EHWIC-ESG-P on 2911 and 1921

bschaper

Level 1

Gurus,

     Ok, I recently recieved the EHWIC so I can eliminate a cheap switch at our remote sites, and have POE as well so I can power the IP phone and camera.  I have installed the card into the router and it has no problems recognizing the card, ports gig 0/0/0 - 0/0/3.  I upgraded to Version 15.2(3)T2 on the router, but still having a couple problems.

1.  I do not have any POE commands

2.  For some reason I cannot get it configured properly

     All I want to do is use it as a switch for the local lan, which is literally a computer, printer, ip phone and camera.  The router has a T1 serial card for access to the network.  No problems with the current config, gig 0/0 lan and serial 0/0/0 is the T1.  How do I go about making all the ports on the EHWIC part of the LAN?

Thanks,

Bryant

It is an expected behavior that when there are no devices plugged into any switch ports that the switch ports will be down and that the Vlan will be down. So if you would be willing to do it, please plug your laptop back in and try the show ip interface brief and show arp again.

Also I wonder if you would check on and report some things to establish what is working and what is not working.

With the laptop connected to a switch port, and from the command line of the router:

- can you ping the laptop?

- can you ping the router gateway at 10.0.0.1?

- can you ping something in the network beyond 10.0.0.1?

then from the laptop:

- can you ping the router Vlan interface at 10.0.200.1?

- can you ping the router interface at 10.0.0.11?

- can you ping the router gateway at 10.0.0.1?

- can you ping anything in the network beyond 10.0.0.1?

And it occurs to me to ask whether the device at 10.0.0.1 has a route to 10.0.200.0?

Do you have the PoE power supply

PWR-2901-POE=   ?

Thanks VMiller,

Nope, not for the 2911.  I was just reading about that.  The 1911 may have just been a firmware version problem, but it recognised the card.

I still can't it to work as a switch though.  It passes traffic and functions fine if I connect everything to the switch, but it does not route any traffic.  Here is a wire of what I would like to accomplish:

T1------>Serial 0/0/0 10.10.10.10---------> Gig 0/0 and Gig 0/0/0-3 Internal LAN 10.0.0.x/24

Then I can get rid of the 5 linksys switch which currently connects to gig0/0.

You have not told us what you have tried to configure. So it is hard for us to figure out why it did not work.

As a start have you configured

interface vlan 1

ip address 10.0.0.1 255.255.255.0

I have tried may things and I am sure I have gone downthe wrong path may times.

If I try assigning an IP to the vlan1 it overlaps with gig0/0 which is on the same subnet.  This is if I remove the IP from gig0/0, I can ping the vlan, but it will not route out gig0/1 to the of the network.

Here is the settings:

Thanks for the additional information. The main issue that I see is that your default gateway statement points to the vlan address

ip default-gateway 10.0.200.1

I would suggest that you change it to

ip default-gateway 10.0.0.1

which would make it agree with the default route that is configured.

Other than this I do not see any particular issues in the config. what address and what default gateway are configured on the devices attached to the switch ports?

No, luck, do I need vlan routing setup as well?

I thought that this ought to have worked. I do notice one change/problem from the config that you posted before. Now both Gig0/0 and Gig0/1 have the same IP address. I would have thought that you would get an error message when you tried to configure this.

Perhaps some additional information might shed some light on this. Would you post the output of show ip protocol, of show ip interface brief, and of show arp?

Also can you confirm for us what is the ip address, what mask, and what gateway configured on a PC connected to a switch port?

Thank-you so much.

Here are the results, but the other router was missing the route, and that fixed the problem instantly.  I guess I am not sure why the other router would have needed it to talk to devices on the gig0/1 interface?  They devices would be on the same subnet, so why did it have to go to the router to talk back to 10.0.0.11?

I can ping the laptop from the router, and the router from the laptop.

Router can ping 10.0.0.11 (local gig0/1) and 10.0.0.10, next hop router

Laptop can ping 10.0.0.11 but not 10.0.0.1

Laptop cannot ping anything on 10.0.0.0/24 besides 10.0.0.11

I am glad that you got it worked out. Thanks for using the rating system to mark this question as resolved. It makes the form more useful when people can read about a problem and can know that an answer was found. Your marking has contributed to this process.

I hope you have already figured it out. But just in case let me make the point that packets from the lap could get anywhere in the network. But that as long as the other router was missing the route to 10.0.200 there was no way for responses to get back to the laptop.
