Setting a Threshold
The Limited security mode lets you set a maximum number of dynamic
MAC addresses a port on a switch can learn. Once the maximum number
of MAC addresses have been learned by a port, frames with new source
MAC addresses are discarded and are not forwarded by the port.
Static MAC addresses are not included in the count of the maximum
MAC addresses a port can learn. You can continue to add static MAC
addresses even after a port has learned its maximum number of dynamic
MAC addresses.
To configure Limited security mode for a port, perform the following
procedure:
1. Perform the procedure
Configuring Port Security
on page 61 to
configure the port with Limited security.
2. Type
T
to select Set Threshold.
The following prompt is displayed:
Set threshold->Enter port number >
Port number is in range of 1 to 26
3. Enter the number of the port you want to configure. Press Return.
The following prompt is displayed:
Set threshold->Enter port number >
Threshold is in range of 1 to 170
4. Enter the number of dynamic MAC addresses you want the port to be
able to learn. This will be the new threshold for the port and will be
displayed immediately in the Port Security Configuration Menu.
Note
Threshold is not supported in Normal and Secure modes.
