Description: Congure the port-specic parameters of the spanning
tree protocol for individual ports.
Parameters:
o admin-edge-port - Applies only to RSTP/MSTP. When correctly set for each
port it improves the protocol operation. Indicate whether the port is
connected to LAN segment that doesn't have any bridge or switch
connected to it. If a bridge or switch is detected on the segment,
the port will automatically operate as if Edge = 'No' has been set.
o auto-edge-port - Applies only to MSTP. Used to set the automatic edge
port detection.
o mcheck - Applies only to RSTP/MSTP. Forces the Port Protocol Migration
state machine to transmit RST or MST BPDUs for a Migrate Time period
to test whether all STP Bridges on the attached LAN have been removed
and the port can continue to transmit RST or MST BPDUs. Setting mcheck
has no effect if the Bridge is operating in STP Compatibility mode.
o path-cost <1-65535> or <1-200000000> or <auto> - Individual port cost -
used to determine which ports are forwarding ports.
Can be set to 'auto' or congured by a user. A value of 'auto' (default)
indicates the link speed determines the cost value. The following ranges
are available for user conguration:
For RSTP/MSTP: 1 through 200000000 (recommended value is 2000000 for
Ethernet and 10/100TX ports operating at 10 Mbps; 200000 for 10/100TX
ports operating at 100 Mbps and 100FX; 20000 for 1000SX, 1000LX,
1000Stk, 1000T ports).
For STP: 1 through 65535 (recommended value is 100 for Ethernet and
10/100TX ports operating at 10 Mbps; 10 for 10/100TX ports operating
at 100 Mbps and 100FX; 5 for 1000SX, 1000LX, 1000Stk, 1000T ports).
o pvst-lter (default: off) - On/off control to ignore a port's
incoming per-VLAN spanning tree (PVST) BPDU packets.
o pvst-protection (default: disabled) - Enable/Disable per-VLAN
spanning tree (PVST) protection on port(s). If pvst-protection
is enabled on specied port(s) and if the port(s) receive
PVST BPDU packets then the port(s) will be disabled
If enabled, this takes precendence over the pvst-lter
conguration for a port. o root-guard - Applies only to MSTP. If TRUE causes
the port not to be
selected as Root Port for the CIST or any MSTI.
o tcn-guard - Applies only to MSTP. If TRUE causes the port not to
propagate received topology notications and topology changes to
other ports.
o bpdu-lter (default: off) - On/off control to ignore a port's
incoming spanning-tree BPDU packets and prevent sending any.
o bpdu-protection (default: disabled) - Enable/Disable STP BPDU
protection on port(s). If bpdu-protection is enabled on specied
port(s) and if the port(s) receives spanning-tree BPDU packets then
the port(s) will be disabled.
o point-to-point <true|false|auto> (default: auto) - Applies only to
