Dell PowerConnect 6248P: Enable VLAN 1 in Trunk Mode
I just received a Dell PC 6248P and our environment is in the middle of transitioning to a vlan'd environment. However, we still have a lot of devices in VLAN 1 and this works fine with our PC 3xxx models.
However, if I attempt to make a trunk port on the 6248P, it automatically removes vlan 1 as being able to traverse the port:
interface ethernet 1/g17
switchport mode trunk
switchport trunk allowed vlan add 100
switchport trunk allowed vlan remove 1
exit
This is a new behavior with the 6248P as it works fine with our 3448P. Is there any way to correct this? I recognize that it's not ideal to have devices on the management vlan but until we complete the migration, it's necessary.
The end picture should be:
Port is set to trunk
When you look at the port it should show:
VLAN 1: U
VLAN 100: T
Instead mine currently shows:
VLAN 1:
VLAN 100: T
Thanks!

on 62xx switches, use "general mode" when you need vlan 1 to be untagged on a trunk. For example:
interface ethernet 1/g1
switchport mode general
switchport general allowed vlan add 2,3,4,5 tagged
switchport general allowed vlan add 1 untagged <<<<<<<
switchport general pvid 1 <<<<<<<<<<<<
exit

Same exact problem. Did you ever find a solution?

I have run into another problem similar to this thread that I have been unable to solve.
First, we have two buildings with a singlemode fiber run between the two. The fiber comes directly into LX transceivers on a 6248p PowerConnect switch at each building. The switch at building 1 has an up-link port to a cisco switch which serves as the core for our VoIP system. The up-link port is configured as noted above..
Ex..
Interface Ethernet 1/g45
Switchport mode general
Switchport general allowed vlan add 2
This is working perfectly and devices on the 6248p at building 1 are having no issues. The answer in this thread yesterday solved that problem.
However at building 2 and the second 6248p I cannot get any traffic to pass through on VLAN 2. I can pass traffic on VLAN 1 without issue between the buildings using basically the same config on both ends of the as I used for the up-link port at building 1. Since I could not get any connectivity on VLAN 2, I changed the the port config connected via fiber to this:
Switchport mode trunk
Switchport trunk allowed vlan add 1,2
However this did not work either. Any suggestions?
Thanks in advance.
