Chapter 13 Spanning Tree Protocol Table 45 Advanced Application > Spanning Tree Protocol > RSTP (continued) LABEL DESCRIPTION Path Cost 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 42 on page 113 for more information. 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. 13.5 Rapid Spanning Tree Protocol Status Click Advanced Application > Spanning Tree Protocol in the navigation panel to display the status screen as shown next. See Section 13.1 on page 112 for more information on RSTP. Note: This screen is only available after you activate RSTP on the Switch. Figure 91 Advanced Application > Spanning Tree Protocol > Status: RSTP The following table describes the labels in this screen. Table 46 Advanced Application > Spanning Tree Protocol > Status: RSTP LABEL DESCRIPTION Configuration Click Configuration to specify which STP mode you want to activate. Click RSTP to edit RSTP settings on the Switch. Bridge Root refers to the base of the spanning tree (the root bridge). Our Bridge is this switch. This Switch may also be the root bridge. Bridge ID This is the unique identifier for this bridge, consisting of bridge priority plus MAC address. This ID is the same for Root and Our Bridge if the Switch is the root switch. Hello Time (second) This is the time interval (in seconds) at which the root switch transmits a configuration message. The root bridge determines Hello Time, Max Age and Forwarding Delay. Max Age (second) This is the maximum time (in seconds) the Switch can wait without receiving a configuration message before attempting to reconfigure. GS1920 Series User's Guide 118

Path Cost
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

Bridge
Root
refers to the base of the spanning tree (the root bridge).
Our Bridge
is this switch.
This Switch may also be the root bridge.
Bridge ID
This is the unique identifier for this bridge, consisting of bridge priority plus MAC address.
This ID is the same for

Hello Time
(second)
This is the time interval (in seconds) at which the root switch transmits a configuration
message. The root bridge determines Hello Time, Max Age and Forwarding Delay.
Max Age (second)
This is the maximum time (in seconds) the Switch can wait without receiving a
configuration message before attempting to reconfigure.
