•General Guidelines and Limitations, page 5-7

•Upgrade and Downgrade Limitations, page 5-8

•Difference Between TE Ports and TF-TNP Ports, page 5-8

•Trunking Misconfiguration Examples, page 5-10

General Guidelines and Limitations

The trunking feature has the following general configuration guidelines and limitations:

•F ports support trunking in Fx mode.

•The trunk-allowed VSANs configured for TE, TF, and TNP links are used by the trunking protocol to determine the allowed active VSANs in which frames can be received or transmitted.

•If a trunking enabled E port is connected to a third-party switch, the trunking protocol ensures seamless operation as an E port.

•Trunking F ports and trunking F PortChannels are not supported on the following hardware:

–91x4 switches, if NPIV is enabled and used as the NPIV core switch.

–Generation 1 2-Gbps Fibre Channel switching modules.

•On core switches, the FC-SP authentication will be supported only for the physical FLOGI from the physical pWWN.
