DUR Switch Limits

Hello team,


Working on designing an implementation of colorless ports utilizing downloadable user roles and am dealing with some older switching technology. Currently will be deploying on some 2920 switches, and am concerned about two things:


Limitations on the number of ACL entries within a downloadable user role and limitation of total number of downloadable user roles applied to clients.


I am aware of the general ACL limit on 2920s and other platforms, but was wondering about total DUR and total ACLs PER DUR.


Re: DUR Switch Limits



It's not easy to just provide a simple answer to this. It all depends on the total amount of ACE's and some other parameters in the DUR.
