(STP)
Configuring STP on
the Switch
STP configuration involves the following actions:
■
Create one or more STP domains using the following command:
create stpd <stpd_name>
STPD, VLAN, and QoS profile names must all be unique. For example, a
name used to identify a VLAN cannot be used when you create an STPD
or a QoS profile.
■
Add one or more VLANs to the STPD using the following command:
config stpd <stpd_name> add vlan <name>
■
Enable STP for one or more STP domains using the following
command:
enable stpd {<stpd_name>}
All VLANs belong to a STPD. If you do not want to run STP on a VLAN,
you must add the VLAN to a STPD that is disabled.
Once you have created the STPD, you can optionally configure STP
parameters for the STPD.
You should not configure any STP parameters unless you have
considerable knowledge and experience with STP. The default STP
parameters are adequate for most networks.
The following parameters can be configured on each STPD:
■
Hello time
■
Forward delay
■
Max age
■
Bridge priority
The following parameters can be configured on each port:
■
Path cost
■
Port priority
The device supports the RFC 1493 Bridge MIB. Parameters of only the
default STPD (named s0) STPD are accessible through this MIB.
