• HP StorageWorks 4/256 SAN Director and the HP StorageWorks DC SAN Backbone Director
platforms running Fabric OS 6.2.0.
F_Port masterless trunking interoperates between Access Gateway (AG), 2 Gb/s, 4 Gb/s, and 8
Gb/s-based platforms. This feature does not work on M-EOS or third party switches.
Figure 75 shows a switch in AG mode without F_Port masterless trunking. Figure 76 on page 445 shows a
switch in AG mode with F_Port masterless trunking.

NOTE: You do not need to manually map the host to the master port because Access Gateway will
perform a cold failover to the master port.
To implement F_Port masterless trunking, you must first configure an F_Port trunk group and statically assign
an Area_ID within the trunk group. Assigning a Trunk Area (TA) to a port or trunk group enables F_Port
masterless trunking on that port or trunk group. When a TA is assigned to a port or trunk group, the ports
immediately acquire the TA as the area of its PID. When a TA is removed from a port or trunk group, the
ports will revert to the default area as its PID.
F_Port trunking considerations
Table 87 describes the F_Port trunking considerations.
