Hi!!!
I have a problem with ciscocdp on matrix E1. I have a C5 and all is working fine. The same configuration has been configured on E1 series but the cisco 3905 does not get the voice vlan configure on the vvid parameter.

I know that the device is too old...

Anyone knows if there are any problems with the ciscocdp version on enterasys E1 ? The ciscodcp device version is 3.07.32.
 The E1 series have the las firmware version.

Thanks a lot in advance... and sorry for my english

With the understanding that this equipment is no longer supported, but also in recognition that you have submitted this question on behalf of a long-standing customer having diligent service contract coverage for more current equipment, I believe it merits an iteration or two in pursuit of an answer.

If you are comfortable with including the elements of your vlan, ciscodp, policy, and cep configs that relate to what you are trying to do here, I can at least see if they include any obvious flaws.

Thank you.

Hmm, I have a B5 and 3905 that is also having problems getting a voice VLAN (although our other Cisco phones are fine). I'll post my configs soon.

Turns out my problem was an incomplete LLDP configuration, this article had all the required configuration. Also turning off LLDP and letting CiscoDP take priority worked as well.

Thanks James,
the problem in the Matrix E1 is that there is no LLDP. :_(
In A4, B5 and C5 (stackable series) you can configure ciscocdp or lldp. ¿Why you use lldp-med instead ciscocdp? Any adventages?

Thank you for the answer Paul.
James, i have tested de configuration with A-B-C series and all works ok.

Paul, I did the quiestion trying to find a quicky answer with somthing like "E1 ciscocdp version is not compatible with cisco 3905 or modern cisco ipphones".

The configuration is too simple. The voice vlan is 92, and the port in E1 conected to the ipphone has vla 92 tagged.
"show port egress fe.0.1" -> 92 tagged static

I have enabled cdp and ciscocdp in the device and in all the ports.
"show cisco cdp"  ->
Matrix>show ciscodp
CiscoDP : Enabled
Timer : 10
Holdtime (TTL) : 180
Platform : Matrix 1H582-25
Version : 03.07.20
Device ID : 04115622210C
PopulateCDP : Enabled

"show por ciscdp status" ->
Matrix>show port ciscodp info   Port     State    VVID   #Neigh   PDU-TX   PDU-RX  CosExt   TrustExt
 ----------------------------------------------------------------------
   fe.0.1   Enabled    92      0         0        0   undef   trusted
   fe.0.2   Enabled    92      0         0        0   undef   trusted

I have configured the iphone with DHCP and i have the dhcp active and workin ok. I know this because if i configured manually in the ciscophone the vlan-operational then phone catch one ip form the dhcp pool.

Any idea?

My solution is to configure all the phones manually with de vlan operational. But if i want to change the vlan y have to do all again in the 150 ippohnes.

Thanks a lot.

This sample configuration initially uses Profile 1 to assign Priority 3 to all incoming traffic, VLAN-tagged or not. After an IP Phone is detected on a port the E1 uses Profile 2 on that port to communicate (via CiscoDP) the desired Voice VLAN Identifier (VVID) to the IP Phone and treat all of the phone's incoming VLAN-Tagged traffic - identified by means of an IPTOS value of 0x60 (decimal 96) - as Priority 5, while continuing to treat all other traffic (such as untagged traffic from the IP Phone's attached PC) as Priority 3. The IP Phone traffic will thus use Transmit Queue# 2 while all other traffic uses the lower-priority Transmit Queue# 1.

The IP Phone responds to the VVID information by using it in its 802.1Q VLAN Tags and the E1 has been configured to egress that VLAN as Tagged, while the attached PC's traffic remains untagged and is VLAN-assigned based on the port's PVID - which in this configuration remains at its default value of 1, with untagged VLAN 1 egress.

The 5-second CiscoDP timer helps to ensure that the IP Phone knows what VLAN it is supposed to use before it starts sending network traffic, including DHCP. The default timer is 60 seconds.

! priority classification
set priority classification qtagoverride fe.0.1-48 enable [Allow Pri=5 for Tagged traffic]
 
! ciscodp
 set ciscodp timer 5 [Give the phone the VVID ASAP for DHCP]
!
! policy profile
set policy profile 1 "default" disable 0 enable 3 [Force Pri=3 for all traffic]
set policy profile 1 enable [ and enable it]
set policy port fe.0.1-48 1 [Profile 1 is a port-based policy for all]
set policy profile 2 "IP phone" disable 92 enable 3 [Use VVID=92, Force Pri=3 for non-Voice]
set policy profile 2 enable [ and enable it]
set policy classify 2 1 cos 5 iptos 96 [Force Pri=5 if IPTOS=0x60 (Voice)]
!
! cep
set cep enable [Enable Convergence End Point]
set cep port fe.0.1-48 cisco enable [Set all ports to use CEP/CiscoDP]
set cep policy cisco 2 [Use CiscoDP to invoke Profile 2]

Wow!!!
Lot of thanks for the reply.

I can see that in the example you apply de vvid using a policy intead of using de ciscocdp port vvid options...

I will configure it and will post the results.

Hi again!!!
I tried the config, and it didn't work.

The ciscoIpPhone appears un cep info, but the policy doesn't works. The phone does not tag de traffic or the E1 does not classify de traffic into de voip vlan. Am i doing something wrong? The phone port is fe.0.5 and voip vlan-id is 99

Hi!!! finallly I solved de problem :))))

ciscodp , it does not works

The solution is to use only cep and dynamic vlan .

! cepset cep enable
set cep port fe.0.5 cisco enable
set cep policy cisco 1
!
! policy profileset policy profile 1 "voip" enable 99 disable 3
set policy profile 1 enable
!
!
set vlan dynamicegress 99 enable
!


at the moment i cant understand why ciscodp does not works...
