Cisco Catalyst 250 Series User Manual

If the stack master fails before the port-bounce completes, a port-bounce is initiated after stack master
change-over based on the original command (which is subsequently removed).
If the stack master fails before sending a CoA-ACK message, the new stack master treats the re-sent command
as a new command.
Stacking Guidelines for CoA-Request Disable-Port
Because the disable-port command is targeted at a session, not a port, if the session is not found, the command
cannot be executed.
When the Auth Manager command handler on the stack master receives a valid disable-port command, it
verifies this information before returning a CoA-ACK message:
•
the need for a port-disable
•
the port-id (found in the local session context)
The switch attempts to disable the port.
If the port-disable operation is successful, the signal that triggered the port-disable is removed from the standby
stack master.
If the stack master fails before the port-disable operation completes, the port is disabled after stack master
change-over based on the original command (which is subsequently removed).
If the stack master fails before sending a CoA-ACK message, the new stack master treats the re-sent command
as a new command.
Default RADIUS Configuration
RADIUS and AAA are disabled by default.
To prevent a lapse in security, you cannot configure RADIUS through a network management application.
When enabled, RADIUS can authenticate users accessing the switch through the CLI.
RADIUS Server Host
Switch-to-RADIUS-server communication involves several components:
•
Hostname or IP address
•
Authentication destination port
•
Accounting destination port
•
Key string
•
Timeout period
•
Retransmission value
You identify RADIUS security servers by their hostname or IP address, hostname and specific UDP port
numbers, or their IP address and specific UDP port numbers. The combination of the IP address and the UDP
port number creates a unique identifier, allowing different ports to be individually defined as RADIUS hosts
