Video: 10G switches
by Anshuman Kanwar 12 Feb '10

12 Feb '10

I am capacity planning for 8-10K streams of video (150-300Kbps) through a Nexus 7000 or an EX 8200 pair. The same infrastructure will be carrying quite a few audio minutes as well. Does someone have experience with either of these platforms with this scale of audio/video ? Looking for some practical advice about buffers/specific line cards/things to avoid etc. not for the usual teal/blue debate. Thanks, -ansh

Ticket/Asset Managment system
by Brandon Grant 12 Feb '10

12 Feb '10

I am currently evaluating my options for an open source trouble ticket management system that is based on assets (the trouble ticket is opened on a particular server, network element, etc.). Also, I am hoping to find a tool that can tie in with SNMP software so I can have tickets auto-generated for certain types of SNMP traps or polling failures. Any recommendations? So far, the best two that I have been able to find are: 1. OTRS.org 2. GLIP-project.org Any insight would be appreciated. Brandon

Have you looked into any cmdb systems? There are some good open source ones. Opencmdb.org I think. Sent via BlackBerry from T-Mobile

192.255.103.x
by Hector Herrera 12 Feb '10

12 Feb '10

I'm trying to diagnose an issue with 192.255.103.x As far as I can tell from IANA, the block 192/8 is allocated to ARIN. ARIN does not have a record of 192.255.103 being allocated to anybody. Here is the issue ... the customer insists that is the correct IP and for a few hours yesterday, it was actually working. Their satellite phone can reach it, but we can't see it advertised today from any networks. The ip block 192.255.0.0/16 is allocated to "VARIOUS RIRs" under a text file I found at potaroo.net I tried a few looking glass sites, but I still can't find a route to the advertising router. So ... any ideas how to go about finding out the source of the routing block? -- Hector Herrera

If they manage the broadband abuse they way they do gmail forum spammers, I don't have high hopes. David

Sorry for the top post, BB won't let me punch this at the bottom. I believe 2.0 is in beta and supports ipv6, I don't know if beta is something you want to mess around with.

Currently using IPCop but it lacks ipv6 support. I've used SmoothWall Express but not in some time and not sure how well it works with IPv6. Not looking for something huge, just something for the equivalent of a small branch office. Site to Site VPN support and NAT translation capability for a few public IP addresses to private addresses are the only requirements.
