You can convert a dynamic ICL into a static ICL.
You can update the fabric settings rack-mct-scheme, rack-mct-ports, and rack-ld-mct-ports (with the
definitive set of ports) on an already deployed fabric provided all the racks of the
existing fabric have same ports participating in the ICL or MCT port-channel.
Ensure that the ICL or MCT LLDP ports of all the racks match exactly with the rack-mct-ports and
rack-ld-mct-ports fabric setting.
Shutdown or disable (or lldp disable) the additional LLDP ports followed by fabric configure, and then
re-attempt the dynamic ICL to static ICL conversion. Once the conversion is completed,
bring up the additional LLDP links.
