nbar protocol discovery output and rip [7:59226]
Hi All, I'm currently using nbar for protocol discovery on a network running rip. I've noticed that nbar will ony discover rip packets inbound on an interface. The interface(s) used for this do not have passive interface set for rip or an access list denying udp 520. I'm currently using this on 2 different platforms (2610XM and 3660) with 2 different IOS codes (12.2(8)T4 and 12.2(5)) respectively. I'm starting to think that this is the norm for nbar.. anyone experienced the same results? Cheers, Mark.

I'm going to answer generally with considerations about wireless in hospitals, rather than on the specific devices. First, there's a brief review of the US privacy regulations at http://www.medscape.com/viewarticle/445787_print. You may need to register (it's free) for Medscape, which I use daily as a source of primarily pure medical information. Now, we probably haven't installed one in 12-18 months, and had bad interference problems with handheld devices that operated over a large area. Handhelds to a bed monitor, or even in a ward, tended to work reasonably well, but, as has been pointed out, there are LOTS of interfering devices. I am not aware of safety studies of wireless transmission in units where conductors go through the skin. Also remember that some instrument rooms will be electromagnetically shielded. During the process of installation, be sure to have plenty of Ethernet docking stations available that are compatible with handhelds. Our experience with PDAs is they are simply too limited for any serious medical application other than electronic reference books. We've tended to use handheld or tablet PCs, depending on display size and input requirements. For support reasons, we've tried to emphasize LINUX for these handhelds, if for no other reason that if they are running Windows, doctors (especially) will put games, stock quote, etc., applications on them, to the point that we don't know the software environment of the potentially life-critical devices we are trying to support.

Re: Question for designers (WLAN) [7:59216]
Yeah, of course, the same here, this is one of the reasons why money is not a problem (well, at least not a big problem). We already have a data network and now that we're thinking about wireless we want a robust, very secure and useful solution. I have been studying MikeS response and I can conclude that it's better to spend money in good quality devices, but the only remarkable difference between Aironet 1200 & 1100 that I can found is antennas, the 1200 series has several options and 1100 only has only an omnidirectional integrated antenna. If I'm not going to use 802.11a, I can see any reason to spend more money buying 1200 or 350. What do you think?

Re: Question for designers (WLAN) [7:59216]
wireless net in a hospital, I would think concern over privacy of customer data would prevent that. In the US, hospitals are held accountable to ensure they do all they can to protect it..

Re: Question for designers (WLAN) [7:59216]
Be prepared for alot of *fun*... more so when you get near the Cathlab or any type of MRI imaging. These things generate ALOT of noise. So do your site audit when they are running. Also, some monitoring equipment can be interfered or cause interfence.. neo-monitoring comes to mind with the wireless strip recorders. Some facilites use an inhouse phone/intercom system that can interfere. Some surgery suites now have wireless links for video and/or data. Not to mention the odd rogue AP that some decided was a good idea to add more workstations when they ran out of cable. I think you see the pattern of audit EVERYTHING and do it during the day when things are running. If you plan to run some in the basement (why is it the IS dept is always in the basement?) be prepared to have lousy coverage unless you overbuy the antenna count. Structual steel in the columms wreak havoc with the signals and not to mention all the rebar in the walls. You can get around some of this with doing some simple mods to the antennas of the APs. A simple mesh reflector can help punch through a wall.. or focus the signal down the hall to skip a AP in the middle of the hall. This is just an example. You will probably end up with an assortment of antennas.. patch, dipoles and the normal AP mounted antenna. Buy good equipment. The cheapo stuff has alot of troubles with the radiated noise, not to mention the lack of support. These are my opinions.. your milage will vary ;) MikeS -- Tutorials - Whitepapers - Security - Wireless- News Find me at www-dot-packetattack-dot-com ""David j"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > Hello friends, I have to advice what kind of wireless device we are going to > buy for a hospital.

Please advise me about this > subject. As has been mentioned, 'show environment all' will show you the thresholds the router can cope with. The 2500 series doesn't have environmental monitoring though - I'm not entirely sure about the 3661. In reality though, the cooler a piece of hardware, the longer it'll last. Our machine room is kept between 19 and 20 degrees C - it seems to be the usual standard. Something to keep in mind is the direction air flows through hardware. I've seen a setup with three racks side by side. In the first was a Netcomm modem rack, the second and third being 7206s at the same height. The heat generated in the left most rack by the modems was sucked in the left hand vent of the middle 7200, heated, expelled out the right hand vent only to be sucked in the left hand vent of the second 7200 - not optimal conditions considering the room also had medicore aircon. The ambient temperature was around 25 C, with the second 7200 getting up to exhaust temp of around 55 C (and I believe the shutdown point for 7200s is 60 C).

Question for designers (WLAN) [7:59216]
Hello friends, I have to advice what kind of wireless device we are going to buy for a hospital. If money was not a big problem what Aironet would you buy? I thought about 1200 series, but it isn't approved for using 802.11a in my country (only 802.11b) so I think it hasn't got many benefits over 1100 series (these are cheaper). What do you think? someone has implemented a wireless network in a big hospital (1200 beds)? Any feedback would be helpful, thanks in advance. Regards. David.

Thx all, it is an interesting one. I remember Don Slice at Cisco saying that they were looking into this but never got much further than that.
