Dell POE with 7941, 7961, 7911 and 7970

[Burgal]

Is there anyone out there running cisco gear on Dell 3448 switches? I just want to see if i'm the only one. I have 9 3448 48 port PoE switches. Using the newer 7941, 7961, 7970 and 7911 phones that all support 802.11af standard PoE compared to the older phones only supporting proprietary cisco PoE.

I don't have my CCM servers fully running yet, so my phones are just sitting there trying to register, which is fine. However I have a handful of phones that lock up after waiting for config for a while. And am wondering if that has anything to do with running on dell gear instead of cisco.

Thanks

btw, I was able to easily add vlan config to my dell switches, and while I was deploying the phones I changed the vlan to the voice one, and I know they can communicate. A lot of poeple said that was hard to do. Only took 30 seconds per phone as I was deploying them.

Just in case anyone asked.

I think you are going to have to go into the phones and program the VLAN information individually. With Cisco PoE, the phones get this info automatically through CDP.
THAT is pain for using Non-Cisco PoE switches not the configuration of the switch.

Oh, I've done that. Just wanted to see if people have been using this scenario, and if they have run into any other troubles other than a lack of cdp.

It probably won't rear its ugly head, but QoS might be another issue. On Cisco switches, you have the capability to trust CoS and trust device cisco-phone. If you have a poorly behaving device on the PC side of the phone that is incorrectly setting a higher CoS value, then you could theoretically run into a situation where that device could steal all of your bandwidth from the phone. But honestly, this is extremely rare.
