Spanning-Tree System Settings
Description- Configure STP system settings used by all STP Bridge instances in the switch.
Basic STP global setting commands:
spanning-tree mst
<instance=0>
priority
<prio>
spanning-tree mst hello-time
<hellotime>
spanning-tree mst forward-time
<fwdtime>
spanning-tree mst max-age
<maxage> [ forward-time <fwdtime> ]
spanning-tree mst max-hops
<maxhops>
spanning-tree transmit hold-coun
t <holdcount>
Advanced STP global setting commands:
spanning-tree edge bpdu-filter
spanning-tree edge bpdu-guard
spanning-tree recovery interval <interval>
Parameter
Description
Parameter
<instance>
STP bridge instance. Must be 0 (zero)
priority <prio>
Bridge Priority Supported values are 0-61440. Only values divisible by
4096 are allowed. For example, 4096, 8192, etc. Default value is 32768.
<hellotime>
Interval between sending STP BPDUs. Valid values are 1-10 seconds.
Default is 2 seconds.
<fwdtime>
Forward delay used by STP Bridges to transit Root and Designated Ports
to Forwarding. Valid values are 4-30 seconds. Default is 15..
<maxage>
Maximum age of the information transmitted by the Bridge when it is a
Root Bridge. Valid values are 6-40 seconds. Default is 20..
<maxhops>
Defines how many bridges a root bridge can distribute its
BPDU information. Valid values are 6-40 hops. Default is 20
<holdcount>
Number of BPDUs a bridge port can send per second. Valid range 1-10
BPDUs per second. Default is 6.
<interval>
Time to pass before a port in error-disabled state can be enabled. Values
are 30-86400 seconds (24 hours). Default is port error recovery
disabled.
