Description
Data link layer protocol state of the interface:
•
UP—The data link layer protocol of the interface is up.
•
DOWN—The data link layer protocol of the interface is down.
•
UP(s)—The data link layer protocol of the interface is up, but the
link is an on-demand link or does not exist. The (s) attribute
represents the spoofing flag. This value is typical of null interfaces
and loopback interfaces.
Primary IP address of the interface. This field displays two hyphens (--)
if the interface does not have an IP address.
Description of the interface.
Brief information about Layer 2 interfaces.
Link type options for interfaces.
Speed of the interface, in bps.
This field displays the (a) flag next to the speed if the speed is
automatically negotiated.
This field displays auto if the interface is configured to autonegotiate its
speed but the autonegotiation has not started.
Duplex mode of the interface:
•
A—Autonegotiation. The interface is configured to autonegotiate
its duplex mode but the autonegotiation has not started.
•
F—Full duplex.
•
F(a)—Autonegotiated full duplex.
•
H—Half duplex.
•
H(a)—Autonegotiated half duplex.
Link type of the interface:
•
A—Access.
•
H—Hybrid.
•
T—Trunk.
Port VLAN ID.
Cause for the physical link state of an interface to be DOWN:
•
Administratively—The interface has been manually shut down
by using the shutdown
of the interface, use the
•
DOWN ( Link-Aggregation interface down )—The interface is a
member port of an aggregate interface, and the aggregate
interface is down.
•
DOWN (Loopback detection down)—The loopback detection
module has detected loops.
•
DOWN ( Monitor-Link uplink down )—The monitor link module
has detected that the uplink is down.
•
Not connected—No physical connection exists (possibly
because the network cable is disconnected or faulty).
•
Storm-Constrain—The storm control feature has 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.
