ICX 7150 48P - VoIP Phones

Good morning,
I have 2 ICx 7150 switches in stack.
This is my config

Current configuration:

end

I have 3 VLANs
100 - Date
105 - VoIP
125 - MGMT

On the 1/1/25 port (Vlan 105) I attached a VoIP phone (SNOM) that correctly takes an IP
In fact, through the "sh lldp neighbors" command I see it

How can I make the other phone's port release an IP of the VLAN 100 to be able to connect a PC (The Dual-Mode command is disabled)?

Thank you

You have to Tag each port for the voice vlan and untag the ports on the data vlan. Be sure to tag first the. Untag the data port second or it will not allow the command.
Be sure any uplinks have the vlans tagged as well.
Config t
Vlan 105
Tag Ethernet 1/1/1 to 48

Vlan 100
Untag e 1/1/1 to 48

On each port do

Config t
Int e 1/1/1 to 48
trust dscp
voice vlan 105

The next step is outside the switch. Depending on your voip equipment it may differ. I have shoretel and it requires a dhcp option 156 to be setup that specifies the vlan to hop to.

Hope this helps

Paul is right on with the reply. In Paul's reply VLAN 105 is the Voice VLAN and 100 is the data VLAN.

You might also want to add an LLDP Media Endpoint Detection profile LLDP-MED:

On a Cisco switch, you would add it under the interface as a Voice VLAN which announces the VLAN. Otherwise the equivalent would be making a trunk port then adding the data vlan as a native VLAN, which is exactly what Paul is having you do on the Brocade/Ruckus 7150 with the Tagged and Untagged Terminology where Untagged = Access port and Tagged = Trunk Port. Dual-Mode is essentially a Native VLAN, but now you tag an interface in as many VLANs as you want and untag it to only one VLAN for its native VLAN, so they have depreciated the use of the dual-mode keyword.

What I want to add to the answer,

You can announce the Voice VLAN to the phones via LLDP, too:

lldp med network-policy application voice tagged vlan 105 priority 5 dscp 46 ports ethe 1/1/1 to 1/1/48

This is what I do, and works nicely

interface ethernet 1/1/1 to 1/1/48

voice-vlan 105

trust dscp

lldp tagged-packets process

lldp med network-policy application voice tagged vlan 105 priority 5 dscp 46 ports all

lldp med network-policy application voice-signaling tagged vlan 105 priority 4 dscp 42 ports all

I followed your advice and confirm that it now works perfectly.
I only changed the interface from 1/1/25 to 1/1/29 but now I will define a range of IP addresses.
I enclose my config in case it can then be useful to someone else.

Thank you
