comment Cisco 2921 ISR Installation concerns
@HaydnWVN, a non-PoE AC system burns 60W with no modules plugged into it (reference). When you account for modules, it will consume up to 320W.

comment Cisco 2921 ISR Installation concerns
@HaydnWVN, a good rule of thumb for cooling... look at the power consumption of the unit in Watts, convert to BTUs, and that's how much extra cooling you need. Apologies, I thought you were saying you wanted to wall-mount this router

comment Retrieve Information from Cisco router in Parsable Manner
Using ciscoconfparse in java should be possible if you use jython. Please file an issue on github if you run into a jython integration problem

comment What does 'Si' mean with respect to network switches?
No, the Catalyst 2950 did not exist in the 1990s, and that is when the Si icon in question was first marketed. Perhaps you got the idea that it's "Standard Image" from Leo Laohoo's answer; while Leo is usually spot-on, in this case he's quite full of poo. The answer from acampbell on the same page is correct (and provides proof).

comment CISCO WS-C4948-10GE SFP+?
When you say "Is there an X2 module that supports this?" What precisely is the problem you're solving? You want a 3rd party X2 10GE optic? If so, single mode or multimode? How long is the fiber shot and is the fiber 50 micron OM3?

comment Switch to switch encryption over a wireless bridge (TrustSec?)
@metatheorem, 802.3 ethernet and 802.11 wifi are quite different protocols; among the most basic differences are MTU and 802.11's requirement for frame ACKs. Wifi APs and Bridges which provide connectivity between a physical wire and RF are by-definition much more than a repeater.

Please add more details to the question. Specifically, a map of the wireless subnets, how they are connected, what equipment connects them, and hopefully configs for the equipment
