stpGroupAddress
Sets the single address to which a bridge listens to receive Spanning Tree
Protocol (STP) information. Each STP bridge on the network sends STP
packets to the group address. Every STP bridge on the network receives
STP packets that were sent to the group address, regardless of which
bridge sent the packets. The current value is shown in the
stpGroupAddress field of the
bridge display
.
Valid Minimum Abbreviation
b sp stpg
Important Considerations
■
Because there is no industry standard for a group address, products
from different vendors may respond to different group addresses. If
STP does not seem to be working in a mixed-vendor environment,
other vendors’ products may use different group addresses as their
defaults. If that is true, set the STP group address to be the same
across all bridges in the network.
■
Before you can modify the STP group address, you must disable STP (if
it is not already disabled) on the bridge. (See “bridge spanningTree
stpState” earlier in this chapter.)
