I bypassed the 3550 and just put a repeater in between the cable modem and equipment which allowed me to pull the addresses on to my equipment. Ultimately the issue seems to be with my 3550, either configuration issue or possible code issue, nevertheless something I need to resolve

Correction guys, what I stated is that I can not pull an IP address on the vlan interface as imbadatthis did on his output. It does not work whether I use 1 or all the ports. fast0/48 <<<- I plugged either into the wireless or the cable modem for testing fast0/46 <<<- Connection from my...

I tried the shut and no shut, however I still get the same result. I also rebuilt it all with the vlan being activated first prior to adding the the client command to the vlan. I am thinking that there is a another issue with the DHCP on the device. ###################### here is an output i...

ok I managed to get my firewall to pull a dynamic ip through the vlan from my wireless router as a test. Now what I need to understand is that you managed to pull dynamip IP to your vlan23 that you pasted in one of your post. would you mind pasting your config, so I can see if I am missing...

imbadatthis, man I attempted the whole thing all over again, and even erased the running config and started fresh without any trace of the dhcp snooping items. I ten created the vlan, then created the vlan interface and added the dhcp setting to it. I then edited the fastE port and added to...

Ok I see what your seeing, and so I removed the snooping configuration on the box. Now I'm trying to rebuild the vlan and add all associated interfaces afterward. let me see how it goes.

No I actually added the command to the vlan interface prior to activating the vlan. I then added the fastE to the vlan, yet still no success. I keep getting this in the debug output "B'cast on Vlan6 interface from 0.0.0.0%Unknown DHCP problem.. No allocation possible" Below is the running...

Ok I started everything from scratch, and have the config show as below. I did as you stated but still no DHCP allocation. To test it properly and make sure it was not an issue wit my cable/ISP, I plugged the 3550 into my wireless with the following config to see if it will pull an IP. It was...

Well, I would say then that the authentication would involve the cable modem and not any edge device i connect to it. I identified earlier that my wireless pulled an IP without issue, and I can do the same with any port on the 3550 that does not belong to a vlan.

Yes that is correct those are the assigned ports and the devices are configured for DHCP addressing. And yes vlan6 does show as up up.

The switch interface configs are sow before your post via my last post. also the connection to the ISP is through the cable modem, which basically works like this. A request goes out to the ISP's DHCP server via the cable modem and once and an IP is assigned. previously I had my wireless...

imbadatthis, yes I do have an isp and am being provided multiple IP's. I do have the minimum config as identified, however I am unable to pull an IP on any the devices I plug into any of the ports under the vlan. I pasted a copy of my config below, I am able to get it to work on any port outside...

Not sure what you mean by "UNTAGGED". But I am only using the one VLAN and have not created a trunk of any kind. I'm mainly trying to pull DHCP address through that VLAN. As far as the the terminating connection to the ISP can you elaborate on what you mean.

Hi all, I have an issue, and need some assistance with solving it. I am attempting to use a Vlan as for public DHCP via my ISP. I have multiple IP's from ISP and would like use that VLAN as sort of a dump switch per say. For better understanding here is my setup. I created Vlan6 on my...
