AAA Monitor

AAA servers are monitored using the authentication probe mechanism. AAA servers are considered Up if the
authentication-probe receives a valid response. AAA servers are considered Down when the max-retries
count specified in the configuration of the AAA server has been reached. SRP initiates a switchover when
none of the configured AAA servers responds to an authentication probe. AAA probing is only performed on
the active chassis.
Important
If the newly active chassis fails to monitor the configured AAA servers, it remains as the active chassis until
one of the following occurs:
For release 20.0 and higher, ICSR will verify session manager connectivity on both chassis prior to allowing
a manual switchover. If one or more of the session managers in the active chassis is not connected on the
standby chassis, the switchover will not be initiated. An error message will appear on the screen noting
the number of session managers that are mismatched. The force keyword can be used to initiate the
switchover despite the mismatch(es). The output of the show checkpoint statistics verbose command
will not indicate "Ready" for a session manager instance ("smgr inst") in the "peer conn" column for any
instance that is not connected to the peer chassis.
A switchover event caused by an AAA monitoring failure is non-revertible.
Description
Displays statistics of an external audit.
Displays the history of calls lost during switchover.
Displays check pointing statistics on session redundancy data (session
managers, current call recovery records, etc.).
Displays Service Redundancy Protocol information (context, chassis
state, peer, connection state, etc.).
Displays SRP monitor information.
Displays SRP statistics (hello messages sent, configuration validation,
resource messages, switchovers, etc.).
