    hi,

    I need to support tw voice vlans on aruba switch. Problem is that IPT that needs to get IP from voice vlan 2, gets ip from voice vlan 1. How to force certain voice vlan on port?

    You should have the following in your config:

    CX-6100(config)# vlan 2   
    CX-6100(config-vlan-2)# voice
    CX-6100(config-vlan-2)# vlan 3
    CX-6100(config-vlan-3)# voice
    
    Your config should now look like this:
    
    vlan 2                                                                                                     
        voice                                                      
    vlan 3                                                         
        voice  
    
    Configure your interfaces:
    
    VLAN 1 is being used as an example for your standard data access VLAN. Replace it with whatever you would use for devices that would piggyback off of the phone or whatever you default port VLAN is.
    
    For VLAN 2 VoIP Phone:
    interface 1/1/2
        no shutdown 
        vlan trunk native 1 
        vlan trunk allowed 1,2
        exit
    
    For VLAN 3 VoIP Phone:
    interface 1/1/3
        no shutdown 
        vlan trunk native 1
        vlan trunk allowed 1,3
        exit

    Also, make sure that your phones are showing up with the proper LLDP-MED information for a VoIP phone. If it does not show "voice" under the "Neighbor Med Network Policy" section for entry "Neighbor Med Application type:" then the switch will not put it in the proper VLAN and you will have to do some custom MED assignment stuff.

    Here is an example of an output for a show lldp neigbor-info for a phone connected to port 1/1/3:

    great ... but ... this is exact config I have, and device is getting wrong vlan. I suspect that reason for that is device profile we are using for other reason. So switch is applying device profile VOICE2 for phones that needs this second voice vlan VLAN3. Is there a way to force certain device profile to interface? The only criteria I can use to separate these two phones is mac address ... and mac-group is last criteria used after LLDP and CDP (match platfrom). Becasue LLDP criteria and CDP criteria is the sam for both phones, first one with vlan 2 is used I guess

    What version of AOS-CX are you running on the switch?

    10.11.1010

    You can give this link a look:

    Device fingerprinting commands

    It is applicable to 6200, 6300 & 6400 switch models only.

    I don't have a compatible switch in front of me to offer sample code.

    looks like it is not supported on 6000 series, I do not have client device-finger* cmd, and under device-profile for cdp I can only use platform, sw-version and voice-vlan-query. Mybe I could use syname under LLDP section, but I would need to maintain list of phones for VLAN2 and list for VLAN3 .... admin overhead .... so there is no way to force profile per interface?

    My apologies. I misread your initial posting. 

    That is correct, the 6000 and 6100 do not have the manual profiling or finger printing capabilities.

    Take a look at this document. I know this works on the 6100 but not sure if the capabilities are on the 6000.
