|
host <IP/HOSTNAME> |
Sets the TACACS server‘s IP address or hostname |
secret [0 <SECRET>| 2 <SECRET>| <SECRET>] |

configured
- <1-2> – Specify
the TACACS server index from 1 - 2.
|
retry-timeout-factor <50-200> |
Configures timeout scaling between two consecutive TACACS authentication
retries
- <50-200> –
Specify the scaling factor from 50 - 200. The default is 100.
A value of 100 indicates the interval between consecutive retires
remains the same irrespective of the number of retries.
A value
lesser than 100 indicates the interval between consecutive retries
reduces with each successive retry.
A value greater than 100
indicates the interval between consecutive retries increases with each
successive retry.
