VoIP configuration on HP 5120 EI switches (Alcatel IP phones)

Hi,

 

we have HP 5120 EI switches configured for Alcatel VoIP phones. Anyone with the same setup? I want to compare the configurations in use on the field:

 

voice vlan mac-address 0080-9f00-0000 mask ffff-ff00-0000 description Alcatel phone

#

vlan 9

name VoIP

#

vlan 10

name Client

#

interface GigabitEthernet1/0/10

port link-type hybrid

undo port hybrid vlan 1

port hybrid vlan 10 untagged

port hybrid pvid vlan 10

voice vlan qos trust

voice vlan 9 enable

loopback-detection enable

loopback-detection action shutdown

poe enable

stp edged-port enable

 

The DHCP scope for VLAN 9 is also configured on the HP 5120 EI switch:

 

dhcp server ip-pool dhcp_vlan9 extended
 network ip range 10.9.10.10 10.9.10.250
 network mask 255.255.255.0
 next-server 10.11.11.1
 gateway-list 10.9.10.254

Sometimes the Alcatel phones have to be rebooted MANY times, before they are ready. This behaviour is strange...

Hi Leanordo

I would try 3 things one by one

we have an installation with 5500's working with Alcatel phones. I have checked our general setup config and these seemed to be different to me.

1-under interfaces that are connected to phones disable auto voice vlan

2- system view disable voice vlan security

3- use trunk ports at the interfaces instead of hybrid ports.

Hi.

 

It seems to me that you are missing one setting in this interface:

 

port hybrid vlan 9 tagged

 

Since you don't have the permission to the voice VLAN tagged on the interface, the phone wouldn't work properly.

 

And more: in all my implementations I've been using the hybrid port link-type with success. This settings can be increased with the tips mentioned by our buddy above.

Hi mertdemi,

 

what you are proposing is a manual voice configuration. As far as I know you cannot connect a PC behind the phone in such an environment. But we use this kind of connection, therefore we need the auto-voice-vlan configuration.

Re: VoIP configuration on HP 5120 EI switches (Alcatel IP phones)

Hi Fred_Mancen_1,

 

I tried the command, but only got an error message:

 

[SWITCH-GigabitEthernet1/0/10]port hybrid vlan 9 tagged
 In auto voice VLAN mode, a Trunk or Hybrid port can not be added to or be deleted from voice VLAN manually when voice VLAN is enabled on it.

 

The phones are working with the configuration I posted. We just have strange behaviours here and there (as I stated before). I'm trying to isolate them and trying to find out if the phones or the switch config is the problem.

Hi LS1971

 

To tag the Voice vlan, you'll need to undo the voice vlan first.  That should allow you to tag it.  

 

 

If used the below port config with an ip phone and was able the use the passthrough port for a pc if you need to try another config. 

 

interface GigabitEthernet#/#/##
port link-type hybrid
undo port hybrid vlan 1
port hybrid vlan 40 tagged
port hybrid vlan 18 untagged
port hybrid pvid vlan 18
undo voice vlan mode auto
voice vlan 40 enable
poe enable
stp edged-port enable
#
return

Hi Lrod78,

Hi Lrod78

how do you configure your IP phones? Do you manually configure the VLAN-ID on them? We want to be able to attach the IP phones to the network out-of-the-box without having to configure anything on them.

The only thing they are set for is to pick up an address via DHCP.  There's nothing else really done.  

 

Are they still not grabbing an IP from the correct VLAN?

Hi Leonardo,

I have the same issue with Alcatel IP Phone. Did you solve this issue? Can you share your config?

Thanks.

Regards.

Re: VoIP configuration on HP 5120 EI switches (Alcatel IP phones)

Hi mekand,

here's what the configuration of one of our 5120-EI switch looks like.

VoIP config:

voice vlan mac-address 0080-9f00-0000 mask ffff-ff00-0000 description Alcatel phone
#
vlan 69
 name VoIP
 quit
#
vlan 71
 name Client
 quit
#
interface GigabitEthernet1/0/1
 port link-type hybrid
 undo port hybrid vlan 1
 port hybrid vlan 71 untagged
 port hybrid pvid vlan 71
 voice vlan qos trust
 voice vlan 69 enable
 undo enable snmp trap updown
 undo enable log updown
 loopback-detection enable
 loopback-detection control enable
 loopback-detection per-vlan enable
 loopback-detection action shutdown
 poe enable
 stp edged-port enable
 lldp voice-vlan 69
 quit
#

DHCP config:

dhcp server ip-pool dhcpvlan69 extended
 network ip range 10.11.12.100 10.11.12.200
 network mask 255.255.255.0
 next-server 10.18.19.1
 gateway-list 10.11.12.254
 quit
#
interface Vlan-interface69
 description VLAN69
 ip address 10.11.12.253 255.255.255.0
 dhcp server apply ip-pool dhcpvlan69
 quit
#

Asuming a 10.11.12.0/24 VoIP-subnet and the Alcatel telephone system's IP being 10.18.19.1. Hope this helps. :-)

Hi

Could you give a hand for H3C configuration !!

Hmm... HP Comware = H3C, so the config should be the same! :-)
