VoiP phone with 93H or Rap

I'm doing some testing with out Cisco Voip infrastrucutre, an 93H and a RAP3WNP.   If I set the ports, on either device, directly into the VoiP vlan, the Phones work.  No issues.   Now, I'm trying to get the Wired Port on the back of the Phone to work in the data vlan.   So in essence, you would plug the phone in, it would attach to the Voice vlan and the Wired Port on the back of the Voip phone would allow a computer to attach to the Data Network.

 

I've found the instrcutions for doing it on a Mobility Switch:

However, I can't seem to make those work for this setup, which doesn't really surprise me as they're really different products.  Anyway to set a Voip-vlan on these with a Data-Vlan or are they only intended for a single vlan per port?  The Pass-Through port is one solution for the 93H, but I'm more concerned with a RAP scenerio, with no Pass-through available.

 

Has anyone had any success with this on either of these types of devices?  Am i just missing something on the port configs on these devices?  

 

Thanks for any information you can provide.

In the Wired AP profile, you need to set the mode for Trunk, as well as set the switch port mode to trunk, the Trunk Mode Native Vlan, as well as the Trunk mode Allowed VLANs for this to work.

So then the Native Vlan is the Data Vlan? or Voice Vlan?  This works with LLDP-MED?

I tried this, however, the Phone and the Wired port on the Phone, get an IP address in whatever Vlan is set to Native.   Not getting the appropriate seperation.  Any other ideas?

LLDP-MED is passed between the AP and the switch it is connected to.  The AP cannot be configured for LLDP-MED...  Is the switchport on the VLAN that is connected to the Aruba Controller configured for LLDP-MED?  That would be the only chance for that to work in such a fashion.

Re: VoiP phone with 93H or Rap

The switch isn't directly configured for LLDP-MED.  The switch is set as a trunk port with a native vlan specified, a Cisco 37XX series.   I wasn't too concerned about LLDP, was just a question about possibiliites.  

 

I'm more concerend with getting the port on the back of the phone to pick up the data network properly, which I can't seem to get using either trunk mode or access mode.  I'm not sure all the functionality is there on either a Rap or a 93H when compared to a full Access Switch, and I'm thinking that is the issue, as it seems an AP Wired Port profile isn't directly comparable to an Interface or switching Profile, which do not appear to be in the command set for a M3 running 6.1.3.4.  

 

Thoughts?

What is the mechanism used to supply that to the phone internally?  DHCP Option? Static?  CDP?  The RAP should be able to bridge CDP or LLDP med if the port that is connected to the controller is configured for it.

Re: VoiP phone with 93H or Rap

Its currently using CDP.  The controller is directly connected to a Port Channel, with all ports (4) on the same Cisco 6500, varying blades for redundancy.  LLDP is enabled at the Switch level, not on an individual port level.  My current test is using a 93H in CAP mode, not RAP mode.  All traffic is tunneled.   The 93H is currently connected to an edge switch, Cisco as well, with port set in trunk with native vlan, as stated before.  

 

I have a RAP3 that I was going to setup and test this with for Remote Office Purposes, however, I have yet to do that.  

 

I was under the assumption that If I got the proper config setup for CAP mode then I could easily transfer it over to a RAP config without issue, since all the traffic is tunneled.  In a RAP scenerio, for us anyway, the remote office won't have the Cisco equipment in place, only their ISP supplied connection, like a cable modem or DSL Router.   Is this a wrong assessment?

It should work with CAP and RAP mode.  You might want to do a wired port packet Capture to see if the CDP frames are making it out to the 93H wired port.

I can confirm that CDP is working.  I can CDP and see the Phone connected to my Port-Channel.  I can also Show my LLDP neighbords and it shows up there as well.  Doing packet-capture confirms this. However, the phone is still only pulling DHCP from the Trunk Native vlan, not the voice vlan.
