Description
This article describes how to manage FortiSwitch LLDP voice VLAN auto-tagging.
Scope
FortiGate v7.
Solution
- Make sure to have the voice VLAN already created by executing the following command:
# config system interface
edit "VOICE-VLAN"
set vdom "root"
set ip 192.168.88.1 255.255.255.0
set interface "fortilink"
set vlanid 88
next
end
It will be necessary to create an LLDP profile by default all ports use:
"default-auto-isl" LLDP profile
# config switch-controller lldp-profile
edit “Phones”
config med-network-policy
edit “voice”
set status enable
set vlan-intf “VOICE-VLAN”
next
end
It will be necessary to assign this LLDP profile to the port on the switch where the phone will connect. In this example, 'DATA-VLAN' is the native.
VLAN and VOICE-VLAN are the IP phones' VLANs. LLDP is enabled.
By default, for sending and receiving, make sure to have LLDP enabled on the IP phone.
# config switch-controller managed-switch
edit <SWITCH SERIAL NUMBER>
config ports
edit "port#"
set vlan "DATA-VLAN"
set allowed-vlans "VOICE-VLAN"
set lldp-profile " Phones "
set lldp-status tx-rx
next
end
This is LLDP advertising the VLAN ID.
