Configuring Stp On The Blackdiamond - Extreme Networks BlackDiamond 6800 User Manual

Switch 2 has no ports assigned to VLAN marketing. Therefore, if the trunk for VLAN
marketing on Switches 1 and 3 is blocked, the traffic for VLAN marketing will not be
able to traverse the switches.

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>
The ports assigned to a STPD cannot be members of a load-sharing group.
• Enable STP for one or more STP domains using the following command:
enable stpd [<stpd_name> | all]
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
