Question 5

It was a Saturday morning. You had just been waked up by a pager call about a connectivity problem between a branch router and the head office router. Both routers are connected via a leased line. The link needs to be up 24-hour a day because it carries important financial transactions.

You began your troubleshooting by trying to connect to the branch router using telnet but failed. Fortunately, you managed to connect to a dial up modem attached to the branch router. You did a 'show interface' command on the router. The result is shown below:

  Reserved Conversations 0/0 (allocated/max allocated)

  5 minute input rate 0 bits/sec, 0 packets/sec

  5 minute output rate 0 bits/sec, 0 packets/sec
