Setup Telnet Access on Cisco Switches

Posted on September 12, 2011 by Humair

This quick lab assumes you already have an IP address for telnet assigned on the Cisco switch. Once that is setup and you are able to ping the IP address, you can setup telnet access on the Cisco switch with … Continue reading →

Cisco Port Security with Dynamic MAC Address Learning

Posted on May 31, 2011 by Humair

In this lab I used a Cisco Catalyst WS-C3560G-24TS switch [IOS Version 12.2(40)SE]. Using Cisco Port Security it is possible to associate a static MAC address to a physical port on a switch. This only allows one host with that … Continue reading →

Creating a Link Aggregation Group (LAG) in FTOS

Posted on May 9, 2011 by Humair

This lab demonstrates how to create a Link Aggregation Group (LAG) in FTOS on Force10 switches. A LAG in Force10’s FTOS is called a port channel and in Cisco’s IOS is called an EtherChannel. As described by IEEE 802.3ad, LAG … Continue reading →

How Perl/Python Scripts on Force10 S60 Switches Can Access the Internet

Posted on May 9, 2011 by Humair

Let’s say you have a Force10 S60 switch [FTOS 8.3.3.4] hooked-up at a datacenter that currently has a console connection connected to a management switch that provides external Internet access. The natted IP address is 10.0.8.10/24 and the external IP … Continue reading →

Setup OSPF on Force10 Switches

Posted on April 27, 2011 by Humair

For this lab, I use a Force10 E1200 chassis [FTOS 8.3.1.1] and a Force10 S60 switch [FTOS 8.3.3.4]. The objective is to setup a simple OSPF network. Loopback addresses are used to setup test networks.

Setup Inter-VLAN Communication via “Router on a Stick”

Posted on March 30, 2011 by Humair

This lab demonstrates inter-VLAN communication via the “Router on a Stick” method. To enable inter-VLAN communication, a trunk link is created between a router and switch. Trunk links can carry traffic for multiple VLANS. Trunk links can also be used … Continue reading →
