Introduction of participants with the architecture and features switches Cisco Catalyst 6500 and routers Cisco 7600.

Training format

As a standard, we implement a full-time course (onsite or ILT *) in the ALEF Training Center. Upon agreement, it is possible to implement the course at the client's premises.

Due to the impossibility of preparing a remote lab and at the same time the complexity of the course, the course cannot be implemented in online / vILT form).


  • ILT - Instructor Led-Training * - instructor-led training in the classroom. ** vILT (Virtual Instructor-Led Training) - this is a form of distance learning, where the instructor conducts training from the classroom through an online platform to which students connect from their office or the comfort of their home.


Knowledge of configuring Cisco switches, at least in the range of certified training SWITCH from Cisco Systems or specialized training A2 from Alef Nula.
