Enabling PVST filtering on a port
HP Switch(config)#: spanning-tree 8 pvst-filter Warning: The BPDU filter allows the port to go into a continuous forwarding mode and spanning-tree will not interfere, even if the port would cause a loop to form in the network topology. If you suddenly experience high traffic load, disable the port and reconfigure the BPDU filter with the CLI command(s): "no spanning-tree PORT_LIST bpdu-filter" "no spanning-tree PORT_LIST pvst-filter"
Syntax:
Configures the duration of time protected ports remain disabled. The default value of
0
sets an infinite timeout, so ports that are disabled are not re-enabled automatically.
NOTE: This is a GLOBAL command.
Range: 0 - 65535 seconds; Default: 0
You can also set the timeout in the MIB with this MIB object:
hpSwitchStpBpduProtectionTimeout
It is also possible to use the following automatic re-enable timer command:
HP Switch(config)#: spanning-tree bpdu-protection-timeout 120
