operation mode of spanning tree. It could be MSTP, RSTP, or STP.
spanning-tree msti instance x vlan y
command is used to add a VLAN to a
MSTI. “
x
” is a number between 1~7 to indicate the MSTI. “
y”
is the VLAN ID
(1~4094) of the VLAN added to the MSTI. A VLAN can only be mapped
to one MSTI. An unused MSTI should just be left empty. (i.e. not having any
VLANs mapped to it.)
spanning-tree msti priority x y
command is used to set the bridge instance
priority. “
x
” is a number between 1~7 to indicate the MSTI. “
y
” is the bridge
instance priority between 0~61440 i
n steps of 4096. (For example, “
y
” could
be 0, 4096, 8192, 12288, ...) Lower numeric values have better priority. The
bridge priority plus the MSTI instance number, concatenated with the 6 -byte
MAC address of the switch forms a
Bridge Identifier .
spanning-tree priority x
command is used to specify spanning tree priority.
“
x
” is a value of spanning-tree priority between 0~61440 in steps of 4096.
(For example, “
x
” could be 0, 4096, 8192, 12288, ...) Lower numeric values
have better priority. For MSTP operation, this is the priority of the CIST.
Otherwise, this is the priority of the STP/RSTP bridge. The bridge priority
plus the MSTI instance number, concatenated with the 6 -byte MAC address of
the switch forms a Bridge Identifier.
spanning-tree recovery x
command is used to set edge port error recovery
timeout. It is the time to pass before a port in the error-disab led state can be
enabled. “
x
” is the timeout value. Valid values are between 30 and 86400
seconds (24 hours).
spanning-tree transmit-hop-count x
command is used to set the STP Bridge
Transmit Hold Count parameter. It is the number of BPDU's a bridge port
can send per second. When exceeded, transmission of the next BPDU will be
delayed. “
x
” is the Transmit Hold Count. Valid values are in the range 1 to
10 BPDU's per second.
The settings of spanning tree on port are done in “interface” command. The
settings here are for bridge only.

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).
These only affect flooded frames, i.e. frames with a (VLAN ID, DMAC) pair not
present on the MAC Address table.
storm-control broadcast x
command is used to set broadcast flooding traffic
suppression rate. “
x
” is the suppression rate in pps(packet per second),
and could be 1, 2, 4, 8, ..., 512, 1k, 2k, 4k, ..., 512k, 1024k, 2048k, ..., 32768k.
storm-control multicast x
command is used to set multicast flooding traffic
suppression rate. “
x
” is the suppression rate in pps(packet per second),
