Voice VLAN DHCP Issues

  • 1.  Voice VLAN DHCP Issues

    Posted 05-11-2018 15:51

    Our company just recently signed with VOIP provider and they shipped us a couple Polycom phones to test with and Im unable to get DHCP working on my voice VLAN on my EX3400 switches. We will be using VVX201 and VVX311 handsets.

     

    I have included the current config of my switches, am i possibly missing a DHCP Option ? I have a DATA and a VOICE vlan on my switches and DHCP is served from my SRX550. I can confirm that DHCP is issuing an IP address for my VOICE vlan because when I run the "show dhcp server binding" command, i can see MAC of the Polycom phone but the STATE still says SELECTING. My DATA vlan works just fine with no issues.

    Does your SRX have a route to 10.1.10.0/24 configured?
