spanning-tree max-age x command is used to set the spanning tree aging time if no spanning tree maintenance
packet is received. “ x ” is the time, and its valid value is 6-40 in seconds.
spanning-tree priority x command is used to set the bridge priority of the switch. Bridge priority is for selecting the
root device, root port, and designated port. The device with the highest priority (lowest value) becomes the STA root
device. If all devices have the same priority, the device with the lowest MAC address will then become the root
device. “ x ” is the priority, and its valid value is 0-61440.
The settings of spanning tree on port are done in “interface” command. The settings here are for bridge only.
30 storm-control command
This command is used to set the storm control rate. The packet storms that could be controlled are broadcast,
multicast, and unicast flooding traffic. And the rate is counted with packet per second(pps), not bit per second(bps).
storm-control bc-rate x command is used to set rate limit for broadcast traffic. “ x ” is the limit rate number, and its
valid value is 0-7. (0:disable, 1:1Kpps, 2:2Kpps, 3:4Kpps, 4:8Kpps, 5:16Kpps, 6:32Kpps, 7:64Kpps)
storm-control mc-rate x command is used to set rate limit for multicast traffic. “ x ” is the limit rate number, and its
valid value is 0-7. (0:disable, 1:1Kpps, 2:2Kpps, 3:4Kpps, 4:8Kpps, 5:16Kpps, 6:32Kpps, 7:64Kpps)
storm-control fc-rate x command is used to set rate limit for unicast flooding traffic. “ x ” is the limit rate number,
and its valid value is 0-7. (0:disable, 1:1Kpps, 2:2Kpps, 3:4Kpps, 4:8Kpps, 5:16Kpps, 6:32Kpps, 7:64Kpps)
31 trunk command
This command is used to enable trunk function of the switch. And no trunk comand can be used to disable it.
The trunk function for the switch works with LACP protocol. The system priority of LACP is set by “lacp”
command. And the settings on ports is done in “interface” command.
