- “z” is the hour number in the day. Its value is 0~23.
30 spanning-tree command
This command is used to configure spanning tree protocol of the switch. Entering
“spanning-tree”, the sub-commands will be shown.
(config)# spanning-tree ?
compatible Compatible with old STP
forward-time Global STA forward time configuration. Range: <4-30
seconds>
hello-time Global STA hello time configuration. Range: <1-10
seconds>
max-age Global STA maximum age configuration. Range <6-40
seconds>
priority Specifies spanning tree priority
spanning-tree command is used to enable spanning tree protocol function. And no
spanning-tree command is used to disable it.
spanning-tree compatible command is used to change its operation to 802.1D STP
instead of 802.1w RSTP. And no spanning-tree complatible command is used to set it
back.
spanning-tree forward-time x command is used to set the forwarding delay of
spanning tree operation. It is the maximum waiting time before changing states. This
delay is required because every device must receive information about topology
changes before it starts to forward frames. “x” is the delay time, and its valid value is
4-30 in seconds
spanning-tree hello-time x command is used to set the period to send spanning tree
maintenance packet if the switch is the root of spanning tree. “x” is the period time,
and its valid value is 1-10 in seconds.
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.
31 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).
