Troubleshooting the Global Registrations for the Interface Manager Distributor
The show imds registrations command is used to display the information for the IMD client
registrations.
IMD supports the concept of an encapsulation change registration so that clients are informed of the
changes on an interface.
The following sample output from the show imds registrations command with the all keyword shows
all the IMD registrations:
RP/0/RP0/CPU0:router# show imds registrations all location 0/0/CPU0
IMD REGISTRATIONS
Reg: C - Create, E - Encap, M - MTU, S - State
