Spanning-Tree Operation
802.1D Spanning-Tree Protocol (STP)
To Enable or Disable Fast Mode for a Switch Port: You can use either
the CLI or the menu interface to toggle between STP Fast mode and STP
Normal mode. (To use the menu interface, see
“Menu: Configuring 802.1D
STP” on page 6-21.)
Syntax: spanning-tree < port-list > mode <fast | norm>
For example, to configure Fast mode for ports C1-C3 and C5:
HPswitch(config)# spanning-tree c1-c3,c5 mode fast
Fast-Uplink Spanning Tree Protocol (STP)
Fast-Uplink STP is an option added to the switch’s 802.1D STP to improve the
recovery (convergence) time in wiring closet switches with redundant
uplinks. Specifically, a switch having redundant links toward the root device
can decrease the convergence time (or failover) to a new uplink (STP root)
port to as little as ten seconds. To realize this performance, the switch must be:
Used as a wiring closet switch (also termed an edge switch or a leaf
switch).
Configured for fast-uplink STP mode on two or more ports intended for
redundancy in the direction of the root switch, so that at any time only
one of the redundant ports is expected to be in the forwarding state.
Note Fast-Uplink STP operates only with 802.1D STP and is not available with the
Rapid STP (802.1w) feature (
6-9).
