Question
How do I configure a switch so Cisco Phones will "pass voice traffic"?
Environment
  • Securestack
  • S-Series
  • N-Series
  • K-Series
  • Cisco Phones
Answer
In the example below, we have the following
  • Data vlan is 20
  • Voice vlan is 30
  • Cisco Phones are connected to ports ge.1.1-23

First create the required vlans and assign ports to respective vlans
set vlan create 20
set vlan create 30
set vlan name 20 Data
set vlan name 30 Voice
set vlan egress 20 ge.1.1-23 modify-egress
set vlan egress 30 ge.1.1-23 tagged
Secondly configure lldp on the required ports
set lldp port network-policy voice state enable tag tagged vid 30 ge.1.1-23
set lldp port tx-tlv all ge.1.1-23
Thirdly, configure CiscoDP for all user ports that will have phones connected:
set ciscodp time 10
set ciscodp status enable
set ciscodp port vvid 30 status enable ge.1.1-23
