Figure 2 Distribution of traffic over an ISL Trunking group
Trunks operate best when the cable length of each trunked link is roughly equal to the others in
the trunk. The difference between cable lengths for participating links should be no more than
30 meters.
Advanced features
Connections between HP StorageWorks SAN Switch 4/32 models support these advanced
features:
• Up to eight ports in one trunk group
• ISL Trunking over longer distances than other models
• Dynamic trunk master reassignment if a trunk master is disabled (on other platforms, all
ports on a trunk must be disabled temporarily to reassign a master)
• 4 Gb/s trunk links
NOTE: The maximum number of ports per trunk and trunks per switch depends on the HP
StorageWorks model.
