You can also include one or more of the STP per-port parameters in this
command. See “Reconfiguring Per-Port STP Operation on the Switch” on page
9-104.
Syntax: spanning-tree
priority <0 - 65355>
maximum-age <6 - 40 seconds>
hello-time <1 - 10 seconds>
forward-delay <4 - 30 seconds>
Default: See table 9-10, above.
For example, to enable STP with a maximum-age of 30 seconds and a hello-
time of 3 seconds:
SMC TigerSwitch 10/100(config)# spanning tree maximum-age
30 hello-time 3
Reconfiguring Per-Port STP Operation on the Switch. This command
enables STP (if not already enabled) and configures the following per-port
parameters:
Table 9-11.Per-Port STP Parameters
You can also include STP general parameters in this command. See “Recon-
figuring General STP Operation on the Switch” on page 9-103.
Syntax: spanning-tree ethernet <port-list>
path-cost <1 - 65535>
priority <0 - 255>
mode <norm | fast>
Default: See table 9-11, above.
Name Default Range Function
path-cost Ethernet: 100
10/100Tx: 10
100 Fx:
10
Gigabit: 5
1 - 65535 Assigns an individual port cost that the switch uses
to determine which ports are the forwarding ports.
priority 128 0 - 255 Used by STP to determine the port(s) to use for
forwarding. The port with the lowest number has
the highest priority.
mode norm norm
- or -
fast Specifies whether a port progresses through the
listening, learning, and forwarding (or blocking)
states (“norm” mode) or transitions directly to the
forwarding state (“fast” mode).
(For information on when to use Fast mode, see
“STP Fast Mode” on page 9-106.)
