Serial1/0/1 current state
Current physical state of the serial interface:
• DOWN (Administratively)—The serial interface was shut
down with the shutdown command, in other words, the
serial interface is administratively down.
• DOWN—The serial interface is physically down (possibly
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.
The Maximum Transmit Unit is 1500, Hold
timer is 10(sec)
The default MTU on the serial interface is 1500 bytes, which
indicates that packets larger than 1500 bytes are fragmented
before being sent. However, if fragmentation is not allowed,
these packets will be dropped.
Hold timer refers to the lifetime of a packet in a network. It is
the maximum amount of time a packet can exist in the network
before being dropped. The hold timer of packets on the serial
interface is set to 10 seconds.
Internet Address is 9.9.9.6/24 Primary IP address of the serial interface.
Link layer protocol is PPP Link layer protocol of the serial interface.
LCP opened, IPCP opened A PPP connection is established successfully.
Output queue : (Urgent queuing :
Size/Length/Discards) 0/100/0
Urgent queuing specifies the current number of packets in the
queue, maximum number of packets that can stay in the
queue, and number of dropped packets.
Link layer protocol packets, such as PPP negotiation packets
and keepalive packets enter this queue.
Output queue : (Protocol queuing :
Size/Length/Discards) 0/500/0
Protocol queuing specifies the current number of packets in the
queue, maximum number of packets that can stay in the
queue, and number of dropped packets.
Packets with IP precedence 6 enter this queue.
