over the same physical link, using enhanced ISL (EISL) frame format.

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