Catalyst 2960 Experiences

May 5th, 2010

I was fortunate to get a pair of new 2960‘s to play with at my day job, complete with SFP ports – model WS-C2960-24TC-L. The 2960 is the reference switch for the CCNA/ICND2 studies, so a good chance for me to get familiar with the IOS commands and configuration. » Read more: Catalyst 2960 Experiences

PPP Multilink

April 18th, 2010

I wanted to find out a bit more about how to configure and test ppp multilink (ppp over parallel links). It gets a mention in ICND2 but nothing specific on configuration. I’ve encountered it before for ISDN dial-ups from Congo and Zyxel routers so naturally I’m curious to see how it’s done the Cisco way. Multilink ppp balances the traffic equally over the links at layer 2 whilst allowing the layer 3 in each router to treat the parallel links as a single link. » Read more: PPP Multilink

Cisco OSPF to Windows Server

April 12th, 2010

As part of my CCNA studies I’ve been experimenting with routing protocols. One test I carried out was to see how easy it would be to get OSPF exchanging routes with Windows Server 2003.

PoE Non-Standards

April 12th, 2010

I’ve been looking into Power Over Ethernet to feed power to Cisco Wireless Access Points and (other vendor) VOIP phones. I’ve found a few interoperability issues.

Cisco Config needs Internet Explorer

April 12th, 2010

I found that when trying to configure a Cisco 1130AG Wireless Access Point I was getting strange effects using Firefox. For example, the second part of the quick start page was missing. Same for Safari on my Apple Mac.

CCNA

December 25th, 2009

CCNA Lab I’ve been slowly progressing through CCNA for a while now, proof that you can teach an old dog new tricks. ICND1 was mainly basic theory and an introduction to Cisco IOS command line – I surprised myself by passing 604-822 at the first attempt.

Here is my lab – a selection of switches and routers. These should allow me to do all the simulations I need for ICND part 2 and maybe beyond…

I’ve learned and implemented some new (to me) concepts from this, although practical applications have not been with Cisco equipment, I’d prefer to call them vendor neutral so far. The most interesting project was converting  a FreeBSD ntp server that used multiple network cards.  I updated this to use 802.1Q tagged vlans using an Allied Telesyn switch.

I’ve even discovered that you can do RIP and OSPF routing in Windows :0
