Trunking Misconfiguration Examples - Cisco MDS 9000 Series Configuration Manual

Configuring Trunking
Note In case of TF or TNP ports, the Device Manager will show the port status as amber even after port is up and
there is no failure. It will be changed to green once all the VSAN has successful logins.
This example shows a TF port information after the port is in the up state:
sw7# show interface fc1/13
fc1/13 is trunking (Not all VSANs UP on the trunk)
This example shows the TF port information when a server logs in on noninternal FLOGI VSAN. VSAN
2183 is moved to the up state when the server logs in to VSAN 2183.
w7# show interface fc1/13
fc1/13 is trunking (Not all VSANs UP on the trunk)
182-2183)

Trunking Misconfiguration Examples

If you do not configure the VSANs correctly, issues with the connection may occur. For example, if you
merge the traffic in two VSANs, both VSANs will be mismatched. The trunking protocol validates the VSAN
interfaces at both ends of a link to avoid merging VSANs (see
