SET SWITCH THRESHOLD
Syntax
set switch threshold=threshold port=port|all
Parameters
threshold Specifies the maximum number of dynamic MAC
addresses a port on the switch can learn. The range is
1 to 150 addresses. The default is 100.
port Specifies the port whose threshold you want to
change. You can specify more than one port at a time.
You can specify the ports individually (e.g., 2,3,5), as a
range (e.g., 7-9), or both (e.g., 2,5,7-9). To assign the
same threshold to all ports on the switch, use ALL.
Description
This command is used when the switch is operating in the Limited
security mode. The Limited security mode allows you to set a maximum
number of dynamic MAC addresses each port on a switch can learn.
Once a port has learned its maximum number of MAC addresses, it
discards frames with new source MAC addresses.
You can assign the same threshold limit to all ports or different limits to
different ports.
Example
The following command sets a threshold limit of 75 dynamic MAC
addresses on Ports 5 through 7:
set switch threshold=75 port=5-7
