I have a dell TZ600 sonicwall and 4 Dell x1052P switches in different NOC rooms. 2 in NOC-A, 1 in NOC-B and another in NOC-C. The two in NOC-A are connected by 10GBe connection and the others are 2 X Cat6e in a LAG.
4 VLANS (1, 10, 20 ,30) - On the sonicwall I create a separate network & port for each VLAN. They connect to switch NOC-A1 and the switchport is marked as Untagged for its respective VLAN. The LAG's and 10Gbe are assigned as Trunk with all 4 VLANs - I removed all others.
The Sonciwall TZ600 is DHCP for 10, 20 and 30 VLANS. VLAN 1 DHCP is handled by a windows server.
VLAN 20 is for phones I configured all switches ports 1-24 with MED and Voice-VLAN per the dell article floating around. Works great. Phones always get on the correct VLAN.
The problem I have is the no matter the switch or port I connect to either wired or wireless I may get connected to VLAN 30. Even connecting on the PC port on the phones the same thing happens. If I issue a ipconfig /release and /renew commands in command prompt I will get on VLAN 1; this may take a couple attempts.
Once on the correct VLAN (1) I'll remain on it until the next day when I re-dock and try to connect. I'll get put on the incorrect VLAN 30. I can also easily get back to VLAN 30 by reissuing the ipconfig /release & /renew commands after getting to VLAN 1.
ALL of the switch ports I connect too are set to Access with "1" assigned so I should not be able to see VLAN 30.
As a test I changed the Trunks to General and I get the same results. I checked the routing and there is just the network for the VLAN 1 which was done when the switch is assign an IP.
Why are the x1052P switches putting me in a different VLAN?
