Release M.10.37 Enhancements
Configuring MSTP Port Connectivity Parameters
With release K.12.04, all ports are configured as auto-edge-ports by default, and the spanning tree
edge-port option has been removed. This section describes selected spanning-tree <port-list> com-
mand parameters for enhanced operation.
Basic port connectivity parameters affect spanning-tree links at the global level. Therefore, in most
cases, ProCurve recommends that you use the revised default settings for these parameters and apply
changes on a per-port basis only where a non-default setting is clearly indicated by the circumstances
of individual links (for example, see the root-guard option below).
To display the spanning-tree settings for each port, use the show spanning-tree config command.
Syntax: [no] spanning-tree < port-list > < auto-edge-port | admin-edge-port | mcheck | root-guard |
tcn-guard >
[auto-edge-port ]
Enables auto-edge-port operation for MSTP, and supports the automatic detection
of edge ports. (Default: Yes, enabled)
The port will look for BPDUs for 3 seconds; if there are none it begins forwarding
packets. If admin-edge-port is enabled for a port, the setting for auto-edge-port is
ignored whether set to yes or no. If admin-edge-port is disabled, and auto-edge-
port has not been disabled, then the auto-edge-port setting controls the behavior
of the port.
The no spanning-tree < port-list > auto-edge-port command disables auto-edge-port
operation on the specified ports.
[ admin-edge-port ]
Enables admin-edge-port for RSTP/MSTP. If a bridge or switch is detected on the
segment, the port automatically operates as non-edge, not enabled. (Default: No
- disabled)
If admin-edge-port is disabled on a port and auto-edge-port has not been disabled,
the auto-edge-port setting controls the behavior of the port.
The no spanning-tree < port-list > admin-edge-port command disables admin-edge-
port operation on the specified ports.
[mcheck ]
Forces a port to send RSTP/MSTP BPDUs for 3 seconds. This allows for another
switch connected to the port and running RSTP to establish its connection
quickly and for identifying switches running 802.1D STP. If the whole-switch
force-version parameter is set to stp-compatible, the switch ignores the mcheck
setting and sends 802.1D STP BPDUs out all ports.
