Login These fields specify which database the Switch should use (first, second and third)
to authenticate administrator accounts (users for Switch management).
Configure the local user accounts in the Access Control > Logins screen. The
TACACS+ and RADIUS are external servers. Before you specify the priority, make
sure you have set up the corresponding database correctly first.
You can specify up to three methods for the Switch to authenticate administrator
accounts. The Switch checks the methods in the order you configure them (first
Method 1, then Method 2 and finally Method 3). You must configure the settings in
the Method 1 field. If you want the Switch to check other sources for administrator
accounts, specify them in Method 2 and Method 3 fields.
Select local to have the Switch check the administrator accounts configured in the
Access Control > Logins screen.
Select radius to have the Switch authenticate the administrator accounts through a
RADIUS server.
Select tacacs+ to have the Switch authenticate the administrator accounts through
a TACACS+ server.
Accounting Use this section to configure accounting settings on the Switch.
Update Period This is the amount of time in minutes before the Switch sends an update to the
accounting server. This is only valid if you select the start-stop option for the Exec
or Dot1x entries.
Type The Switch supports the following types of events to be sent to the accounting
server(s):
•
System - Configure the Switch to send information when the following system
events occur: system boots up, system shuts down, system accounting is
enabled, system accounting is disabled
• Exec - Configure the Switch to send information when an administrator logs in
and logs out via the console port, telnet or SSH.
• Dot1x - Configure the Switch to send information when an IEEE 802.1x client
begins a session (authenticates via the Switch), ends a session as well as
interim updates of a session.
• Commands - Configure the Switch to send information when commands of
specified privilege level and higher are executed on the Switch.
Active Select this to activate accounting for a specified event types.
Broadcast Select this to have the Switch send accounting information to all configured
accounting servers at the same time.
If you don’t select this and you have two accounting servers set up, then the Switch
sends information to the first accounting server and if it doesn’t get a response from
the accounting server then it tries the second accounting server.
Mode The Switch supports two modes of recording login events. Select:
•
start-stop - to have the Switch send information to the accounting server when
a user begins a session, during a user’s session (if it lasts past the Update
Period), and when a user ends a session.
• stop-only - to have the Switch send information to the accounting server only
when a user ends a session.
Method Select whether you want to use RADIUS or TACACS+ for accounting of specific
types of events.
TACACS+ is the only method for recording Commands type of event.
Privilege This field is only configurable for Commands type of event. Select the threshold
command privilege level for which the Switch should send accounting information.
The Switch will send accounting information when commands at the level you
specify and higher are executed on the Switch.
