HP StorageWorks Fabric OS 5.3.x administrator guide (5697-0244, November 2009)

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.
