Dell N2048p can't separate IP voice & Data on same port

Hi all

Im new on dell switch and i need some advice about configuring voice vlan. I have 7 N2048p Switches and connecting IP Phone and PC on same port, for configuration of vlan is

Data VLAN is 101 with IP range 10.206.101.1-254 /24

Voice VLAN is 100 with IP range 10.206.100.1-254 /24

after update firmware dell switch to 6.5.3.3 most of IP Phone device using IP Data VLAN and not use IP voice VLAN. here is the capture

Hi,

Try setting the port mode to general, the PVID to the untagged vlan 101 and the tagged vlan to 100. Page 756 https://downloads.dell.com/manuals/all-products/esuprt_ser_stor_net/esuprt_networking/esuprt_net_fxd_prt_swtchs/networking-n4000-series_administrator-guide10_en-us.pdf

Hi Josh

Thanks for the reply

after change to general mode, testing in 1 port in Switch, IP Phone and PC can't get IP from DHCP Server. the changed command :

description "User_Wing_A"
spanning-tree portfast
switchport mode general
switchport general pvid 101
switchport general allowed vlan add 100 tagged

 

if i revert back configuration, PC and IP Phone get IP from DHCP but using same Subnet and VLAN

description "User_Wing_A"
spanning-tree portfast
switchport access vlan 101
switchport voice vlan 100

 

and if configuration only voice VLAN IP phone didn't get any IP, but voice vlan is enabled

description "User_Wing_A"
spanning-tree portfast
switchport voice vlan 100

HI All,

Did you solve your issue ?

I'm trying to implement 2 Dell N2048p on the same as your but I'm facing the issue with DHCP lease.

If you can shar your config or help in any other way it will be appreciate.

Thanks

Best Regards

Hi sorry for late response

until now i cant determine cause of problem, but if i turn off voice vlan on problem port, the issue in solve, but IP Phone and PC using same VLAN (in my case all using VLAN98). I tried to call dell tech support and he give me a few changes:

 

disable tlv-select port VLAN --> no lldp tlv-select port-vlan
Disable green mode             --> no green-mode eee
reset PoE Power                  --> power inline reset

some IP Phone has successfully using these command but some IP Phone can't, I tried update firmware to 6.5.4.4 but didn't resolve the case

if im looking log on Cisco IP Phone, log say "DHCP timeout", i wonder why problem just on few IP Phone but another IP Phone works normally

Also another device using voice VLAN (Polycom trio+8000) cannot get network, but if im using data VLAN, these device works normally.

No Events found!
