between them. (A configuration ID contains information such as region ID and
configuration digest.)
As some partners' switches adopt proprietary spanning tree protocols, they cannot
interwork with other switches in an MST region even if they are configured with the
same MST region-related settings as other switches in the MST region.
This problem can be overcome by implementing the digest snooping feature. If a port
on a S5600 series switch is connected to a partner's switch that has the same MST
region-related configuration as its own but adopts a proprietary spanning tree protocol,
you can enable digest snooping on the port. Then the S5600 series switch regards the
partner's switch as in the same region; it records the configuration digests carried in the
BPDUs received from the partner's switch, and put them in the BPDUs to be send to the
partner's switch. In this way, the S5600 series switches can interwork with the partners'
switches in the same MST region.
1.6.2 Digest Snooping Configuration
Configure the digest snooping feature on a switch to enable it to interwork with other
switches that adopt proprietary protocols to calculate configuration digests in the same
MST region through MSTIs.
I. Prerequisites
The switch to be configured is connected to a partner's switch that adopts a proprietary
spanning tree protocol. The MSTP network operates normally.
