Identifying and Resolving Generic Router Problems
247
Turn up interface Serial 0/0.
With the proposed solutions, the only thing left is to implement them and
see if they work, as follows:
Router_A#
conf t
Enter configuration commands, one per line. End with CNTL/
Z.
Router_A(config)#
interface ethernet 0/0
Router_A(config-if)
#ip address 172.16.10.1 255.255.255.0
Router_A(config-if)#
interface serial 0/0
Router_A(config-if)#
no shut
172.16.20.5 overlaps with Ethernet0/1
Serial0/0: incorrect IP address assignment
Router_A(config-if)#
^Z
Router_A#
It looks as if the Ethernet 0/0 interface is still not functional. We still need
to check the cable and transceiver to try to isolate a physical problem. You
test the cable and it is working properly so you swap the transceiver. Now
let's check the interface status:
Ethernet0/0 is up, line protocol is up
Hardware is AmdP2, address is 0010.7bd9.2880 (bia
0010.7bd9.2880)
MTU 1500 bytes, BW 10000 Kbit, DLY 1000 usec, rely
128/255, load 1/255
Encapsulation ARPA, loopback not set, keepalive set
(10 sec)
ARP type: ARPA, ARP Timeout 04:00:00
Last input never, output 00:00:05, output hang never
Last clearing of "show interface" counters never
Queueing strategy: fifo
Output queue 0/40, 0 drops; input queue 0/75, 0 drops
5 minute input rate 509000 bits/sec, 215 packets/sec
5 minute output rate 1167000 bits/sec, 315 packets/sec
12900 packets input, 10324500 bytes, 0 no buffer
Received 235 broadcasts, 0 runts, 0 giants, 0
