Retransmit

Retransmit is the number of times, in the range 1 to 1000, a RADIUS request is retransmitted to a
server that is not responding. If the server has not responded after the last retransmit, it is
considered t o b e d ead.
Deadtime

Deadtime, which can be set to a number between 0 to 1440 minutes, is the period during which
the s witch w ill n ot s end n ew r equests t o a s erver t hat h as f ailed t o r espond t o a p revious r equest.
This will stop the switch from continually trying to contact a server that it has already determined
as dead. Setting the Deadtime to a value greater than 0 (zero) will enable this feature, but only if
more t han o ne s erver h as b een c onfigured.
