Enter the age time (10 to 1million seconds) for the associated VLAN.
This is the amount of time that the entry remains in the bridge
forwarding table. The default is 300.
Select the current STP mode using the SPACE bar. You can select one
of the following: IEEE, PVSTP, NONE, and DEC. The default setting
is IEEE.
It is recommended that all switches in the network be configured for
the same STP mode setting.
IEEE = 802.1w Spanning Tree Protocol – A single spanning tree for
the entire network. Redundant links are placed in standby mode. States
are predetermined to ensure an accelerated failover.
PVSTP = Per VLAN Spanning Tree Protocol – PVSTP is also known
as the Spanning Forest. PVSTP allows each VLAN to have its own
spanning tree, which allows multiple links to be active, each assigned
to a different VLAN.
NONE = Spanning tree is not enabled.
DEC = DEC spanning tree protocol.
Enter the number of the VLAN to be added or deleted from the VLAN
list.
The default value is 2.
Add or Delete the VLAN entered in the VLAN field. This field is
toggled using the SPACE bar.
The default value is Add.
Implement the new configuration to all static VLANs and update the
VLAN list to include those new static VLANs.
