IP ADDRESS DHCP not working

[user123]

Hi,
Iam trying to get my cable modem to issue my router an IP address.

Iam using IOS 12.1(T).

I used the command IP ADDRESS DHCP and it still will not get an address. I used different mac address' from various PC's but that didnt solve the problem.

Router#sho int e0
Ethernet0 is up, line protocol is up
Hardware is Lance, address is 0000.2c31.57dc bia 0000.0d31.s6dc)
Internet address will be negotiated using DHCP <-- Problem
MTU 1500 bytes, BW 10000 Kbit, DLY 1000 usec,
reliability 199/255, txload 1/255, rxload 1/255
Encapsulation ARPA, loopback not set
Keepalive set (10 sec)
ARP type: ARPA, ARP Timeout 04:00:00
Last input 00:00:05, output 00:00:07, output hang never
Last clearing of &quot;show interface&quot; counters never
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0
Queueing strategy: fifo
Output queue :0/40 (size/max)
5 minute input rate 1000 bits/sec, 1 packets/sec
5 minute output rate 0 bits/sec, 0 packets/sec
400 packets input, 29335 bytes, 0 no buffer
Received 346 broadcasts, 0 runts, 0 giants, 0 throttles
0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored
0 input packets with dribble condition detected
390 packets output, 32190 bytes, 0 underruns
70 output errors, 0 collisions, 52 interface resets
0 babbles, 0 late collision, 0 deferred
70 lost carrier, 0 no carrier
0 output buffer failures, 0 output buffers swapped out


This is what it stays at. Never gets an ip address.
**Internet address will be negotiated using DHCP **

Anyone else experience this or is my router garbage?
Thanks in advance for any input.

For anyone that will read this in the future and had the same problem:

A simple modem reset did the trick.

I think last post could be the answer. I have had this same situation. I finally reset my cable modem and then was able to get an IP via DHCP.
