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 S3100
Ethernet switch regards another manufacturer's switch as in the same region; it records
the configuration digests carried in the BPDUs received from another manufacturer's
switch, and put them in the BPDUs to be sent to the another manufacturer's switch. In
this way, the S3100 Ethernet switch can communicate with another manufacturer’s
switches in the same MST region.
Caution:
The digest snooping function is not applicable to edge ports.
1.7.2 Configuring Digest Snooping
Configure the digest snooping feature on a switch to enable it to communicate with
other switches adopting proprietary protocols to calculate configuration digests in the
same MST region through MSTIs.
I. Configuration prerequisites
The switch to be configured is connected to another manufacturer's switch adopting a
proprietary spanning tree protocol. MSTP and the network operate normally.
