Command
fwd <4-30>
cur
When configuring STP bridge parameters, the following formulas must be used:
2*(fwd-1) ≥ mxage
2*(hello+1) ≤ mxage

Spanning Tree port configuration

Command: /cfg/l2/stp <1-128>/port <port number>
[Spanning Tree Port 1 Menu]
By default for STP/PVST+, Spanning tree is turned Off for downlink ports (1-16), and turned On for cross-
connect ports (17), and uplink ports (19-25). By default for RSTP/MSTP, Spanning tree is turned On for all
downlink ports (1-16), cross-connect ports (17), and all uplink ports (19-25), with downlink ports
configured as Edge ports.
Spanning tree port parameters are used to modify STP operation on an individual port basis. STP port
parameters include:
Port priority
Port path cost
Description
Configures the bridge forward delay parameter. The forward delay parameter specifies
the amount of time that a bridge port has to wait before it changes from the listening state
to the learning state and from the learning state to the forwarding state. The range is 4 to
30 seconds, and the default is 15 seconds.
This command does not apply to MSTP. See the "Common Internal Spanning Tree
configuration" section for more information.
Displays the current bridge STP parameters.
prior - Set port Priority (0-255)
cost - Set port Path Cost (1-65535 (802.1d) /

link - Set port link type (auto, p2p, or shared; default: auto)
edge - Enables or disables this port as an edge port
fastfwd - Enable/disable Port Fast Forwarding mode
on - Turn port's Spanning Tree ON
off - Turn port's Spanning Tree OFF
