Information About Trunking

Trunking, also known as VSAN trunking, is a feature specific to switches in the Cisco MDS 9000 Series
Multilayer Switches. Trunking enables interconnect ports to transmit and receive frames in more than one
VSAN, over the same physical link. Trunking is supported on E ports and F ports (see
Ports, on page 199

Trunking E Ports

Trunking the E ports enables interconnect ports to transmit and receive frames in more than one VSAN, over
the same physical link, using enhanced ISL (EISL) frame format.

Note Trunking is not supported by internal ports on both the Cisco Fabric Switch for HP c_Class BladeSystem and
