set spantree lpcapablepartner

Use this command to specify per port whether the link partner is Loop Protect capable.

Syntax

set spantree lpcapablepartner port-string {true | false}

Parameters

port-string Specifies port(s) for which to configure a Loop Protect capable link partner. For a detailed description of possible port-string values, refer to Port String Syntax Used in the CLI in the S-, K-, and 7100 Series Configuration Guide.
true | false Specifies whether the link partner is capable (true) or not (false).

Defaults

None.

Mode

All command modes.

Usage

The default value for Loop Protect capable partner is false. If the port is configured with a Loop Protect capable partner (true), then the full functionality of the Loop Protect feature is used. If the value is false, then there is some ambiguity as to whether an Active Partner timeout is due to a loop protection event or is a normal situation due to the fact that the partner port does not transmit Alternate Agreement BPDUs. Therefore, a conservative approach is taken in that designated ports will not be allowed to forward unless receiving agreements from a port with root role.

This type of timeout will not be considered a loop protection event. Loop protection is maintained by keeping the port from forwarding but since this is not considered a loop event it will not be factored into locking the port.

Refer to the S-, K-, and 7100 Series Configuration Guide for more information.

Example

This example shows how to set the Loop Protect capable partner to true for ge.1.1:

System(rw)->set spantree lpcapablepartner ge.1.1 true
