If the stp no-agreement-check command is used on an interface, the interface can perform fast
state transition without the Agreement messages.

8.4.7 Checking the Configuration

Procedure
Step 1 Run the display stp [ instance instance-id ] [ interface { interface-type interface-number [ to
interface-number ] }&<1-10> ] [ brief ] and display stp [ instance instance-id ] [ slot slot-id ]
[ brief ] command to check the state and statistics of a spanning tree.
----End
Example
Run the display stp command, and you can view the Hello time, forward delay, and max age
of the spanning tree, maximum number of hops in the MST region, STP convergence mode of
the specified port, link type of the port, maximum number of BPDUs that the port sends within
each Hello time, format of the MSTP packets sent and received on the port, and whether digest
snooping is configured. The following is an example:
<Quidway> display stp instance 0 interface gigabitethernet 1/0/0

NOTE
Config-digest-snoop, which indicates whether digest snooping is configured, is displayed only if you have
run the stp config-digest-snoop command. If the stp config-digest-snoop command is not run, Config-
digest-snoop is not displayed after you run the display stp command.
