Purpose
Enter global configuration mode.
Configure the forward time of a VLAN. The forward delay is the
number of seconds an interface waits before changing from its
spanning-tree learning and listening states to the forwarding state.
For vlan-id, you can specify a single VLAN identified by
•
VLAN ID number, a range of VLANs separated by a hyphen,
or a series of VLANs separated by a comma. The range is
1 to 4094.
For seconds, the range is 4 to 30; the default is 15.
•
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
Purpose
