IP & IOS Features done

So last night I finally finished IP Services and NAT. IP Services contain a few different tasks like HSRP, GLBP, VRRP, DHCP, NTP etc. These are things that most of us Network Engineers should know from our work experience but it doesn’t hurt to lab the scenarios out and read the documentation! There were a few features that I never used so reading def helped me out. I don’t have enough time to put up my notes but I will do that later on. Now I have until saturday to finish rest of the stuff aka Multicast, QoS, Security etc before I head out to Pasadena for Narbik’s Bootcamp. Now it’s time to hit some GRE labs.

Finishing up Network Address Translation - NAT

I just finished NAT scenarios from Narbik’s workbook volume 4. NAT wasn’t that bad but I still took my time while going through each lab.

I am sure you already know what NAT is but here is a brief overview in CIsco’s own words

Smartports Macros - Overview & Configuration

Understanding Smartports Macros

Smartports macros provide a convenient way to save and share common configurations. You can use Smartports macros to enable features and settings based on the location of a switch in the network and for mass configuration deployments across the network.

Each Smartports macro is a set of CLI commands that you define. Smartports macros do not contain new CLI commands; they are simply a group of existing CLI commands.

When you apply a Smartports macro on an interface, the CLI commands within the macro are configured on the interface. When the macro is applied to an interface, the existing interface configurations are not lost. The new commands are added to the interface and are saved in the running configuration file.

Understanding and Configuring SNMP on Cisco 3550

SNMP is an application-layer protocol that provides a message format for communication between managers and agents. The SNMP system consists of an SNMP manager, an SNMP agent, and a MIB. The SNMP manager can be part of a network management system (NMS) such as CiscoWorks. The agent and MIB reside on the switch. To configure SNMP on the switch, you define the relationship between the manager and the agent.
