VLAN configuration can be verified by using the following command:
show vlan <name>
The solution for this error is to remove ports 1 and 2 from the VLAN currently using
untagged traffic on those ports. If this were the "default" VLAN, the command would
be
localhost:23 # config vlan default del port 1:1,1:2
which should now allow you to re-enter the previous command without error as
follows:
localhost:26 # config vlan red add port 1:1,1:2
VLAN names:
There are restrictions on VLAN names. They cannot contain white spaces and cannot
start with a numeric value unless you use quotation marks around the name. If a name
contains white spaces, starts with a numeric, or contains non-alphabetical characters,
you must use quotation marks whenever referring to the VLAN name.
802.1Q links do not work correctly:
Remember that VLAN names are only locally significant through the command-line
interface. For two switches to communicate across a 802.1Q link, the VLAN ID for the
VLAN on one switch should have a corresponding VLAN ID for the VLAN on the
other switch.
If you are connecting to a third-party device and have checked that the VLAN IDs are
the same, the Ethertype field used to identify packets as 802.1Q packets may differ
between the devices. The default value used by the switch is 8100. If the third-party
device differs from this and cannot be changed, you may change the 802.1Q Ethertype
used by the BlackDiamond with the following command:
config dot1p ethertype <ethertype>
Changing this parameter changes how the system recognizes all tagged frames received,
as well as the value it inserts in all tagged frames it transmits.
