You must enable digest snooping on a port first before enabling it globally.

■

Digest snooping is unnecessary if the interconnected switches are from the 
same manufacturer.

■

When implementing digest snooping, make sure that the domain 
configurations of the switches of different manufacturers are exactly the same 
to prevent possible broadcast storm caused by otherwise inconsistent mapping 
relationships between VLANs and VPN instances of each switch.

■

If you want to change the configuration of a domain with one or multiple of its 
switches being digest snooping-enabled, be sure to disable digest snooping on 
these switches first to prevent possible broadcast storm caused by otherwise 
inconsistent mapping relationships between VLANs and VPN instances of each 
switch.

■

To enable digest snooping, all ports in an MSTP domain connecting to switches 
coming from other manufacturers must have digest snooping enabled.

■

Do not enable digest snooping on border ports of an MSTP domain.

■

A digest snooping-enabled switch always keeps the latest configuration digests 
it receives. A configuration digest remains valid even if the corresponding port 
goes down.
