[ietf86-tech] Switch/AP code (was: updates in IOS 15)

[Chris Elliott]

Agreed on 15 for switches (and APs). We stick with 12.

The latest 12 code is 12.2(58)SE2, released July 2011. We have used this
release since IETF 84, so many of the switches should already be running
this code.

The latest 12 code for our APs is 12.4(25d)JA2, released Sept 2012. We've
been running 12.4(25d)JA1 on all our APs except for the one we upgraded in
the NOC to JA2. I would like to go to JA2 because of some of the bugs
fixed, like CSCtr49064: Cisco IOS Software Reverse SSH Denial of Service
Vulnerability, but I don't think it's essential. If you have the time to
upgrade to JA2, great, otherwise lets stick with JA1.

Most of the firmware for our devices for these releases is in
management.sql1.ietf.org://tftpboot/software/. Some, like the 12S switch is
not and we'll have to bug wej if we need them.

Enjoy!
Chris.
