HP 5500 HI Series Configuration Manual page 49

An HWTACACS server can function as the primary authorization server of one scheme and as the
•
secondary authorization server of another scheme at the same time.
The IP addresses of the primary and secondary authorization servers cannot be the same.
•
Otherwise, the configuration fails.
You can remove an authorization server only when no active TCP connection for sending
•
authorization packets is using it.
To specify HWTACACS authorization servers for an HWTACACS scheme:
Step
1. Enter system view.
2. Enter HWTACACS
scheme view.
3. Specify HWTACACS
authorization servers.
Specifying the HWTACACS accounting servers and the relevant parameters
For versions earlier than Release 5206, you can specify one primary accounting server and one
secondary accounting server for an HWTACACS scheme. When the primary server is not available, the
secondary server is used.
For Release 5206 and later versions, you can specify one primary accounting server and up to 16
secondary accounting servers for an HWTACACS scheme. When the primary server is not available, the
device tries to communicate with the secondary servers in the order they are configured. Once a
secondary server in active state is found, the device immediately uses it for HWTACACS accounting.
If redundancy is not required, specify only the primary server
When the switch 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 switch 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 switch discards the packet.
Follow these guidelines when you specify HWTACACS accounting servers:
An HWTACACS server can function as the primary accounting server of one scheme and as the
•
secondary accounting server of another scheme at the same time.
The IP addresses of the primary and secondary accounting servers cannot be the same. Otherwise,
•
the configuration fails.
You can remove an accounting server only when no active TCP connection for sending accounting
•
packets is using it.
