You do burn through a bit of cpu if you run 1:1 netflow sampling. Hence my intention to experiment with a faster cpu. Have since found a better solution to the cpu:netflow relationship.

I believe they used Celeron 2.4 for "control plane" and a bunch of StrongARM's linked with SPI to form a pseudo hardware forwarding plane. I guess it shows the age of the platform.

It’ll mean a slightly higher learning curve as I’ve only done basic JUNOS configuration before. My reasoning however is as follows 1) Having a single box handling the routing/policing means one less box to troubleshoot if any issues arise 2) JUNOS has a fairly logical layout, which while it takes a bit of getting used to is easier to read than ios – oh and the commit/rollback feature is also nice 3) The JUNOS web interface – while I prefer to work at the cli (I don’t trust GUIs) the web interface is good for a quick glance to check for potential problems by those who don’t have the cli skills 4) I need new routers anyway and have plans to redeploy my Cisco 2821s 5) $Price$ – easier to convince the boss to sign the cheque While not a contributing factor I am keen to improve my JUNOS skills, and in turn my overall routing knowledge Cheers again for all those who replied Kind Regards Jodi From: nznog-bounces(a)list.waikato.ac.nz mailto:nznog-bounces(a)list.waikato.ac.nz [mailto:nznog-bounces(a)list.waikato.ac.nz] On Behalf Of Jodi Sent: Friday, 9 March 2012 4:44 p.m. To: nznog(a)list.waikato.ac.nz mailto:nznog(a)list.waikato.ac.nz Subject: Re: [nznog] traffic shaping Thanks to all who sent advice and recommendations.

However they’re starting to wilt under the increased load and it’s time to look at replacing. I’ve been looking around at some of the more popular appliances that I am aware of (Packeteer, Exinda, Netequalizer), however I don’t want to buy a lemon. The other thought was to shape directly on the routers – have a couple of Cisco 2821’s at our borders. I’m familiar with the shaping process but have never attempted on Cisco kit before so don’t want to start down that path if it’s the wrong way to go (especially as I would be the only one who could manage it and I like the occasional day off). My main focus to is to shape at the border by IP for different classes based on our plans e.g. burst to 4meg, 2meg dedicated, 2.5 burst to 10, etc Secondary to that is reporting and 3rdly QoS Any and all advice welcome, on and off list Cheers Jodi -- Jodi Thomson Network& Systems Engineer Ph +64-6-8355800 Fax +64-6-8355811 Mob +64-21-903712 E-Mail jodi(a)team.waspnet.co.nz mailto:jodi(a)team.waspnet.co.nz www.waspnet.co.nz http://www.waspnet.co.nz _______________________________________________ NZNOG mailing list NZNOG(a)list.waikato.ac.nz mailto:NZNOG(a)list.waikato.ac.nz http://list.waikato.ac.nz/mailman/listinfo/nznog _______________________________________________ NZNOG mailing list NZNOG(a)list.waikato.ac.nz mailto:NZNOG(a)list.waikato.ac.nz http://list.waikato.ac.nz/mailman/listinfo/nznog _______________________________________________ NZNOG mailing list NZNOG(a)list.waikato.ac.nz mailto:NZNOG(a)list.waikato.ac.nz http://list.waikato.ac.nz/mailman/listinfo/nznog - -- Liam Farr skype: nz_liam mobile: +64-22-6107884 mobile: +64-27-5222624 -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQEcBAEBAgAGBQJPXrZ1AAoJEDIB8XDlmaeB0S0IAJMTCgaXaNHfmP8ITTejUF1v k6JD9RH7dcRofMX4voR58shCN1X8cpXQqCuV6YMtANPGTyJrKOqJKVMJCJ5spiID 4MHQ1JCUZpLw/BxfNE7VxECQy00TjP37Y6AK44DeuevdX+VQx54oh1azF0IIAMsa +fcDVoR6ysNnpm9uCRoT02ZnUcgo7owM6k5E0pxisDWxIwYGjwd13S186OprBEaq AaqvSKC5zD2s1LHmwHsWSLEsKz+ZrKbHuQdJuiFqmh6zUncrrx06NSDvUVTWnxgk qHG1MHl7V+A5v2wAbrPG0H/i0dvLFfcw5SPWBxtCAtw+vmhblr5s4yuuN+5cK+I= =3Zog -----END PGP SIGNATURE-----
