Parameter Description
State Synopsis: { Disabled, Enabled }
Default: Enabled
Enable STP/RSTP/MSTP for the bridge globally. Note that STP/RSTP/MSTP is enabled
on a port when it is enabled globally and along with enabling per port setting.
Version Support Synopsis: { STP, RSTP, MSTP }
Default: RSTP
Selects the version of Spanning Tree Protocol to support, either only STP or Rapid STP
or Multiple STP.
Bridge Priority Synopsis: { 0, 4096, 8192, 12288, 16384, 20480, 24576, 28672, 32768, 36864,
40960, 45056, 49152, 53248, 57344, 61440 }
Default: 32768
Bridge Priority provides a way to control the topology of the STP connected network.
The desired Root and Designated bridges can be configured for a particular topology.
The bridge with the lowest priority will become root. In the event of a failure of the root
bridge, the bridge with the next lowest priority will then become root. Designated bridges
that (for redundancy purposes) service a common LAN also use priority to determine
which bridge is active. In this way careful selection of Bridge Priorities can establish the
path of traffic flows in normal and abnormal conditions.
Hello Time Synopsis: 1 to 10 s
Default: 2 s
Time between configuration messages issued by the root bridge. Shorter hello times
result in faster detection of topology changes at the expense of moderate increases in
STP traffic.
Max Age Time Synopsis: 6 to 40 s
Default: 20 s
The time for which a configuration message remains valid after being issued by the root
bridge. Configure this parameter with care when many tiers of bridges exist, or slow
speed links (such as those used in WANs) are part of the network
Transmit Count Synopsis: 3 to 100 or { Unlimited }
Default: Unlimited
