Кстати, слабо FAQ по 2950 посмотреть?
Там написали куда бежать за ISLями:

Q. Does the Cisco Catalyst 2950 Series support Inter-Switch Link (ISL)
trunking? Are there any plans to support ISL in the future?
A. No. The Catalyst 2950 Series does not support ISL trunking, and there
are no plans to support ISL trunking on the Catalyst 2950 platform. For
those customers with a requirement to deploy ISL trunking, Catalyst 3550
switches support both ISL and 802.1Q trunks. A recommended migration to
the ISL trunking standard while still implementing the Catalyst 2950 is
to place an ISL/dot1Q-capable device between the ISL-supported device and
the Catalyst 2950 Switch.
