Trunking over Extended Fabrics

In addition to the criteria listed in
for trunking over Extended Fabrics:
• ISL Trunking over Extended Fabrics is supported on switches running Fabric OS 4.4.0 and later.
• Extended Fabrics and ISL Trunking licenses are required on all participating switches.
• The vc_translation_link_init parameter must be set the same on all ports in an extended fabric. When
you enter the portCfgLongDistance --vc_translation_link_init command, specify 1 to
activate long-distance link initialization sequence; specify 0 to deactivate this mode. If you run the
command without specifying a value, 1 is assigned automatically for the long-distance link in VC_RDY
flow control; otherwise, 0 is assigned. For a long-distance link not configured for ISL R_RDY mode, this
parameter must be set to 1; otherwise, it must be reset to 0.

F_Port masterless trunking

On edge switches, the masterless trunking feature is called F_Port masterless trunking because it trunks
F_Ports; on the switches running in Access Gateway mode, this feature is called Access Gateway N_Port
trunking because it trunks the N_Ports.
F_Port trunking, provides a Trunk group between a switch (N_Port) in Access Gateway (AG) mode and
Condor-based platforms. This feature keeps F_Port(s) from becoming disabled in the case where they are
mapped to an N_Port on a switch in Access Gateway mode. With F_Port trunking, any link within a trunk
can go off line or become disabled, but the trunk remains fully functional and there are no re-configuration
requirements.
