Configuring The Mstp Operation Mode - H3C S5600 SERIES Operation Manual

The port recognizes and sends MSTP packets in legacy format. In this case, the port can only
communicate with the peer through packets in legacy format.
If packets in dot1s format are received, the port turns to discarding state to prevent network storm.
When a port operates in the 802.1s mode:
The port recognizes and sends MSTP packets in dot1s format. In this case, the port can only
communicate with the peer through packets in dot1s format.
If packets in legacy format are received, the port turns to discarding state to prevent network storm.

Configuration example
# Configure GigabitEthernet 1/0/1 to recognize and send packets in dot1s format.
<Sysname> system-view
[Sysname] interface GigabitEthernet 1/0/1
[Sysname-GigabitEthernet1/0/1] stp compliance dot1s
# Restore the default mode for GigabitEthernet 1/0/1 to recognize/send MSTP packets.
[Sysname-GigabitEthernet1/0/1] undo stp compliance

Configuring the MSTP Operation Mode

To make an MSTP-enabled switch compatible with STP/RSTP, MSTP provides the following three
operation modes:
Use the command...
system-view
stp interface interface-type
interface-number
compliance { auto | dot1s |
legacy }
Use the command...
system-view
interface interface-type
interface-number
stp compliance { auto |
dot1s | legacy }
1-21
Remarks
—
Required
By default, a port recognizes and sends
MSTP packets in the automatic mode.
That is, it determines the format of
packets to be sent according to the
format of the packets received.
