DESCRIPTION
This field displays the port number. In stacking mode, the first number represents the slot ID and
the second is the port number. Please note that the default stacking ports (the last four ports
of your Switch) cannot be configured. They are reserved for stacking only.
Settings in this row apply to all ports.
Use this row only if you want to make some settings the same for all ports. Use this row first to set
the common settings and then make adjustments on a port-by-port basis.
Note: Changes in this row are copied to all the ports as soon as you make them.
Select this check box to add this port to the MST instance.
Configure the priority for each port here.
Priority decides which port should be disabled when more than one port forms a loop in the
Switch. Ports with a higher priority numeric value are disabled first. The allowed range is
between 0 and 255 and the default value is 128.
Path cost is the cost of transmitting a frame on to a LAN through that port. It is recommended
to assign this value according to the speed of the bridge. The slower the media, the higher the
cost - see Table 55 on page 153
Click this to create a new entry or to update an existing one.
This saves your changes to the Switch's run-time memory. The Switch loses this change if it is
turned off or loses power, so use the Save link on the top navigation panel to save your
changes to the non-volatile memory when you are done configuring.
Click Cancel to begin configuring this screen afresh.
This field displays the ID of an MST instance.
