Verify Your FREEK

File under the category of “How the hell did I not see this before?”

I was reviewing some basic Frame Relay labs today and during a FREEK* (Frame-Relay End-to-End Keepalives) and I issued a ‘show frame pvc x’ command:

r1(config-fr-dlci)#do sh frame pvc 102

PVC Statistics for interface Serial0/0 (Frame Relay DTE)
DLCI = 102, DLCI USAGE = LOCAL, PVC STATUS = ACTIVE (EEK UP), INTERFACE = Serial0/0.12

I’ve done dozens of FREEK configurations and have never noticed the ‘EEK UP|DOWN’ in the PVC output before.  I suppose that’s because I usually just issue the ‘show frame-relay end-to-end keepalive‘ instead.  That command has a ton more information:

r2#sh frame end-to-end keepalive int s0/0.12

End-to-end Keepalive Statistics for Interface Serial0/0.12 (Frame Relay DTE)

DLCI = 201, DLCI USAGE = LOCAL, VC STATUS = ACTIVE (EEK UP)

* I’m using the “politically incorrect” name because I really don’t understand why “FREEK” is offensive to anyone.

NetworkWorld: Looking For CCIE/Cisco Blogs/Websites

NetworkWorlds’s Cisco Subnet recently posted their “Top 10 Cisco Stories of 2008”.  Number one on their list:

20 useful sites for Cisco networking professionals
Our most-read Cisco Subnet post is our pick of 20 useful sites for Cisco networking professionals. We published the list in February and since then we’ve come across plenty more useful sites, so watch this space as we’re planning to update the list soon. If you own or know of a site that should be on the list, please send an e-mail to Linda Leung (lleung@nww.com).

Somehow NetworkWorld included this blog on that list.  Please don’t let the good folks at NW make that type of mistake again.  🙂  If you have a CCIE (or other Cisco-centric) blog, go ahead an email Linda with your information.
