Symptom
We start with a config like this:
authentication periodic
authentication timer inactivity server dynamic
Then I tried to add the command "authentication timer reauthenticate server" using SNMP sets without success.
snmpset -v 2c -c community-string 10.20.2.251 1.3.6.1.4.1.9.9.656.1.2.1.1.7.10101 u 0
A value of zero indicates that the reauthentication interval is downloaded from AAA server
The command was not added by the SNMP set.
authentication periodic
authentication timer inactivity server dynamic
If we manually configure the command and then if we apply the SNMP set the "authentication timer reauthenticate server" command disappears.
authentication periodic
authentication timer reauthenticate server
authentication timer inactivity server dynamic
snmpset -v 2c -c community-string 10.20.2.251 1.3.6.1.4.1.9.9.656.1.2.1.1.7.10101 u 0
A value of zero indicates that the reauthentication interval is downloaded from AAA server
authentication periodic
authentication timer inactivity server dynamic
Conditions
