Current state
Current physical and administrative state of the serial
interface:
• DOWN (Administratively)—The interface has been shut
down by using the shutdown command.
• DOWN—The serial interface is physically down because
no physical link is present or the link has failed.
• UP—The serial interface is both administratively and
physically up.
Line protocol current state Link protocol state of the serial interface.
Description Description of the serial interface.
Bandwidth Intended bandwidth of the interface.
Maximum Transmit Unit MTU on the serial interface.
Hold timer Interval at which the interface sends keepalive packets.
Internet Address IP address of the serial interface.
Link layer protocol Link layer protocol of the serial interface.
LCP: opened A PPP connection is established successfully.
Output queue - Urgent queuing:
Size/Length/Discards 0/100/0
Output queue - Protocol queuing:
Size/Length/Discards 0/500/0
Output queue - FIFO queuing:
Size/Length/Discards 0/75/0
Information about the urgent, protocol, and FIFO output
queues:
• Size—Number of packets in the queue.
• Length—Maximum number of packets that the queue can
contain.
• Discards—Number of dropped packets.
