Object
column
r/w
Integer32
The value of the write-able portion of the Bridge ID
(i.e., the first two octets of the (8 octet long) Bridge
ID). The other (last) 6 octets of the Bridge ID are
given by the value of ieee8021BridgeBaseBridgeAddress.
On Bridges supporting IEEE 802.1t or IEEE 802.1w,
permissible values are 0-61440, in steps of 4096.
The value of this object MUST be retained across
reinitializations of the management system.
