DES-3550 Fast Ethernet Layer 2 Switch
Switch will then go to the next technique listed in the server group for authentication, until the authentication has been
verified or denied, or the list is exhausted.
Please note that users granted access to the Switch will be granted normal user privileges on the Switch. To gain access to
administrator level privileges, the user must access the Enable Admin window and then enter a password, which was
previously configured by the administrator of the Switch.
NOTE: TACACS, XTACACS and TACACS+ are separate entities and are
not compatible. The Switch and the server must be configured exactly the
same, using the same protocol. (For example, if the Switch is set up for
TACACS authentication, so must be the host server.)

Parameters Description

the user. The user may set a time between 0 and 255 seconds. The default set-
ting is 30 seconds.
User Attempts (1-255)
This command will configure the maximum number of times the Switch will accept
authentication attempts. Users failing to be authenticated after the set amount of
attempts will be denied access to the Switch and will be locked out of further
authentication attempts. Command line interface users will have to wait 60
seconds before another authentication attempt. TELNET and web users will be
disconnected from the Switch. The user may set the number of attempts from 1 to
255. The default setting is 3.
