Cogent input - no peering with Global Crossing in Europe [Re: NANOG Digest, Vol 17, Issue 46]
by AKK 18 Jun '09

18 Jun '09

My main concern for European Cogent users is - no European peering with global crossing - traffic goes via NY JFK. It has been like this for at least a year and staff been giving assurances this should be sorted soon. Probably there are more bad peerings - please share. 6: so-7-0-0c0.rt1.mil.it.geant2.net (62.40.112.174) asymm 5 14.446ms 7: so-7-1-0.rt1.fra.de.geant2.net (62.40.112.61) asymm 6 27.120ms 8: TenGigabitEthernet7-3.ar1.FRA4.gblx.net (207.138.144.45) 246.852ms 9: po3-20G.ar7.NYC1.gblx.net (67.16.134.74) asymm 12 122.810ms 10: te2-1.ccr01.jfk07.atlas.cogentco.com (154.54.11.61) asymm 12 123.003ms 11: te4-1.ccr01.jfk02.atlas.cogentco.com (154.54.1.221) asymm 13 118.334ms 12: te4-3.ccr01.lon01.atlas.cogentco.com (130.117.1.106) asymm 14 198.997ms 13: te2-7.ccr02.ams03.atlas.cogentco.com (130.117.1.169) asymm 14 204.575ms 14: te2-3.ccr01.dus01.atlas.cogentco.com (130.117.3.90) asymm 15 213.653ms 15: te7-1.ccr01.muc01.atlas.cogentco.com (130.117.49.154) asymm 14 225.144ms 16: te3-1.ccr01.vie01.atlas.cogentco.com (130.117.49.30) asymm 22 254.543ms 17: te3-8.ccr01.bts01.atlas.cogentco.com (130.117.49.25) asymm 21 248.505ms 18: te1-1.ccr01.tsr01.atlas.cogentco.com (130.117.48.58) asymm 20 243.334ms 19: te1-3.ccr01.tsr01.atlas.cogentco.com (130.117.0.18) asymm 20 249.374ms 20: 149.6.112.2 (149.6.112.2) asymm 19 273.730ms 21: 149.6.112.2 (149.6.112.2) asymm 19 268.122ms 22: down-int.caucasus.net (62.168.172.205) asymm 21 268.647ms 23: down-int.caucasus.net (62.168.172.205) asymm 21 274.430ms 24: sw.caucasus.net (62.168.168.60) asymm 21 277.811ms nanog-request(a)nanog.org wrote: > Send NANOG mailing list submissions to > nanog(a)nanog.org >

Unicast Flooding
by Brian Shope 18 Jun '09

18 Jun '09

Recently while running a packet capture I came across some unicast flooding that was happening on my network. One of our core switches didn't have the mac-address for a server, and was flooding all packets destined to that server. It wasn't learning the mac-address because the server was responding to packets out on a different network card on a different switch. The flooding I was seeing wasn't enough to cause any network issues, it was only a few megs, but it was something that I wanted to fix. I've ran into this issue before, and solved it by statically entering the mac-address into the cam tables. I want to avoid this problem in the future, and I'm looking at two different things. The first is preventing it in the first place. Along those lines, I've seen some recommendations on-line about changing the arp and cam timeouts to be the same. However, there seems to be a disagreement on which is better, making the arp timeouts match the cam table timeouts, or vice versa. Also, when talking about this, everyone seems to be only considering routers, but what about the timers on a firewall? I'm worried that I might cause other issues by changing these timers. The second thing I'm considering is monitoring. I'd like to setup something to monitor for any excessive unicast flooding in the future. I understand that a little unicast flooding is normal, as the switch has to do a little bit of flooding to find out where people are. While looking for a way to monitor this, I came across the 'mac-address-table unicast-flood' command on Cisco switches. This looked perfect for what I needed, but apparently it is currently not an option on 6500 switches with Sup720s. Since there doesn't appear to be an option on Cisco that monitors specificaly for unicast floods, I thought that maybe I could setup a server with a network card in promiscuous mode and then keep stats of all packets received that aren't destined for the server and that also aren't legitimate broadcasts or multicasts. The only problem with that is that I don't want to have to completely custom build my own solution. I was hoping that someone may have already created something like this, or that maybe there is a good reporting tool for wireshark or something that could generate the report that I want. Anyone have any suggestions on either prevention/monitoring? Thanks!! -Brian

Methinks "consider the source", when evaluating the 'meaningfulness' of the comlaints, goes a long way towards clarifying the situation. In -that- light, I'm really not all that 'surprised' at what shook loose from the belfry.

Couple of comments: Regarding ISM spectrum sharing: the 2.4 GHZ band (2400-2500 MHz) and the 5.8 GHz (5725-5875 MHz) are certainly shared with ISM devices- microwave ovens, induction heaters, etc. However, the 5.2 and 5.4 GHz unlicensed bands (UNII) are not shared with ISM devices. However, these bands are subject to FCC regulations that mandate radar sensing and avoidance. This means that if your radios detect the signature of a military radar system on their active channel, they will automatically shut down and begin a waiting period before switching to another channel. Mandatory 60 second outage. There are generally three classes of point-to-point high speed unlicensed data radio gear out there today: 1. Wi-fi based gear with some additional hardware and a user interface suitable for point-to-point use. Ubiquiti, Tranzeo, HGA, etc. Pretty self-explanatory. Sub-1000 range. 2. Gear using a wi-fi chipeset (Atheros, Broadcom, etc.) with a proprietary firmware load. Trango, Alvarion, Ligowave, etc. $2000-5000 range. 3. Gear using a custom designed RF interface. Motorola, Dragonwave, etc. Given your requirements, I'd encourage you to look at classes 2 and 3. Getting any decent amount of reliability from vanilla 802.11 equipment is (as you've found) difficult. Gear in categories 2 and 3 from above will generally have a built in spectrum analyzer of some sort that will be able to see interference not caused by 802.11 devices, performance monitoring systems (BER reporting, event logs, etc), SNMP capability, etc. Definitely choose a system with an integrated antenna. You want a directional antenna such as a patch array (panel) integrated with the radio. Messing around with RF cabling, connectors, etc. is not necessary with what you're trying to do. Minimize the potential points of failure. Lightning protection is a concern. Most of this gear is PoE powered, so you'll have a single cat-5 going to the roof. Make sure it's protected with an Ethernet surge suppressor that is properly grounded. Follow the radio manufacturer's recommendations here. Your antenna mount must also be grounded according to NEC requirements. The Motorola PTP400 series radio that was recommended is one of the best unlicensed point to point radios out there. However, it's been EOL'd and replaced by the PTP500. Seems like these are both out of your budget, though. As an alternative, you might consider looking at the Trango TLink45. This radio uses a proprietary firmware and an Atheros WiFi chipset. It has a rudimentary spectrum analyzer, SNMP, ARQ (important), and adaptive rate modulation. It also has a dual-polarity software switchable antenna. This greatly increases your ability to avoid interference. It will run in the 5.3, 5.4, or 5.8 GHz unlicensed bands. They retail at about $4000 for a pair, but Trango routinely runs specials. They were on special for $1700 per pair in April. The WISPA list is a great resource for help with projects like this.

WISP NMS recommendations
by Freddie Sessler 18 Jun '09

18 Jun '09

Hi Folks,I am looking for recommendations on an NMS system for use in managing a multivendor wireless infrastructure. Specifically we run mostly Motorola point to point, point to multipoint(Canopy platform) and mesh radios devices We have looked at the One Point Wireless Manager but this product in our evaluation doesn't seem to be ready for prime time and also has the limitation of only being able to manage Motorola. Ideally we would have something that could be used for configuration management in a multi vendor environment as well as recieve SNMP traps about RF issues such as latency and jitter. I am curious to what other shops are using out there. If this is a top better suited to another list, my apologies and any pointers to a different list would be greatly appreciated. Thanks JT

The current setup for this company has been extremely unstable and slow. I don't have a lot of experience in this area so I was hoping someone could give me a few pointers. Currently, both locations are using Linksys WRT54GL's flashed with DD-WRT firmware (Yes, 802.11g. All extra bells and whistles are disabled in the firmware. They were set up for WDS so other wireless clients could connect to the same access point, with varying degrees of success. Not very important). They are connected to SmartAnt 2300-2500 MHz 14 dBi directional antenna mounted on the roof (extended pretty high for perfect line of sight). I'm not sure when they got these antenna exactly but I'm told it was when WiFi was very new. The network is very small so both locations share the same subnet (192.168.1.0/24). They have gone through numerous Linksys access points over the years. The wireless settings are tweaked as best as possible, and we have found the connection to be most stable when the TX is limited to 6-9 Mbps. We have explored other options as well. An internet connection at each location + VPN is out due to very slow upstream speeds (the buildings are in an industrial area, ADSL is the only option.) The max they offer on regular business accounts is 800 kbps up. T1 lines are even slower and even more expensive. They won't offer us any other solutions such as fibre. We have considered running fibre/coax but there is too much construction activity and other property in the way. I'm looking into RouterBOARD right now, considering a RB433AH and R52H wireless card, but I'm not sure this will actually solve the problem. It's difficult to determine if the issue is with the antennas or access points (for example, after a good thunderstorm, the wireless link will be down for at least 12 hours, but will fix itself eventually. Resetting either access point will keep the link down for at least 30 minutes. Using an airgun on the access points tends to make them more reliable, even if they are clean and dust free. From the admin interface, each access point will report seeing a very good and strong signal from the other, yet they refuse to communicate until they feel like it a few hours later.) Any suggestions welcome. I'm sure you can tell cost is a bit of a factor here but it will be easy for me to justify a higher price if I'm confident it will be effective. While I'm at it, I've been reading along on the list for over a year now; thanks everyone for sharing your real world experiences :) Peter ------------------------------ Message: 2 Date: Thu, 18 Jun 2009 09:18:24 -0400 From: Jared Mauch <jared(a)puck.nether.net> Subject: Re: Wireless bridge To: Peter Boone <NANOG(a)Aquillar.com> Cc: nanog(a)nanog.org Message-ID: <20090618131824.GA25957(a)puck.nether.net> Content-Type: text/plain; charset=us-ascii On Thu, Jun 18, 2009 at 09:05:56AM -0400, Peter Boone wrote: > Hi NANOG, > > I'm looking for some equipment recommendations for a wireless bridge between > two locations approximately 500-800 meters apart.

I've had good luck with Cisco Aironet gear running in repeater mode. I've done the cheap linksys thing as well and it just did not work as well as using some equipment that was better designed. I have actually found the non-IOS software on the aironet 350/340 to be more usable than the IOS software. You need to have your network be consistent. You also have the obvious interference challenges with any unlicensed deployment. - Jared some of the equipment i've used: http://cgi.ebay.com/5-Cisco-Aironet-350-WAPs-AP352E2R-A-K9_W0QQitemZ2003516… http://cgi.ebay.com/Cisco-AIR-AP1121G-A-K9-Aironet-1100-1121-Access-Point_W… -- Jared Mauch | pgp key available via finger from jared(a)puck.nether.net clue++; | http://puck.nether.net/~jared/ My statements are only mine. ------------------------------ Message: 3 Date: Thu, 18 Jun 2009 09:21:56 -0400 From: Patrick Shoemaker <shoemakerp(a)vectordatasystems.com> Subject: Re: WISP NMS recommendations To: nanog(a)nanog.org Message-ID: <4A3A3F74.6060601(a)vectordatasystems.com> Content-Type: text/plain; charset=ISO-8859-1; format=flowed Although this would probably be better suited for one of the WISPA lists, I'll respond here anyhow since there seems to be some interest. For managing Canopy elements, Motorola Prizm is probably the way to go. First of all, you'll need it to handle element authentication for your PtMP system. It will also do configuration management, alerting, and all the usual NMS stuff. It's also *possible* to get it to work with other SNMP capable devices if you want to manage other vendors' equipment. It will work out of the box with the Canopy PtMP line, PtP devices, powerline carrier devices, and (I think) the MotoMESH line. It gives you all the info you need at a glance for each element: configuration history, RF power level plots, bandwidth utilization plots, alert history, etc. FYI if you haven't used it, Prizm is a pretty clunky and slow Java-based package. The features are nice, but configuring it can be a chore.
