system-view [Sysname] irf domain 30 irf link-delay Syntax irf link-delay interval View undo irf link-delay System view Default level 3: Manage level Parameters interval: Sets the IRF link down report delay in milliseconds. The value range is 0 to 30000. If your IRF fabric requires a fast master/subordinate or IRF link switchover or has deployed the BFD or GR feature, HP recommends setting the delay to zero seconds. Description Use irf link-delay to set the delay for the IRF ports in the IRF fabric to report a link down event. Use undo irf link-delay to restore the default. By default, if an IRF link changes from up to down, the IRF port immediately reports the event to the IRF fabric. An IRF link down report delay helps avoid link flapping causing frequent IRF splits and merges during a short time. An IRF port handles link down and link up events, as follows: • When the IRF link changes from up to down, the port does not immediately report the change to the IRF fabric. If the IRF link state is still down when the delay time is reached, the port reports the change to the IRF fabric. • When the IRF link changes from down to up, the link layer immediately reports the event to the IRF fabric. Examples # Set the IRF link down report delay to 300 milliseconds. system-view [Sysname] irf link-delay 300 irf mac-address persistent Syntax irf mac-address persistent { always | timer } View undo irf mac-address persistent System view 9
