LLDP 5320 EXOS ToIP policy flags

[Hatem]

Hello,

I configured a stack composed by 5 units 5320, the configuration is the same for all ports, but one port detects LLDP and let IP phone to ask IP on tagged Voice VLAN, but an other port continue to ask IP on untagged (data vlan).

the first one : - Application type : Voice

                        - policy flags : known, tagged

the second :  - Application Type : Voice Signaling (2)
                         - Policy Flags : Unknown Policy, Untagged (0x0)

can you help me to know why ?
