Stp Ignored Vlan - HP 12500 Series Command Reference Manual

Usage guidelines
If a port on a device running MSTP or RSTP connects to an STP device, this port automatically
transitions to the STP mode when the port receives STP BPDUs. However, if the peer STP device is
shut down or removed and the local device cannot detect the change, the local device cannot
automatically transition back to the original mode. In this case, you can perform an mCheck
operation to forcibly transition the port to operate in the original mode.
The device operates in STP, RSTP, or MSTP mode depending on the spanning tree mode setting.
The stp global mcheck command is effective only when the device operates in MSTP or RSTP
mode.
Examples
# Perform mCheck globally.
<Sysname> system-view
[Sysname] stp global mcheck
