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.
Bridge Forward Delay
The value that all bridges use for Forward Delay when this bridge is acting as the
root. Forwarddelay is used by bridges to ensure that a new network topology has
stabilized before leaving the blocking state. Note that IEEE 802.1D specifies that
the range for this parameter is related to the value of STP Bridge Maximum Age.
Bridge Hold Time
Minimum time between transmission of Configuration Bridge Protocol Data Units
(BPDUs).
