NOTE:
• An HWTACACS server can function as the primary authentication server of one scheme and as the
secondary authentication server of another scheme at the same time.
• The IP addresses of the primary and secondary authentication servers cannot be the same. Otherwise,
the configuration fails.
• You can remove an authentication server only when no active TCP connection for sendin
g
authentication
packets is using it.
Specifying the HWTACACS authorization servers
You can specify one primary authorization server and up to one secondary authorization server for an
HWTACACS scheme so that the NAS can find a server for user authorization when using the scheme.
When the primary server is not available, the secondary server is used, if any. In a scenario where
redundancy is not required, specify only the primary server.
Follow these steps to specify HWTACACS authorization servers for an HWTACACS scheme:

packets is using it.
Specifying the HWTACACS accounting servers and the relevant parameters
You can specify one primary accounting server and up to one secondary accounting server for an
HWTACACS scheme so that the NAS can find a server for user accounting when using the scheme.
When the primary server is not available, the secondary server is used, if any. In a scenario where
redundancy is not required, specify only the primary server.
When the device receives a connection teardown request from a host or a connection teardown
command from an administrator, it sends a stop-accounting request to the accounting server. You can
enable buffering of non-responded stop-accounting requests to allow the device to buffer and resend a
stop-accounting request until it receives a response or the number of stop-accounting attempts reaches
the configured limit. In the latter case, the device discards the packet.
Follow these steps to specify HWTACACS accounting servers and set relevant parameters for an
HWTACACS scheme:
