Alteon OS Application Guide

The following rules apply to TACACS+ command authorization and logging:

„Only commands from a Console, Telnet, or SSH connection are sent for authorization and logging. SNMP, BBI, or file-copy commands (for example, TFTP or sync) are not sent.

„Only leaf-level commands are sent for authorization and logging. For example, /cfg is not sent, but /cfg/l3/tacacs/cauth is sent.

„The full path of each command is sent for authorization and logging. For example,

/cfg/sys/tacacs/cauth

„Command arguments are not sent for authorization. For /cauth ena, only /cauth is authorized. The command and its first argument are logged, if issued on the same line.

„Only executed commands are logged.

„Invalid commands are checked by Alteon OS, and are not sent for authorization or log- ging.

„Authorization is performed on each leaf-level command separately. If the user issues mul- tiple commands at once, each command is sent separately as a full path.

„Only the following global commands are sent for authorization and logging: apply

diff ping revert save telnet traceroute
