Catalyst Switch
Technologies
THE CCNP EXAM TOPICS COVERED IN THIS
CHAPTER INCLUDE THE FOLLOWING:
Identify the Cisco Route About-face processors and explain how
they are implemented.
Understand the action of the Content Addressable Memory
(CAM) and Ternary CAM (TCAM) aural a Catalyst switch.
Describe how arrangement assay modules on Catalyst switches
can be acclimated to advance arrangement cartage management.
Be able to catechumen CatOS to built-in IOS on Catalyst switches
and administer built-in IOS images application best convenance methods.
Describe the operation of both the Content Addressable
Memory (CAM) and Ternary Content Addressable Memory
(TCAM) as implemented in altered Catalyst switches.
Cisco switches are at the beginning of avant-garde technology, and comprise
some of the best adjustable accessories on the market. But the changing
nature of applications’ demands aloft switching is reflected in the
variety in the range. Some of the earlier switches still use a bus technology on the backbone, whereas
newer switches use a “shared memory” forwarding engine. The best avant-garde switches apply a
matrix bolt at the affection of the switch.
The acumen for this is the continuing advance of multimedia applications. Voice and video
place altered demands aloft the arrangement that can be annoyed alone by a aggregate of high
availability and configurable QoS. High availability agency that the switches accept to be nonblocking.
In added words, we don’t appetite them to get in the way!
In this chapter, you will apprentice what the altered about-face architectures are, and which type
relates to which Cisco switch. I will explain how the about-face anamnesis functions, and how the
bridging tables are stored and accessed. We will attending at the altered Cisco switches currently
offered, and see how these technologies are implemented.
We end this affiliate with a altercation of the techniques that can be acclimated to administer and troubleshoot
an chip about-face network.
