Re: cisco 2950 and trunk negotiation [7:63466] posted 02/21/2003
[Chronological Index] [Thread Index] [Top] [Date Prev][Date Next] [Thread Prev][Thread Next]


I read somewhere on cisco.com that the 2950s do not support ISL (it's true,
I tested it) the 2912 and 2924 series support both (2916M need a special
module for trunk), an the 1900XL series just support ISL (also tested). I'm
not sure about the 2820 series but as I think they woul have the same
trunking feature as the 1900 series.
 Somewhere on cisco.com is a doc page about the trunking features along the
different generations of low end switches

Regards,

Jose
