seconds

•

seconds — Time in seconds. (Range: 4–30)

The default forwarding-time for IEEE Spanning-tree Protocol (STP) is 15 

seconds.

Global Configuration mode.

When configuring the Forward-Time the following relationship should be 

satisfied:

2*(Forward-Time - 1) >= Max-Age.

The following example configures spanning-tree bridge forward time to 25 

seconds.

console(config)#spanning-tree forward-time 25

The spanning-tree guard command selects whether loop guard or root guard 

is enabled on an interface. If neither is enabled, the port operates in 

accordance with the multiple spanning tree protocol. Use the “no” form of 

this command to disable loop guard or root guard on the interface.

spanning-tree guard {root | loop | none}

• root — Enables root guard.
•

loop — Enables loop guard

•

none — Disables root and loop guard.
