Green is the new black

I received a “Green Update” e-mail today and after glancing over the subjects something caught my attention:

“Announcing time–based PoE on all modular Catalyst PoE linecards – EEM script solution to turn off PoE devices based on time – First platforms to offer PoE, ePoE management through switch – Script for Catalyst 6500 at: TIME BASED POE SCRIPT – Script for Catalyst 4500: look for an announcement soon With the support of EEM and scriptable actions, it’s possible to schedule the activation of PoE for a ‘time-based’ operation. This can have a very significant impact for large IP Telephony installations where voice services are not needed during non-business hours.”

 

Here’s a script that can turn-off telephones during non business hours – if nobody is in a building why power all of the phones?

Two TCL scripts are included in the download, one to turn-off PoE enabled interfaces and a second to search for PoE interfaces in an “off” state and enable PoE again.  EEM triggers the scripts using Cron at customizable times each day (e.g. 6am and 8pm)

Impressive stuff!

 

A quick update on my studies:

As you have probably noticed I’ve not been blogging to often recently – the reason is because I have given myself a strict schedule between now and my ‘most recent’ exam date.  I have setup a series of Outlook appointments telling me what I should be studying each night – I’m adamant that I won’t put my exam date back again and that’s why I’m being ultra-strict with myself.
During my most recent look at BGP I came across the very interesting “non-exist-maps” and “exist-maps” – I have started a post about them and will aim to get it finished in the near future…
