3.10 Port Security
Port Security allows you to restrict specific MAC addresses to reside in some port. For example,
a dummy hub is attached to some port for extension, and you just only allow 2 users to access
this port at the same time, you can use the port security window to set the parameters.
To restrict the number of MAC address to reside in a port, you must do the following :
Click the " Enable " checkbox for that port. IF the " Enable "checkbox is uncheck, there is no
MAC address count restriction for that port.
Type the number in the " Max Allowed MAC Address Count " edit for that port. The upper
bound of this number is the " Max Allowed MAC Address Count per port "
Press the " Press " button
The " Used Count " will tell you how many MAC address residing in the corresponding port now.
Note : A trunked port is not allowed to enable the port security option.
3.11 Port Priority-802.1p
There are two priority queues ( high and low ) on each port. Each port arbitrates between two
transmit queues ( high and low priority ).
The arbitration uses weighted round-robin between the high and low priority queues, and you
can adjust this weight.
