Chapter 14 Value-Added Services (VAS) Traffic Forwarding
Configuring VAS Traffic Forwarding
From the SCE(config if)# prompt, type:
Disabling VAS Traffic Forwarding
Disabling the VAS Traffic Forwarding feature in runtime must be done with special care. There are two
points to consider:
•
You cannot disable VAS mode in the Cisco SCE platform while the applied SCA BB policy instructs
the Cisco SCE platform to forward traffic to the VAS servers.
Therefore, you must dismiss all VAS Traffic forwarding rules in the applied SCA BB policy before
disabling the VAS traffic forwarding in the Cisco SCE platform.
•
After the SCA BB has been reconfigured, there may still be some open flows that have already been
forwarded to the VAS servers. If the VAS feature is stopped while there are still such flows open,
their packets coming back from the VAS servers may be routed to their original destination with the
VLAN tag of the VAS server on it.
Therefore, it is also highly recommended to shutdown the line card before you disable the VAS
traffic forwarding in the Cisco SCE platform to avoid inconsistency with flows that were already
forwarded to the VAS servers.
Step 1
From the SCA BB console, remove all the VAS table associations to packages and apply the changed
policy.
Step 2
From the SCE(config if)# prompt, type
shutdown
and press
Enter
.
Shuts down the line card.
Step 3
From the SCE(config if)# prompt, type
no VAS-traffic-forwarding
and press
Enter
.
Disables VAS traffic forwarding.
Step 4
From the SCE(config if)# prompt, type
no shutdown
and press
Enter
.
Re-enables the line card.
Configuring the VAS Traffic Link
By default, the VAS traffic is transmitted on Link 1. If the VAS servers are connected on Link 0, you
must configure the VAS traffic link to Link 0.
Note
The VAS traffic link should be in Forwarding mode.
