About Trunking
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.
Figure 24-1 Trunking E Ports
Note Trunking is not supported by internal ports on both the Cisco Fabric Switch for HP c_Class BladeSystem
and the Cisco Fabric Switch for IBM BladeCenter.
Trunking F Ports
Trunking F ports allows interconnected ports to transmit and receive tagged frames in more than one
VSAN, over the same physical link. Figure 24-2 represents the possible trunking scenarios in a SAN
with MDS core switches, NPV switches, third-party core switches, and HBAs.
