TL-SG2424P(config-if)# spanning-tree spanning-tree common-config Description The spanning-tree common-config command is used to configure the parameters of the ports for comparison in the CIST and the common parameters of all instances. To return to the default configuration, please use no spanning-tree common-config command. CIST (Common and Internal Spanning Tree) is the spanning tree in a switched network, connecting all devices in the network. Syntax spanning-tree common-config [ port-priority pri ] [ ext-cost ext-cost ] [ int-cost int-cost ] [ portfast { enable | disable }] [ point-to-point { auto | open | close }] no spanning-tree common-config Parameter pri ii Port Priority, which must be multiple of 16 ranging from 0 to 240. By default, the port priority is 128. Port Priority is an important criterion on determining if the port connected to this port will be chosen as the root port. In the same condition, the port with the highest priority will be chosen as the root port. The lower value has the higher priority. ext-cost ii External Path Cost, which is used to choose the path and calculate the path costs of ports in different MST regions. It is an important criterion on determining the root port. The lower value has the higher priority. It ranges from o to 2000000. By default, it is 0 which is mean auto. int-cost ii Internal Path Cost, which is used to choose the path and calculate the path costs of ports in an MST region. It is an important criterion on determining the root port. The lower value has the higher priority. By default, it is automatic. It ranges from o to 2000000. By default, it is 0 which is mean auto. portfast ii Enable/ Disable Edge Port. By default, it is disabled. The edge port can transit its state from blocking to forwarding rapidly without waiting for forward delay. point-to-point ii The P2P link status, with auto, open and close options. By default, the option is auto. If the two ports in the P2P link are root port or designated port, they can transit their states to forwarding rapidly to reduce the unnecessary forward delay. 108

Parameter
pri
——
Port Priority, which must be multiple of 16 ranging from 0 to 240. By
default, the port priority is 128. Port Priority is an important criterion on
determining if the port connected to this port will be chosen as the root port. In
the same condition, the port with the highest priority will be chosen as the root
port. The lower value has the higher priority.
ext-cost
——
External Path Cost, which is used to choose the path and
calculate the path costs of ports in different MST regions. It is an important
criterion on determining the root port. The lower value has the higher priority. It
ranges from o to 2000000. By default, it is 0 which is mean auto.
int-cost
——
Internal Path Cost, which is used to choose the path and calculate
the path costs of ports in an MST region. It is an important criterion on
determining the root port. The lower value has the higher priority. By default, it is
automatic. It ranges from o to 2000000. By default, it is 0 which is mean auto.
portfast
——
Enable/ Disable Edge Port. By default, it is disabled. The edge
port can transit its state from blocking to forwarding rapidly without waiting for
forward delay.
point-to-point
——
The P2P link status, with auto, open and close options. By
default, the option is auto. If the two ports in the P2P link are root port or
designated port, they can transit their states to forwarding rapidly to reduce the
unnecessary forward delay.
