Inspecting Pws - HP 12500 Series Configuration Manual

If the AC interface is a Layer 2 interface, create a service instance on the interface, apply global
•
committed access rate (CAR) actions for the service instance, and then bind the service instance to
a VPLS instance.
This configuration task describes how to apply a CAR action for a service instance.
Configuration prerequisites
Use the qos car command in system view to configure a global CAR action. For more information about
CAR, see ACL and QoS Configuration Guide.
Configuration procedure
After you apply a global CAR action in service instance view, the device polices the inbound or
outbound traffic matching the service instance according to the applied global CAR action.
To apply a global CAR action for a service instance:
To do...
Enter system view
Enter the view of the Layer 2 Ethernet
interface connected to the CE
Enter service instance view
Apply a global CAR action to the
inbound or outbound traffic on the AC
NOTE:
To configure traffic policing for an AC, you must first configure this task before you bind the service
instance to the VPLS instance.

Inspecting PWs

On a VPLS network, you can use the MPLS LSP ping function to check PW connectivity and get necessary
information for troubleshooting PW failures.
On the local PE, the MPLS LSP ping function adds the label of the PW to be tested into MPLS Echo Request
messages so that the messages travel along the PW. The local PE determines whether the PW is valid and
reachable according to the replies received from the peer PE.
To check the connectivity of a PW:
To do...
Use MPLS LSP ping to check the
connectivity of a PW
Use the command...
system-view
interface interface-type
interface-number
service-instance instance-id
car { inbound | outbound } name
car-name
Use the command...
ping lsp [ -a source-ip | -c count |
-exp exp-value | -h ttl-value | -m
wait-time | -r reply-mode | -s
packet-size | -t time-out | -v ] * pw
ip-address pw-id pw-id
