I tend to use dot1q, because it's the standard. Also, dot1q is
supported by all new switches while ISL is only supported by
some.
> Why would one chose to use isl instead of dot1q?
If you need to transport token-ring in a trunk, ISL is the only
way to go. Some older boxes (also from other manufacturers) don't
support dot1q.
> And can the cisco WS2948G (only G) use isl?
No. All the Granite-based switches support only dot1q.
