Table 4 Command output
Field Description
Current state
Physical link state of the interface:
• Administratively DOWN—The interface has been shut
down by using the
shutdown command.
• DOWN—The interface is administratively up, but its physical
state is down (possibly because no physical link exists or the
link has failed).
• DOWN ( Link-Aggregation interface down )—The
aggregate interface to which the interface belongs has been
shut down by using the
shutdown command.
• mac-address moving down—The interface has been shut
down by the MAC address move suppression feature.
• MAD ShutDown—The interface has been shut down by
IRF MAD. This state occurs if the interface is on an IRF
fabric placed in Recovery state after an IRF split.
• OFP DOWN—The interface has been shut down by
OpenFlow.
• Storm-Constrain—The interface has been shut down
because the storm control feature detected that unknown
unicast traffic, multicast traffic, or broadcast traffic exceeded
the upper threshold.
• STP DOWN—The interface has been shut down by the
BPDU guard feature.
• UP—The interface is both administratively and physically
up.
Line protocol state
Data link layer state of the interface. The state is determined
through automatic parameter negotiation at the data link layer.
• UP—The data link layer protocol is up.
• UP (spoofing)—The data link layer protocol is up, but the
link is an on-demand link or does not exist. This attribute is
typical of null interfaces and loopback interfaces.
• DOWN—The data link layer protocol is down.
• DOWN
(protocols)—The data link layer has been shut
down by protocols included in the parentheses. Available
protocols include:
{ DLDP—Shuts down the data link layer when it detects
that the link is unidirectional.
{ OAM—Shuts down the data link layer when it detects a
remote link failure.
{ LAGG—Shuts down the data link layer when it detects
that the aggregate interface does not have Selected
ports.
{ BFD—Shuts down the data link layer when it detects a
link failure.
Bandwidth Expected bandwidth of the interface.
Maximum transmission unit MTU of the interface.
