Is 802.1x fairly straight forward?

Turn it on globally, already have AAA and Radius servers defined and working with SSH logins (we're even doing AAA login groups and the like on certain devices). I'll need to "add aaa authentication dot1x default group radius".

Turn it on on the interfaces, have it set port control to auto, etc?

Are there any changes I need to make on a Radius server or for an eventual NAC server?

Anything I need to do with VLANs?

Short answers:

I think so.

You'll want a few others.

Possibly, depending on what you want to have happen based on auth state.

See last response.

I'm not being a dick. IBNS has a ton of features you need to read up on. Is this a "hey can we do this" idea? Or is this a "Hey, we have these requirements and are looking at 802.1x to be part of that solution"?

It was more or less "Hey, were getting a NAC. Read up on 802.1x and do some testing and figure it out". So here I am.

I've gone over the config guide but its a little obtuse. Wanted to hit the thread up for any quick advice. About to setup a 3750 for testing purposes now.

We got talked into purchasing Prime to replace WCS, so please post any hints you come up with on NAC. It's not something I really want to deploy, but sounds like Cisco's trying to press the issue. I can't have a meeting with my rep without some hard-sell presales engineer FUDding me about how I'm not doing NAC.

wired 802.1x is full of so many caveats it's nearly unimaginable.

I don't know the current state of things, but when I looked most recently, following the command overhaul in IOS, it was still messy.

I was asked to implement wired 802.1x a few years ago, and I dug my heels in hard to avoid having to do it. It's such a terrific way to guarantee that periodically machines will be shunted off the network.

Yeah, that's what I thought. I'm hoping I can duplicate my current WCS functionality in Prime and ignore anything related to wired auth.

I have a login to various cisco routers and switches in our company. I need to change the password of the other person who has an account on those same switches and routers.

How do I go about doing that? Is it different for different models? Or is it all the same across ios?

same across IOS. 'privilege xx' is optional. 'secret' or 'password' can be used, 'password' will give you reversible type 7 encryption while 'secret' is MD5/more secure. If it is because some guy is getting fired, reset enable passwords too.

Well if you get fired then there won't be any more users to delete.

We use RADIUS/LDAP so we can disable accounts without modifying configs. I'd keep an admin user with some obnoxious password in the configuration to use as a backup, then individual accounts for users for various reasons.

+1 for this, centralized TACACS+ tied into a directory service, and local backup account and enable secret. If the TACACS+ server is up and available the backup account/enable secret won't work.

And while you're setting this up, set up RANCID too. You'll thank us later.

See, heres the thing. I dont know how to change a password in IOS, or lock an account out. RADIUS tied back to AD through LDAP is a bit beyond my current IOS knowledge, although I agree that we should head there.

So, is just changing the password the best bet?

Unless you think you're going to need to give that user or someone else access to the router using that username then just delete it (from another account). Change the enable secret while your at it (unless you give all your users privilege 15 or something).

If you have local in your method list you should be fine if: it is before another source (or only source), or if the connectivity to external stores is down. Presuming its configured. I think.

My work just dumped a ton of money into getting a bunch of Cisco 3502i access points. They seemed fine when they tested one.

However, after installing them (dozens), we've ran into one big problem: iPhones and iPads cannot connect (most of our mobile devices).

We get a bunch of "Unable to connect to xxx network" errors. If we try and retry and retry, eventually they connect. I'm talking 20+ attempts.

We disabled the specific SSID's use of the 5ghz and whoala no more Apple iPhone and iPads connection issues.

iPhones don't use the 5GHz frequency, so I don't know if that would be an issue.

To answer your question about controller, 3500+ series can't even be used without a controller. See here: http://www.cisco.com/en/US/prod/collateral/wireless/ps5678/ps10981/data_sheet_c78-594630.html

Stuff we've seen may be related to the iPads/iPhones seeing too many SSIDs and not gracefully connecting to the closest WAP (since they're all broadcasting the same thing). Setting found to help is under Controller>General>Fast SSID change (enable)

What kind of range? How many devices can be connected to one? The people installing them here are seriously putting them about 30 feet apart.

That sounds hella dense and your b/g/2.4GHz channels are going to interfere with one another. The controller should power down all but three of those radios (1 is full power, 8 is almost none), if you're using RRM. However, your a/n/5GHz radios should be golden and you'll be able to throw video/phone traffic/whatever you want over that. That's why you put APs on a controller.

If you want to get serious, get Ekahau heatmapper (or Fluke, etc. if you have budget) and put yourself through a survey. That's really the only way you can see what's up -- even though WCS has heatmaps, they're not terribly reliable for decision making and you need to survey it with clients on it.

The other answer to "how many devices can connect to one" has to do with the uplink: how many clients do you want to link to a single 1Gbit connection? And how many of them are 2.4GHz clients that are competing for three non-overlapping channels? One problematic client can slow the rest down. The 3502s are pretty terrific at problem isolation, finding where bluetooth or microwaves or (in my case) radar are interfering with your wireless and dynamically working around that.

Anyone here work for an MSP with a service or specialty on managing WANs? We are going to be replacing our MPLS WAN with a hodgepodge of Metro Ethernet providers. The company that does our circuit monitoring and who can give router config advice for these circuits is wanting a giant pile of money to continue doing so, $150/mo/site. Considering we have over 50 sites, we could easily hire a network guy just for this, possibly also a helpdesk guy as well with the price they are asking. Can anyone give me an estimate of what a reasonable price would be? The primary duties would be initial configuration assistance of the routers, monitoring them for downtime and interface errors, and being on standby to answer general to advanced networking questions regularly (less than 1 hour per month of this).

I'm sure that's on top of the circuits and to be honest it's really not that excessive. I work for a MSP doing what you describe and providing the support you're talking aboout.

We're probably in that ballpark as far as CPE router/firewall/etc. management. I think our managed firewall service is $99/mo. or so. Routers are in that same area if I recall correctly. You're asking for skilled labor on demand so it costs a little bit of scratch.

It's $150/mo on top of the circuit cost. We are looking at a variety of circuits as no provider really covers our entire footprint, but they are in the 10-100mbps range. We have a number of sites getting 100mbps metro ethernet for $200/mo/ea. Crazy cheap compared to an average cost of $900/mo for MPLS/VPLS.
