Figure 71 Advanced Application > Spanning Tree Protocol > Status: MRSTP
Priority 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 Path cost is the cost of transmitting a frame on to a LAN through that
port. It is recommended that you assign this value according to the
speed of the bridge. The slower the media, the higher the cost - see
Table 26 on page 150 for more information.
Tree Select which STP tree configuration this port should participate in.
Apply Click Apply to save your changes to the Switch’s run-time memory. The
Switch loses these changes 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.
Cancel Click Cancel to begin configuring this screen afresh.
