Stp Config-Digest-Snooping - 3Com S7906E Command Reference Manual

port leaves the aggregation group. For detailed information about link aggregation, refer to Link
Aggregation Configuration in the Access Volume.
If the mode is set to auto on a port, the port automatically recognizes and resolves the received
compatible-format
compatible-format or 802.1s-compliant BPDUs.
If the mode is set to legacy or dot1s on a port, the port can only receive and send BPDUs of the
specified format. If the port is configured not to detect the packet format automatically while it works
in the MSTP mode, and if it receives a packet in the format other than the configured format, it will
become a designated port and remain in the discarding state to prevent the occurrence of a loop.
Examples
# Configure Ethernet 1/1 to receive and send only standard-format (802.1s) MSTP packets.

[Sysname-GigabitEthernet2/0/1] stp compliance dot1s
