Enabling And Disabling The Soft Reroute Ie - Cisco MGX 8850 (PXM1E/PXM45) Configuration Manual

Managing Connection Grooming
When configuring the AIS delay, consider the following guidelines:
•
•
•
•
The AIS delay feature is disabled by default. To change the AIS delay period, enter the cnfaisdelaytimer
command as follows:
PXM1E_SJ.7.PXM.a > cnfaisdelaytimer <timer_value>
Replace the timer_value variable with a number in the range of 0 to 60. If you enter 0, the AIS delay is
disabled. To enable the AIS delay and select a delay time, enter a number in the range of 1 to 60 seconds.
The following example enables the AIS delay timer, sets the delay to 15 seconds, and uses the
dspaisdelaytimer command to display the configuration change.
PXM1E_SJ.7.PXM.a > cnfaisdelaytimer 15
PXM1E_SJ.7.PXM.a > dspaisdelaytimer
AIS Delay Timer:15 seconds

Enabling and Disabling the Soft Reroute IE

When soft rerouting is enabled and the grooming operation sets up a new connection, the soft reroute
information element (IE) is forwarded along the new route as part of the soft reroute capability
negotiation. If any switch along the call route cannot accept the soft reroute IE, you can block forwarding
of the IE on the appropriate interface.
Use the following procedure to manage the forwarding of the soft reroute IE.
Establish a configuration session using a user name with GROUP1 privileges or higher.
Step 1
Step 2 Enter the dsppnportie <portid> command as follows to display the current configuration for the soft
reroute IE feature. Replace <portid
slot:bay.line:ifnum.(You can use the dsppnports command to display port numbers in use.)
PXM1E_SJ.7.PXM.a > dsppnportie 7:2.11:11
IE Options for port : 7:2.11:11
PS IE Option
CUG IE Option
Soft Reroute IE Option
Step 3 Enter the cnfpnportie command as follows to change the soft rereoute IE configuration.
M8850_LA.7.PXM.a > cnfpnportie <portid> [-srie auto|allowed|disallowed]
Replace <portid> with the port identifier in the format slot:bay.port:interface. You can view the
configured port numbers by entering the dsppnports command.

The AIS delay timer applies only to persistent (double-ended) P2P connections.
The AIS delay timer only applies during connection grooming. If an AIS is generated for another
reason, such as a failed link, the AIS is sent immediately.
We recommend that the AIS delay feature remain disabled until all network nodes have been
upgraded to Cisco MGX software Release 4 or later.
During switchover, the configured AIS delay may be doubled as it is applied to one PXM and then
the other.
