166 Clearing Spanning Tree Protocol Statistics
Parameter Description
Priority Synopsis: { 0, 16, 32, 48, 64, 80, 96, 112, 128, 144, 160, 176, 192, 208, 224, 240 }
Default: 128
Selects the STP port priority. Ports of the same cost that attach to a common LAN will
select the port to be used based upon the port priority.
STP Cost Synopsis: 0 to 65535 or { Auto }
Default: Auto
Selects the cost to use in cost calculations, when the Cost Style parameter is set to STP
in the Bridge RSTP Parameters configuration. Setting the cost manually provides the
ability to preferentially select specific ports to carry traffic over others. Leave this field
set to "auto" to use the standard STP port costs as negotiated (4 for 1Gbps, 19 for 100
Mbps links and 100 for 10 Mbps links).
For MSTP, this parameter applies to both external and internal path cost.
RSTP Cost Synopsis: 0 to 2147483647 or { Auto }
Default: Auto
Selects the cost to use in cost calculations, when the Cost Style parameter is set to
RSTP in the Bridge RSTP Parameters configuration. Setting the cost manually provides
the ability to preferentially select specific ports to carry traffic over others. Leave this
field set to "auto" to use the standard RSTP port costs as negotiated (20,000 for 1Gbps,
200,000 for 100 Mbps links and 2,000,000 for 10 Mbps links).
For MSTP, this parameter applies to both external and internal path cost.
