Re: Cannot ping Cisco 877W

Trev1964 · ‎11-14-2017

Hello all, I have been trying to configure a Cisco 877W router so that I can remotely access it via SSH, but I can not seem to get it to work. I have configured an IP address to VLAN 1 and I have even created another VLAN (VLAN 2) to make sure that I have applied an IP address. Every time I try to ping the IP address, I get an error message:

ping 192.168.178.2

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.178.2, timeout is 2 seconds.

Can someone help me with this problem?

Hi Trev,

Are you trying to SSH to the 877 from a remote location or from within the LAN?

Can you share the running config with us?

cheers,

Seb.

Can you just add this command to speed things up a bit:

!
int range fa0-3
  spanning-tree portfast
!

Also to setup SSH:

!
ip domain name <somedomain.com>
!
crypto key generate rsa module 2048
!
ip ssh version 2
!
line vty 0 4
  transport input ssh
!

What is the output from:

sh mac-address dynamic vlan 2

sh ip arp vlan 2

Can you ping your device from the switch?

cheers,

Seb.

hmm ok, which switchport is your device connected to?

sh int status

Trev1964 · ‎11-14-2017

I have two Cisco 3750 switches connected to fa2 and fa3. I have just started studying for the ICND1, so excuse my ignorance.

Trev1964 · ‎11-14-2017

I guess I was wrong about where I connected the switches.

That's fine, they are all access ports and connected to single hosts, not switches, right?? :)

Trev1964 · ‎11-14-2017

The router is connected to two Cisco 3750 switches.

Seb Rupik · ‎11-14-2017

So a 3750 is connected to fa0 ? In which case remove the spanning-tree command

!
int fa0
  no spanning-tree portfast
!

What does the config of the switch connected to Fa0 look like?

cheers,

Seb.

Trev1964 · ‎11-14-2017

I have already set up the router for SSH, that is when I found out that I could not ping the IP address that I assigned. The router will also not allow me to configure an IP address to any of the fa ports. It keeps telling me that:

Trevr1(config-if)#ip address 192.168.178.2 255.255.255.0

% IP addresses may not be configured on L2 links.

Trevr1(config-if)#
