set spantree lpcapablepartner port-string { true | false }
Syntax Description
Command Defaults
None.
Command Type
Switch command.
Command Mode
Read-Write.
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.
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 Section 4.1.1 .
true | false Specifies whether the link partner is capable (true) or not
(false).
