Configuring the Limited Security Mode
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 58 to
configure the port with Limited security.
2. Type T to select Set Threshold.
