enable stp port
Syntax ENAble STP[={stp-name|ALL}] POrt={port-list|ALL}
where:
■ stp-name is a character string 1 to 15 characters long. Valid characters are
uppercase and lowercase letters, digits, the underscore, and the hyphen.
■ port-list is a port number, range (specified as n-m), or comma-separated list
of numbers and/or ranges. Port numbers start at 1 and end at m, where m
is the highest numbered switch Ethernet port, including uplink ports.
Description This command enables operation of the Spanning Tree Algorithm on the
specified ports.
On the Rapier i Series switches only, the STP parameter specifies the STP that is
to have ports enabled. If no value is entered, the default is ALL.
If the port parameter specified is all, then all ports within the matching STP
instance are enabled. This command is effective when the Spanning Tree
Algorithm is enabled for the STP to which the port belongs.
Enabling an STP port may cause reconfiguration of the Spanning Tree to which
the port belongs because STP messages (BPDUs) are generated on the port.
Enabling STP operation on a port may affect the operation of GARP. Each
GARP application has a GIP component whose actions depend upon whether
the port is in the STP forwarding state.
The disable stp command overrides the results of the disable stp port and
enable stp port commands. Once a STP has been disabled by this command it
is not possible to enable or disable any port belonging to that STP. The STP
must be enabled first before any port belonging to that STP can be enabled or
disabled.
Examples To enable the Spanning Tree Algorithm to use port 4, use the command:
ena atp po=4
To enable STP on all ports, use the command:
ena stp po=all
On a Rapier i Series switches only, to enable STP on just the administration
network and only on port 4, use the command:
ena stp=admin po=4
