cnfrrtparm
Configure Reroute Retry Parameters—configures the waiting time intervals for rerouting a failed SPVC.
The cnfrrtparm command allows you configure the time periods t ha t t he s w it ch wa it s be tween each
reroute retry at t em pt.
When an SPVC fails, the system i m med i ate ly attempts to reroute the con ne cti on . I f t he first reroute
attempt fails, the switch keeps t ryin g to rer o ut e t he co nn ec ti on a c cording to the slow retry interva l
(-slowtmr) and the fast retry interval base(-fasttmrbase).
The fast retry interval base is an in cremental value (in 100-milliseco nd u n its) t ha t i s in cr em en ted ea ch
time the switch attempts to r er o ut e t he connection and fails. The s w itc h th en 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 atte mpt until it is equal to the slow retry in terval value or until the rerou te
succeeds.
The slow retry interval is a fixed value (in seconds) that occurs between all sub seque nt r erout e atte mpt s.
After the fast retry interval base reaches the slow retry interval, the switch a tte m p ts t o re ro u te th e
connection at the rate o f the slow retry interval. No li m it exists for the number of reroute attempts once
the slow retry interval begins.
For example, if the fast retry inter val base is 50 100-millisecond intervals (5 seconds) and the slow retry
interval is 300 seconds (5 minutes), the switch att empt s to rero ute th e con nectio n 5 sec onds af ter th e f irst
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.

-slowtmr The range for slow retry interval is 1–300 seconds. The default is 60 sec o nd s . T he
slow retry interval must be greater th an fast retry interval base.
-fasttmrbase The fast retry interval base is a multiplier of 100-millisecond units. The range is
