Configure Stpd Ports Link-Type - Extreme Networks ExtremeWare XOS Command Reference Manual

STP Commands

configure stpd ports link-type

configure stpd <stpd_name> ports link-type [auto | edge | broadcast |
point-to-point] <port_list>
Description
Configures the ports in the specified STPD as auto, edge, broadcast or point-to-point link types.
Syntax Description
stpd_name
auto
edge
broadcast
point-to-point
port_list
Default
All ports are broadcast link types.
Usage Guidelines
If your STPD has the same name as another component, for example a VLAN, Extreme Networks
recommends that you specify the identifying keyword as well as the name. If your STPD has a name
unique only to that STPD, the keyword
The default, broadcast links, supports legacy STP (802.1D) configurations.
If you configure a port to be an edge port, the port immediately enters the forwarding state. Edge ports
remain in the forwarding state unless the port receives a BPDU. In that case, edge ports enter the
blocking state.
RSTP does not send any BPDUs from an edge port nor does it generate topology change events when
an edge port changes its state.
RSTP rapidly moves the designated ports of a point-to-point link type into the forwarding state. This
behavior is supported by RSTP only.
An auto link behaves like a point-to-point link if the link is in full duplex mode or if link aggregation is
enabled on the port; otherwise, an auto link behaves like a broadcast link. If a non-STP switch exists
between several switches operating in 802.1W mode with auto links, the non-STP switch may negotiate
full-duplex even though the broadcast domain extends over several STP devices.
508
Specifies an STPD name on the switch.
Specifies the switch to automatically determine the port link type. An auto link
behaves like a point-to-point link if the link is in full-duplex mode or if link
aggregation is enabled on the port. Used for 802.1W configurations.
Specifies a port that does not have a bridge attached. An edge port is placed
and held in the STP forwarding state unless a BPDU is received by the port.
Used for 802.1W configurations.
Specifies a port attached to a LAN segment with more than two bridges. Used
for 802.1D configurations. A port with broadcast link type cannot participate in
rapid reconfiguration. By default, all ports are broadcast links.
Specifies a port attached to a LAN segment with only two bridges. A port with
point-to-point link type can participate in rapid reconfiguration. Used for
802.1W configurations.
Specifies one or more slots and ports. May be in the form 2:*, 2:5, 2:6-2:8.
