Redistributing the Links

When you provision the Fabric Extender with statically pinned interfaces, the downlink host interfaces on the
Fabric Extender are pinned to the fabric interfaces in the order they were initially configured. If you want to
maintain a specific relationship of host interfaces to fabric interface across reboots, you should repin the links.
You may want to perform this function in these two situations:
• A change in the max-links configuration.
• If you need to maintain the pinning order of host interfaces to fabric interfaces.

Changing the Number of Links

If you initially configured a specific port on the parent switch, for example port 33, as your only fabric interface,
all 48 host interfaces are pinned to this port. If you provision another port, for example 35, then you must
enter the pinning max-links 2 command to redistribute the host interfaces. All host interfaces are brought
down and host interfaces 1 to 24 are pinned to fabric interface 33 and host interfaces 25 to 48 are pinned to
fabric interface 35.
