Configuring Stacking Ports in a Live Environment
You can use the
multi-stack-port command (similar to the
multi-stack-trunk command) to change a live stack-trunk to a stack-port. The
no multi-stack-port command removes a live stack link.
The following example replaces two live stack-trunks with a stack-port on both units.
ICX7650-48ZP Router# configure terminal ICX7650-48ZP Router(config)# stack unit 1 ICX7650-48ZP Router(config-unit-1)# multi-stack-port 1/3/1 and 2/3/1 ICX7650-48ZP Router(config-unit-1)# multi-stack-port 1/3/3 and 2/3/3 ICX7650-48ZP Router(config-unit-1)# end ! ! ICX7650-48ZP Router#

Note: Both the
multi-stack-trunk and the
multi-stack-port commands perform numerous checks to make sure no unit would become unreachable. However,
the checks have limitations. Verify the physical connections with the
show stack connection command, and make sure that reducing or removing stack-ports or stack-trunks will
not break the stack.
