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.
The stp-name cannot be all.
■ 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 STP debugging for the specified STP, or ports. Be aware
that enabling debug could flood the receiving Telnet session or asynchronous
port with raw data. If an stp is specified, except on the Rapier i Series switches,
the port parameter is invalid.
The stp parameter specifies the STP for which the debugging mode is enabled.
On the Rapier i Series switches only, if an STP is specified and ports are
specified with the port parameter, then debug is enabled on the specified port
on the specified STP. If an stp is not specified or all is specified with the stp
parameter, and ports are specified with the port parameter, then debug mode
for the listed ports is enabled on the STPs with the listed port as a member.
The debug parameter specifies the debugging modes that are to be enabled. If
all is specified, all debugging modes for the STP or ports are enabled. The other
modes can be enabled independently of each other. The debug parameter must
be specified before the port parameter. The debugging modes enabled by each
option are shown in Table 8-25 on page 8-128.
The output parameter set to console specifies that the debugging information
produced is sent to the console. The debugging data is by default sent to the
port on which it received the enable stp debug command. Use this option if
the enable stp debug command is used in a script, since a script is not received
on a port.
The port parameter specifies the ports where the debug mode is enabled, or all
ports on the switch. The debug parameter must be specified before the port

are displayed as well the current role of the port.
