VC at the same time. On a U-PE or an S-PE, if the PW serving as S-PE
is performing VCCV ping, the PW serving as U-PE will be unable to perform VCCV ping.
