History
Usage
On an MSTP switch, a port configured as an edge port immediately transitions to
Information
the forwarding state. Only ports connected to end-hosts should be configured as
an edge port. Consider an edge port similar to a port with spanning-tree
portfast enabled.
Root guard and loop guard cannot be enabled at the same time on a port. For
example, if you configure loop guard on a port on which root guard is already
configured, the following error message is displayed: % Error: RootGuard is
configured. Cannot configure LoopGuard.
When used in an MSTP network, if root guard blocks a boundary port in the CIST,
the port is also blocked in all other MST instances.
Enabling Portfast BPDU guard and loop guard at the same time on a port results in
a port that remains in a blocking state and prevents traffic from flowing through it.
For example, when Portfast BPDU guard and loop guard are both configured:
•
•

tc-flush-standard

Enable the MAC address flushing after receiving every topology change notification.
Syntax
tc-flush-standard
To disable, use the no tc-flush-standard command.

(OPTIONAL) Enter the keyword edgeport to enable edge
port configuration to move the interface into forwarding
mode immediately after the root fails. Enter the keyword
bpdufilter to stop sending and receiving BPDUs on the
port-fast enabled ports.
(OPTIONAL) Enter the keywords shutdown-on-violation
to hardware disable an interface when a BPDU is received
and the port is disabled.
Enter the keyword rootguard to enable root guard on an
MSTP port or port-channel interface.
Introduced on the MXL 10/40GbE Switch IO Module.
If a BPDU is received from a remote device, BPDU guard places the port in an
err-disabled blocking state and no traffic is forwarded on the port.
If no BPDU is received from a remote device, loop guard places the port in a
loop-inconsistent blocking state and no traffic is forwarded on the port.
