Cisco ISR 2951 with ES3-24p module

[jotbarkis]

Hello everyone,

I am fairly new to Cisco and network configs, and have a question regarding the mentioned products.

I would like to setup a router on a stick with the 2951 router and the ES3 module acting as a switch. 

Situation: 1 pc, 1 server connected to the ES3 module, the module itself is connected internally through 0/25 0/26 ports (if I am correct?) to the router. I want to create several vlans assigned to specific ports on the module.

I have tried to do this by myself, with no luck so far. What I did:

On the router created a 1/0.10 interface, IP 192.168.10.1, encapsulation dot1q

On the switch int 0/26 made it as a trunk port, assigned vlan 10

Gi0/1-4 interfaces assigned to vlan 10

Currently the vlan 10 interface has an IP of 192.168.10.2

From the PC (IP 192.168.10.5) I can ping 10.1 and 10.2, but I cannot ping the server 10.25 (same from the server, PC not pingable)

Is there some sort of setting I am missing, or is this the wrong approach?

You did not say where the server is connected? Is it connected on the same vlan?

Which network mask are you using?

[jotbarkis]

Yes, the server is in the same vlan.

Masks are 255.255.255.0 everywhere I think. 

[Flavio Miranda]

Should be pinging. Does your server can reply ping?  Isn´t there any firewall enable on server?

[jotbarkis]

I will have to check the firewall, but I tried to use a regular pc instead
of the server in the same port, didn't ping.

[Flavio Miranda]

Both server and PC interface are on the same vlan right?

Can you share the show run ?

[jotbarkis]

Yes, the interfaces are Gi0/1 and Gi0/2, both assigned to vlan 10.

I will try to hook up a seperate switch, perhaps there is an issue with the
Es3 module itself?

[Flavio Miranda]

Well, that could be. If you have two interfaces and both are on the same vlan and PCs are configured with static IP address on the same network, then you need to ping each other. Pretty basic stuff. 

I´d like to see some output from the module like:

show run-config

show int status

show run int  Gi0/1

show run in  Gi0/2

[jotbarkis]

Attached output of following commands, I see the port status as notconnect, I guess that is where my issue is.

The cables are good and they are physically connected to those ports.

The (IMHO) non-intuitive thing about these sort of etherswitch modules is that the router is the physical home and power supply to the switch, but they are devices with separate configs and software. The etherswitch module also probably has more routing throughput than the 2951 if has L3 routing available. This is what a SM-ES2-16-P installed in a 2951 looks like in my lab. Here is the 2951 side.

In practical terms, that means the router port G2/0 connects to switch port G0/18 and router port G2/1 connects to switch port switch port G0/17 without a patch cord. Hopefully that helps you understand the devices interconnect.
