Re: 2901 with HWIC-4ESW-POE

jeremybrainard · ‎11-24-2010

I have a 2901 (config snippets below) with an HWIC-4ESW-POE in Slot 0. I also have other switches down stream off of g0/1. The problem is that I can not get network devices (phones or computers) to work when I plug them in to the HWIC-4ESW-POE in Slot 0. They work fine when I plug them into an actual switch, but will not obtain an IP Address when plugged into the switch module that is in the router. Eventually, these ports will be used for IP Phones and possibly an IP Camera.

I'm sure it's something simple, but it seems I've tried everything I can think of. Thanks in advance!

I'm assuming you are plugging the computer/phone into 0/3/0 as the other ports appear to be shut down. Are VLANs 10 and 50 configured on this device? You can issue "show vlans" to check. Assuming the VLANs are configured, you will need to remove the subinterfaces for Gig0/1 and move this to an SVI config. You can see an example of the config at the link below.

http://www.cisco.rw/en/US/prod/collateral/routers/ps5853/prod_white_paper0900aecd8064c9f4.pdf

Basically, you will have:

interface Vlan10

ip address 10.100.10.1 255.255.255.0

ip nat inside

interface Vlan50

ip address 10.100.50.1 255.255.255.0

ip nat inside

Hope this helps.

jeremybrainard · ‎11-24-2010

Got it...

Never used SVI configs before. Is it similar to using Sub-Interfaces?

You were correct, I did have the VLAN's configured on the router, and I was using Fa0/3/0.

I've adjusted the interfaces (configs below), but I'm still not routing traffic through the router. I can't even ping the switch that's plugged into Gi0/1 at IP Address 10.100.100.15. What should I do with Gi0/1; Does it need an IP Address?

The link you sent was helpful, but slightly cryptic in regards to routing traffic, and actually using SVI.

Thanks Again!

Move the config for gig0/1 to the Vlan1 interface:

interface Vlan1

ip address 10.100.100.1 255.255.255.0

ip nat inside

Brandon

jeremybrainard · ‎11-24-2010

Am I still able to use Gi0/1 to connect to an external switch? or does everything need to be plugged into the HWIC card in Slot 0?

Thanks Again

Brandon Buffin · ‎11-24-2010

You can use gig0/1. You'll want to make it a trunk port if connecting to another switch:

interface gig0/1

switchport trunk encapsulation dot1q
switchport trunk native vlan 1
switchport mode trunk

Make sure the switch on the other side of the port is set to trunk as well.

Brandon

jeremybrainard · ‎11-24-2010

No Luck... Unless I'm missing something, the Switchport command is unavaliable on Gi0/1. Possibly because it's a L3 port? G0/0 and G0/1 are built in to the router.

Brandon Buffin · ‎11-24-2010

Sorry, my mistake. You can either configure the trunk on one of the 4ESW switch ports or reconfigure the subinterfaces such as:

interface GigabitEthernet0/1.10

encapsulation dot1Q 10

ip unnumbered vlan 10

interface GigabitEthernet0/1.50

encapsulation dot1Q 50

ip unnumbered vlan 50

interface GigabitEthernet0/1.100

encapsulation dot1Q 100

ip unnumbered vlan 100

Hope this helps.

Brandon

jeremybrainard · ‎11-24-2010

I used the "ip unnumbered" structure as noted, and the ports on the 4ESW work perfectly. The switch, a 2960 on Gi0/1 is not. Is there any modifications I need to make to the configuration of the switch?
