Purpose
Enters administration executive (admin EXEC) mode.
admin
Displays information about the fabric plane.
Verify that the down plane is not administratively down. If the
Admin State is down, the operational state should also be down.

For Cisco CRS-1 Multishelf Systems only.
Displays the contents of the administrative running configuration.
Verify that the plane is set. In the Cisco CRS-1 Multishelf System,
the command output indicates which fiber module in the fabric card
chassis (FCC) is connected from the plane.
The following is an example of the output:
controllers fabric plane 0 topology single-module location
F0/SM4/FM
If the plane is administratively down and the only flag is P,
bring the plane up. Proceed to
the "Understanding the Flags Field" section on page 4-113
detailed information on flags.
If the plane is administratively up but the flag is m, the plane is
multicast down and some destinations (for example, MSCs and
route processors) are having connectivity issues to the fabric on
that plane. Proceed to Step
Field" section on page 4-113
If the plane is administratively down and the flag is p, the plane
is operationally down. Proceed to
"Understanding the Flags Field" section on page 4-113
detailed information on flags.
configure—Enters administration configuration mode
no controllers fabric plane plane-id shutdown—Performs a
graceful shutdown of the fabric plane to ensure that data is no
longer flowing through the plane before a fabric
reconfiguration or fabric plane migration
end—Saves the configuration change
