state. The forwarddelay value is in whole seconds within a range of 4 to 30, with the value being
greater than or equal to ((Bridge Max Age / 2) + 1).
Default 15
Format config spanningtree bridge forwarddelay <4-30>
config spanningtree bridge hellotime
Use this command to configure the Hello Time parameter to a new value. Hellotime determines how
often a hello message is broadcast; it cannot be longer than MaxAge but should be longer than
forwarddelay. The hellotime value is in whole seconds within a range of 1 to 10 with the value being
less than or equal to ((Bridge Max Age / 2) - 1).
Default 2
Format config spanningtree bridge hellotime <1-10>
config spanningtree bridge maxage
Use this command to configure the Bridge Max Age parameter to a new value. This is the value that
all bridges use for maxage when this bridge is acting as the root: A BPDU will be discarded when its
age exceeds maxage. The maxage value is in whole seconds within a range of 6 to 40, with the value
being less than or equal to (2 times (Bridge Forward Delay - 1)).
Default 6
Format config spanningtree bridge maxage <6-40>
config spanningtree bridge priority
Use this command to configure the Bridge Priority parameter to a new value. The bridge priority
value is the first two octets of the eight octet Bridge ID. This value is a number between 0 and
61440. The lower the number the higher the priority. The twelve least significant bits will be masked
according to the IEEE 802.1s specification. This will cause the priority to be rounded down to the
next lower valid priority.
Default 32768
Format config spanningtree bridge priority <0-61440>
show spanningtree bridge
Use this command to display the STP settings for the bridge.
Format show spanningtree bridge
Bridge Priority
The priority component of the bridge identifier. Valid values range from 0-61440, in
increments of 4096. The lower the number the higher the priority. The factory
default is 32768.
Bridge Identifier
The unique identifier associated with this bridge instance. It consists of the bridge
priority and the bridge’s base MAC address.
Bridge Max Age
The value that all bridges use for Max Age when this bridge is acting as the root: a
BPDU will be discarded when its age exceeds maxage.
Bridge Hello Time
The value that all bridges use for HelloTime when this bridge is acting as the root.
Hellotime determines how often a hello message is broadcast; it cannot be longer
than maxage but should be longer than forwarddelay.
