Cnfrrtparm - Cisco MGX 8850 Command Reference Manual

cnfrrtparm

cnfrrtparm
Configure Reroute Retry Parameters—configures the waiting time intervals for rerouting a failed SPVC.
The cnfrrtparm command allows you configure the time periods that the switch waits between each
reroute retry attempt.
When an SPVC fails, the system immediately attempts to reroute the connection. If the first reroute
attempt fails, the switch keeps trying to reroute the connection according to the slow retry interval
(-slowtmr) and the fast retry interval base(-fasttmrbase).
The fast retry interval base is an incremental value (in 100-millisecond units) that is incremented each
time the switch attempts to reroute the connection and fails. The switch then waits the incremented
amount of time before it attempts to reroute the connection again. The fast retry interval base continues
to increment after each reroute attempt until it is equal to the slow retry interval value or until the reroute
succeeds.
The slow retry interval is a fixed value (in seconds) that occurs between all subsequent reroute attempts.
After the fast retry interval base reaches the slow retry interval, the switch attempts to reroute the
connection at the rate of the slow retry interval. No limit exists for the number of reroute attempts once
the slow retry interval begins.
For example, if the fast retry interval base is 50 100-millisecond intervals (5 seconds) and the slow retry
interval is 300 seconds (5 minutes), the switch attempts to reroute the connection 5 seconds after the first
attempt, 10 seconds after the second attempt, 15 seconds after the third attempt, and so on until the fast
retry interval base equals 300 seconds (5 minutes). After that, the switch continues to attempt to reroute
the connection every 5 minutes or until the reroute is successful.

The range for slow retry interval is 1–300 seconds. The default is 60 seconds. The
slow retry interval must be greater than fast retry interval base.
The fast retry interval base is a multiplier of 100-millisecond units. The range is
1–3000. The default is 50 100-milliseconds units (5 seconds).
