Please help, Router can't ping neither in nor out

[marvick]

I am new to the Cicso router thing, and I am having a problem to connect my testing Cisco router 2501 to the network. My router is connected with a BL50R Tranceiver. The tranceiver is using the default switches setting. My running configuration is as follow:

! NVRAM config last updated at 12:12:22 UTC Thu May 22 2003
Version 11.2
no service password-encryption
no service udp-small-servers
no service tcp-small-servers
!
hostname Earth01
!
enable secret 5 $l$lEPU$OGTUoBsAM60Fx0IVkdExi0
enable password xxxxxxx
!
!
interface Ethernet0
ip address 161.128.191.240 255.255.255.0
no mop enabled
!
interface Serial0
no ip address
shutdown
!
interface Serial1
no ip address
shutdown
!
no ip classless
!
!
line con 0
line aux 0
line vty 0 4
password xxxxxxx
login
!
end

I am not able to ping any host from the router even they are on the same network nor ping the router.

(If I turn on the debug all command, it shows me a lot of traffic running over the network)

Please help.....Thank you very much

Can you paste the output of a "show interface eth0/0"? Also, I assume you aren't having an IP address conflict? Use "show ip arp" to see if it's at least doing an arp on the ip address.

 

[marvick]

This is what I got from using the sh int e0 command:

Ehternet0 is up, line protocol is up

When I do the sh ip arp, i saw results on arp over ip address on the local network.

Thanks for your help...

Hmm, a few errors (but that's probably ok), and it appears to be doing bidirectional traffic so layer1 and 2 seem to be OK.. Is the subnet mask correct for your network? (i.e. the same mask that's configured on all the workstations?).

 

[marvick]

Yes, the router and the workstations are using the same subnet mask.

 

[techkiwi]

There's no routing protocol configured, looking at the config (eg RIP, EIGRP).

Or don't you need it if everything is on the same subnet?

 

[Twinmoon]

Are your work stations able to ping each other? The router?

Debuging your interface might turn something intersting out, but I doubt it considering it's up&up. Try debuging ICMP(and then a few pings) & pasting that up here.

 

[lui3]

this router has obviously worked before. please do the following so that we may troubleshoot this problem further.

clear counters
ping (ip address of hosts on your /24 network)

then

show interface ether 0/0

then paste that output

this will make it easier to determine whether the counters are referencing current problems or some that have just occurred. ie cable problems. thanks

can you also post the

show ip interface ether 0/0

output so that we can see if accesslist or policies are the problem. thanks
