Figure 7-4 STP ConfigThe following entries are displayed on this screen:‣ Global ConfigSTP:Version:Select Enable/Disable STP function globally on the switch.Select the desired STP version on the switch.• STP: Spanning Tree Protocol.• RSTP: Rapid Spanning Tree Protocol.• MSTP: Multiple Spanning Tree Protocol.‣ Parameters ConfigCIST Priority:Hello TimeMax Age:Forward Delay:TxHold Count:Max Hops:Enter a value from 0 to 61440 to specify the priority of the switchfor comparison in the CIST. CIST priority is an important criterionon determining the root bridge. In the same condition, the switchwith the highest priority will be chosen as the root bridge. Thelower value has the higher priority. The default value is 32768 andshould be exact divisor of 4096.Enter a value from 1 to 10 in seconds to specify the interval tosend BPDU packets. It is used to test the links. 2*(Hello Time + 1)≤ Max Age. The default value is 2 seconds.Enter a value from 6 to 40 in seconds to specify the maximumtime the switch can wait without receiving a BPDU beforeattempting to reconfigure. The default value is 20 seconds.Enter a value from 4 to 30 in seconds to specify the time for theport to transit its state after the network topology is changed.2*(Forward Delay-1) ≥ Max Age. The default value is 15 seconds.Enter a value from 1 to 20 to set the maximum number of BPDUpackets transmitted per Hello Time interval. The default value is5pps.Enter a value from 1 to 40 to set the maximum number of hops75
