Configuring No Agreement Check - HP 5820X series Configuration Manual

As shown in Figure
Device A and Device B connect to Device C, which is a third-party device. All these devices are in
•
the same region.
Enable digest snooping on Device A's and Device B's ports that connect Device C, so that the three
•
devices can communicate with one another.

Configuring no agreement check

In RSTP and MSTP, the following types of messages are used for rapid state transition on designated ports:
Proposal: sent by designated ports to request rapid transition
•
Agreement: used to acknowledge rapid transition requests
•
Both RSTP and MSTP devices can perform rapid transition on a designated port only when the port
receives an agreement packet from the downstream device. RSTP and MSTP devices have the following
differences:
