I read that the 1900 switch only run Dynamic Inter-Switch Link (DISL). Does that mean that I cannot trunk between a 1900 and non cisco switch, since I would need to use 802.1q.

Does the 2820 only use DISL.

That's exactly what that means. And you can only trunk on the 100 MB ports. I am pretty sure that the 2820 will also only suport ISL trunking.

I htink if you want to use 1dotq trunking, you need a min. of either a 2900 XL model (the newer versions with 8 MB memory and entreprise edition software, 2912XL for example), or a Cat 2950. The Cat 2950 will onyl do idotq trunking I believe.

Good luck,
