configure stpd ports link-type
configure stpd <stpd_name> ports link-type [[auto | broadcast | point-to-
point] <port_list> | edge <port_list> {edge-safeguard [enable | disable]}]
Description
Configures the ports in the specified STPD as auto, broadcast, edge, or point-to-point link types.
Syntax Description
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
stpd
is optional.
The default, broadcast links, supports legacy STP (802.1D) configurations. If the switch operates in
802.1D mode, any configured port link type will behave the same as the broadcast link type.
RSTP rapidly moves the designated ports of a point-to-point link type into the forwarding state. This
behavior is supported by RSTP and MSTP only.
In an MSTP environment, configure the same link types for the CIST and all MSTIs.
stpd_name
Specifies an STPD name on the switch.
auto
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.
broadcast
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 using RSTP or MSTP. By default, all ports are broadcast
links.
point-to-point
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 and MSTP configurations
port_list
Specifies one or more ports or slots and ports.
edge
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 and MSTP configurations.
edge-safeguard
Specifies that the edge port be configured with edge safeguard, a loop
prevention and detection mechanism. Used for 802.1w and MSTP
configurations
enable
Specifies that edge safeguard be enabled on the edge port(s).
disable
Specifies that edge safeguard be disabled on the edge port(s).
