7705 SAR OS System Management Guide 25
When a user logs in to request access to the network using Telnet or SSH, or a user enters a
command for which accounting parameters are configured, or a system event occurs, such as
a reboot or a configuration file reload, the 7705 SAR checks the configuration to see if
TACACS+ accounting is required for the particular event.
If TACACS+ accounting is required, then, depending on the accounting record type
specified, the device sends a start packet to the TACACS+ accounting server that contains
information about the event.
The TACACS+ accounting server acknowledges the start packet and records information
about the event. When the event ends, the device sends a stop packet. The stop packet is
acknowledged by the TACACS+ accounting server.
