Vocabulary words (and acronyms) for tonights reading....and the past couple of nights.
TCAM - Ternary Content-Addressable Memory
CAM - Contant-Addressable Memory
ACE - Access Control Entities
LOU - Logical Operation Unit
FIB - Forwarding Information Base
Collision Domain - Ethernet segment where a collision will be experienced.
Flooding - Forwarding a packet on each available interface except the one it was received.
Unknown Unicast Flooding - Forwarding a packet on each available interface except the one it was received because the destination MAC address's interface was unknown to the switch.
CSMA/CD - Carrier Sense Multiple Access/Collision Detection
So I am going through Chapter 2 of the Cisco Press book and it's all about the inner workings of the switch. How it learns MACs and how it uses hardware to switch (and route) at wire speed.
Not many commands for this chapter:
show mac address-table - Shows the current CAM table
show mac address-table count - Shows how many MAC addresses are in the CAM table and how many addresses are left over.
mac address-table static mac-address vlan vlan-id interface type number - Add a static entry to the CAM table
clear mac address-table dynamic [address mac-address | interface type number | vlan vlan-id] - Clear CAM table/entry.
The key topics covered in this chapter where:
Collision domains
Flooding/Unknown Unicast Flooding
Topology-Based Switching
CAM Table
TCAM Operation
Hopefully I can read some more tonight and post again, but I'm planning on making some homemade pizza and watching a movie with my fiancé...so maybe not.
