ROUBLESHOOTING
Ensure that you are using multi-mode fiber (MMF) when using a 1000BASE-SX GBIC,
and single mode fiber (SMF) when using a 1000BASE-LX GBIC. 1000BASE-SX does not
work with SMF. 1000BASE-LX works with MMF, but requires the use of a mode
conditioning patchcord (MCP).
VLAN
S
You cannot add a port to a VLAN:
If you attempt to add a port to a VLAN and get an error message similar to
localhost:7 # config vlan marketing add port 1:1,1:2
ERROR: Protocol conflict on port 1:5
you already have a VLAN using untagged traffic on a port. Only one VLAN using
untagged traffic can be configured on a single physical port.
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 whitespaces and cannot
start with a numeric value unless you use quotation marks around the name. If a name
contains whitespaces, starts with a number, or contains non-alphabetical characters, you
must use quotation marks whenever referring to the VLAN name.
