Mixing dot1q with ISL

How does mixing dot1q and ISL on a network affect STP and VLANS?

We use 14 different VLANS on both 3500XL switches running ISL and on 2950 switches running dot1q. Are we going to face any major issues. Would it bennifit me to change the 3500XL switches over to dot1q?

Thanks,

Josh

Re: Mixing dot1q with ISL

Hi,

Good question, it just really depends on what your preference is. I personally like dot1q, and set it up everywhere I can. But there sometimes where the dot1q is not supported mostly older stuff. I think dot1q would be better for future expansion but that is your choice.

Regards,

Corey
