spanning-tree pvst err-disable
c e s
Place ports in an err-disabled state if they receive a PVST+ BPDU when they are members an untagged
VLAN.
Syntax
spanning-tree pvst err-disable cause invalid-pvst-bpdu
Defaults
Enabled; ports are placed in err-disabled state if they receive a PVST+ BPDU when they are members
of an untagged VLAN.

Information
Some non-Dell Force10 systems that have hybrid ports participating in PVST+ transmit two kinds of
BPDUs: an 802.1D BPDU and an untagged PVST+ BPDU.
Dell Force10 systems do not expect PVST+ BPDU on an untagged port. If this happens, FTOS places
the port in error-disable state. This behavior might result in the network not converging. To prevent
FTOS from executing this action, use the command
no spanning-tree pvst err-disable cause
invalid-pvst-bpdu
.

Commands
tc-flush-standard
c e s

To disable, use the
no tc-flush-standard
command.
Defaults
Disabled

CONFIGURATION

History
Usage
Information
By default FTOS implements an optimized flush mechanism for PVST+. This helps in flushing the
MAC addresses only when necessary (and less often) allowing for faster convergence during topology
changes. However, if a standards-based flush mechanism is needed, this
knob
command can be turned
on to enable flushing MAC addresses upon receiving every topology change notification.
