366 Administering ISL Trunking
This example shows three trunking groups (1, 2, and 3); ports 1, 4, and 14 are masters:
Trunking over Extended Fabrics
In addition to the criteria listed in ” Standard trunking criteria ” on page 360, observe the following criteria
for trunking over extended fabrics:
• ISL Trunking over extended fabrics is supported on switches running Fabric OS v3.2.0 (or later) or
v4.4.0 (or 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
trunk. (For details on this parameter, see ” Administering Extended Fabrics ” on page 341.)
Trunking distances
Enhanced trunking support for switches with Bloom ASICs is summarized in Table 86 .
Enhanced trunking support for switches with Condor ASICs is summarized in Table 87 .
