R2511-HP MSR Router Series Interface Command Reference(V5)

93
Field Description
Output:189 packets, 210072 bytes
0 errors, 0 underruns, 0 collisions
0 deferred
Sent statistics on the cellular interface:
• errors—Number of error packets detected at the physical
layer.
• underruns—Number of packets that fail to be forwarded
because the serial interface reads from memory at a slower
speed than it forwards packets.
• collisions—Number of packets with collisions detected.
• deferred—Number of deferred or timeout packets.
The brief information of interface(s) under
route mode:
Brief information about Layer 3 interfaces.
Link: ADM - administratively down; Stby -
standby
Link status:
• ADM—The interface has been administratively shut down.
To recover its physical state, use the undo shutdown
command.
• Stby—The interface is operating as a backup interface. To
see the primary interface, use the display standby state
command in High Availability Command Reference.
Protocol: (s) - spoofing
If the network layer protocol state of an interface is shown as
UP, but its link is an on-demand link or not present at all, its
protocol attribute includes the spoofing flag (an s in
parentheses).
Interface Abbreviated interface name.
Link
Physical link state of the interface:
• UP—The link is up.
• ADM—The link has been administratively shut down. To
recover its physical state, use the undo shutdown
command.
Protocol
Protocol connection state of the interface, which can be UP,
DOWN, or UP(s).
Main IP Main IP address of the interface.
Description Description of the interface.
Cause
Cause of a DOWN physical link. If the port has been shut
down with the shutdown command, this field displays
Administratively. To restore the physical state of the interface,
use the undo shutdown command.
display interface cellular-ethernet
Use display interface cellular-ethernet to display information about cellular Ethernet interfaces.
