Configure Stpd Ports Edge-Safeguard Enable - Extreme Networks ExtremeWare XOS Command Reference Manual

ExtremeWare XOS 11.5 supports only the Summit X450 family of switches and the BlackDiamond 8800 series switch.

configure stpd ports edge-safeguard enable

configure stpd <stpd_name> ports edge-safeguard enable <port_list>
Description
Enables the edge safeguard loop prevention on the specified RSTP or MSTP edge port.
Syntax Description
stpd_name
port_list
Default
By default, this feature is disabled.
Usage Guidelines
This command applies only to ports that have already been configured as edge ports.
Loop prevention and detection on an edge port configured for RSTP or MSTP is called "edge
safeguard." You configure edge safeguard on RSTP or MSTP edge ports to prevent accidental or
deliberate misconfigurations (loops) resulting from connecting two edge ports together or by connecting
a hub or other non-STP switch to an edge port. Edge safeguard also limits the impact of broadcast
storms that might occur on edge ports.
An edge port configured with edge safeguard immediately enters the forwarding state and transmits
BPDUs. This advanced loop prevention mechanism improves network resiliency but does not interfere
with the rapid convergence of edge ports.
To view the status of the edge safeguard feature use the
<port_list> {detail}]}
command to display the STPD configuration on the switch, including the enable/disable state for edge
safeguard.
To disable edge safeguard, use one of the following commands:
●
configure stpd <stpd_name> ports edge-safeguard disable <port_list>
●
configure stpd <stpd_name> ports link-type [[auto | broadcast | point-to-point]
<port_list> | edge <port_list> {edge-safeguard [enable | disable]}]
Example
The following command enables edge safeguard on RSTP edge port 4 in STPD s1 on a stand-alone
switch:
configure stpd s1 ports edge-safeguard enable 4
