Hello, 2nd hand is no problem, I did not think about new stuff at all.
What about a NSE-100 ? Looks cheap on Ebay. Docs say "3.5 Mpps (PXF); 450 kpps (RP)". Is IPv6 forwarded in hardware or via RP on NSE ? Concerning Netflow on NSE-100/NSE-150/NPE-G1/NPE-G2 cards: What traffic amount is realistic ? Is the limitation factor bandwidth or pps ? What happens beyond the point it can handle to send the Netflow data properly ? Does that affect Netflow only (for example it sends incomplete data or switches to a sampling mode to reduce load) or will packet forwarding also be affected ? Im just looking for high pps capability for flooding scenarios only. If just accounting loses some data in such cases it is not a big issue. Anything else to take care of ? Concerning other/software based solutions: I prefer some box that can exchange the existing one without much time effort for testing/preparing/configuring. regards Rolf > On 16 December 2011 10:53, Phil Mayers <[email protected]> wrote: > >> On 12/16/2011 01:09 AM, "Rolf Hanßen" wrote: >> >>> Hi Andrew, >>> >>> just pure forwarding of a few public networks towards each other and >>> internet with default route. >>> No tunnels, no NAT, no DHCP, no VPN or something similar. >>> Concerning "relatively cheap": Im searching for "below 3000 Euro >>> absolutely". ;) >>> >> >> You'll get nothing in the Cisco range with that feature set for that >> price >> unless you go 2nd hand, IMO. >> >> Netflow at the same time as 1Gbit/sec is the killer - platforms that do >> both are lots. >> >> At this level of performance, consider whether a network tap & linux >> machine with one of the software flow capture engines would be an >> alternative - then buy a low-end 3x50 catalyst, which will easily >> perform >> and do IPv6. >> >> Or tolerate <1Gbit/sec and buy one of the ISRs. > > > > ASR1001 would be my recommendation or there is a "service module" for the > Cat 3560X switch that adds netflow capability. > > ASR1001 MSRP $17k + $5k for IP BASE licence > > WS-C3560X-24T-S MSRP $4,300 + $3,750 for C3KX-SM-10G service module + $500 > for dual PSU > > neither of these options is close to the 3k target, and neither is > readily > available used. > > Up until recently Cisco had few low-end router platforms that could shift > 1Gbps - only the 7304 NSE-150 or 7200 NPE-G2.
