Usage Guidelines
errdisable recovery [cause
bpduguard |interval
<10-1000000>]
• Disables error
• recovery – Enables the timeout mechanism for a port to be
recovered
• cause bpduguard – Specifies the reason for errdisable
• bpduguard – Recovers from errdisable due to bpduguard
• interval <10-1000000> – Specifies the interval after which a port
is enabled
• <10-1000000> – Specifies an errdisable-timeout interval in
seconds.
mst [<0-15> priority

forward-time <4-30> |hello-time
<1-10>|instance
<1-15>|max-age <4-60> |
max-hops <7-127>|region
<LINE>|revision <0-255>]
Configures multiple spanning tree commands
• <0-15> – Specifies the number of instances required for
configuration
• priority <0-61440> – Sets the bridge priority for an instance to
the value specified. Use the no parameter with this command to
restore the default bridge priority value
• <0-61440> – Bridge priority in increments of 4096 (Lower
priority indicates greater likelihood of becoming root)
• cisco-interoperability [enable|disable] – Enables/disables CISCO
interoperability
• Enable – Enables the multiple spanning tree protocol
• forward-time <4-30> – Specifies the forwarding delay time in
seconds between 4 -30
• hello-time <1-10> – Specifies the hello BDPU interval in seconds
within the range 1-10
• Instance <1-15> – Defines the instance ID to which the VLAN is
associated
• max-age <4-60> – Maximum time to listen for the root bridge in
seconds. Enter a value between 4 and 60
• max-hop <7-127> – Maximum hops when BPDU is valid
• region <LINE> – MST region
• revision <0-255> – Sets the revision number of the MST bridge.
• <0-255> – Defines the revision number for configuration
information
portfast [bpdufilter| bpduguard]
default
Enables the portfast feature on a bridge
• bpdufilter default – Use the bpdu-filter command to set the BPDU
filter for the port. Use the no parameter with this command to
revert the port BPDU filter value to the default value.
The Spanning Tree Protocol sends BPDUs from all ports. Enabling
the BPDU Filter feature ensures PortFast enabled ports do not
transmit or receive BPDUs
• bpduguard default – Guards portfast ports against BPDU receive
• default – Enables the BPDU filter on portfast enabled ports by
default
