Have you ever wanted to find out what are the differences in Cisco Catalyst 6500/6800 IOS packages (or feature sets)? This is apparently the best source I’ve ever found: Cisco IOS Software Major Release 15SY on Cisco Catalyst 6500 Series Switches (cisco.com) It has a clear table of all the packages (IP Base, IP Services, […]

Configuring BGP Sessions in IPv6
My colleagues were faced with an IPv6 implementation case where the router IOS feature set prevented them from configuring the BGP sessions. I labbed something for them and thought this overall IPv6 BGP session configuration would be worth of documenting here because there are some differences when compared to the usual IPv4-only BGP configurations. I […]
Cat6500 FEX, or Smart Install?
I was surprised when I got a broschure in Cisco Live London 2013 that said Catalyst 6500 is supposed to support FEXes (Fabric Extenders) in the future. Does it make sense? A FEX is a device that looks like a data center LAN switch but it is not designated as a switch. FEX needs a […]
IOS 15.1SY Product Bulletin and New BFD Features
As a continuation to my previous post about IOS 15.1SY and 12.2SX, here is the product bulletin for IOS 15.1SY (for Sup720 and Sup2T): http://www.cisco.com/en/US/prod/collateral/iosswrel/ps8802/ps11821/ps11846/product_bulletin_c25-717747_ps11845_Products_Bulletin.html It presents the highlights in a different way to the Release Notes.

Catalyst 6500 IOS 15.1SY and 12.2SX
Feel free to bash on Catalyst 6500 based on this post as well, I know there are plenty of you who like to complain about this old work horse 😀 On the other hand, there are also plenty of us who run existing installations and designs and still see Cat6500 routing in the network very […]

Choosing Your Core Switches
When designing data center or campus LAN with Cisco products (see I made the point clear here immediately) a no-brainer solution is using Nexus 7000 switches in the core. There aren’t really many cases you can go wrong operationally with it in general-purpose data center or even campus environments. But, if you think they cost […]
Cisco Live 2012 London Afterthoughts
Returned from Cisco Live 2012 (the European edition in London, Jan 30 – Feb 3) I’d like to share some thoughts about the happening. This was my second time in this world-class Cisco event, the first time was in Networkers 2008 in Barcelona. This time we were four network specialists and architects attending from our […]
Sup2T CMP Console Access
