I didn't really study as much as I should have for this. I spent most of my time on TestOut and Boson practice exams. I was making mid 700's up to a 900+ one time on my Boson exams.
For my ICND2 I think I'll spend some more time reading and maybe making some study cards to supplement studying with the practice exams.
Just wondering where people usually get driver wheels or tires for steam locomotives? I'm wanting to try modeling a small engine in On3 or On30 ... drivers are only 36". I can print the actual wheels with one of the detail non-metallic materials on Shapeways but I'm having difficulty finding tires for them. I don't have a lathe, unfortunately, but I'm attempting to see if I can get either tires or the entire wheels printed in Stainless Steel.
We are using Imagicle with BillyBlues except it has a few limitations in our deployment.
First, it does reporting in a way that seems to work around usage billing. Unfortunately, our environment ended up going more towards a flat rate billing based on the number of devices an organization has.
Second, for call reporting it can't seem to track calls for devices set as an "Anonymous (Public/Shared Space)" device in CUCM. The data is there, it just doesn't include it unless a user is associated either in CUCM or if it left as anonymous and then a dummy user account is created and assigned that extension in Imagicle. Definitely not ideal and it creates extra management overhead.
Just curious what others are using in this space?
Still working on trying to improve our wireless on our campus. I've gone through multiple rounds with VARs and Cisco Wireless Experts and we've made quite a few adjustments for our residence halls in particular but I'm still getting complaints. I think some of this is simply due to interferers... in some areas I'm seeing 80%+ channel utilization with less than 5% tx and rx on the AP and it's neighbors and with a number of unknown interferers in the area with unknown effect and duty cycles. We won't know for sure until this summer when we can go in with a spectrum analyzer and disable our radios for a clean survey of the air space. Since most of our residence hall APs are in a hallway covering rooms on both sides (not great, I know, but this can't be changed anytime soon), they can see each other as neighbors fairly easily.
We don't support 802.11b anymore and that helped, particularly with roaming. A lot of complaints in the residence halls don't really involve a roaming situation though. Our engagements with the experts have indicated the following data rates for 2.4ghz:
Recent attempts to improve the situation have involved reducing the 2.4ghz cell size by modifying the RRM Power Threshold v2 trigger and Maximum Power Level Assignment. I believe, judging by feedback, this had a small positive affect but it wasn't enough yet. We also enabled a 5ghz only SSID but I've already gotten a complaint about that network as well.
My second attempt involved adjusting those settings again, this time to increase 2.4ghz cell size, and disable the 2.4ghz radio on every other AP (staggering between floors). We're in the process of seeing how this one plays out although RRM is still keeping the radios power level down so I started looking in to other possibilities.
I'd like to disable the 11 Mbps data rate... advice we got previously was to leave it on so clients could drop down to it if necessary but I'm wondering if this isn't part of the issue since as I've read this could be causing a larger cell size for AP neighbor detection. I did try to disable it on one RF profile but got an error saying "Failed to update 11b data rate as 802.11b network is operational"... do I need to disable this data rate in Wireless->802.11b/g/n->Network" first?
This is a BYOD environment so I have to support as much as possible, within reason (#sorrynotsorry802.11b). When I look up device info in Prime Infrastructure on some of the tickets I've gotten, connectivity/data rates/SNR/etc usually looks pretty good for the most part. Anyone have any similar experiences or thoughts on this?
edit Update to include some additional information... all of our residence halls are utilizing a main SSID broadcasting both 2.4ghz and 5ghz with Band Select enabled (the two residence halls I'm using to test are also broadcasting the second 5ghz only SSID I mentioned above). AP units consist of Cisco 2702i APs and some 702w/1801w deployed where we had to.
I'm at a stage where I'm looking at potential long-term software replacements. One of the areas I'm looking at is NAC... we had Cisco NAC and then went to SafeConnect. My issues with SafeConnect are no IPv6 and that it doesn't really integrate to the level I'd like with our Cisco wireless system and Prime Infrastructure.
ISE would be an obvious choice to improve in both of these areas, however, endpoint posture and enforcement seems pretty expensive with the Apex licensing. Currently, we require Windows and Mac endpoints on our wireless and residence network wired/wireless to install the policy key which allows us to enforce on banned software, OS versions/updates, AV status, DNS settings, etc. There is no policy key install for Linux, gaming consoles, mobile devices, etc so they pretty much get a pass other than having to sign-in every so often.
I asked one of our Cisco SEs about it and he seemed surprised we were doing that level of enforcement in a BYOD environment. I'm curious what other education environments, especially ones with on-campus housing networks, are doing in this area?
edit Please excuse the badly worded title... probably should have double checked that before submitting.
