Careful... The "regular" Dell PowerConnect switches (35xx, 55xx, 80xx etc.) != Dell Force10. The PowerConnect line is made of "merchant silicon" (Broadcomm, SuperMicro reference, etc.) and is nowhere near the performance or reliability of the Force10 line. Of course, it doesn't cost Force10 money either... The cheapest Force10 switch I see on the Dell site we use (Dell Premier) is $4,116 for a Force10 S25N (24x10/100/1000 copper, 4xSFP.) We do use the PowerConnect line in some non-critical applications (mostly research clusters.) The are fine for the price.

For our money, the dell (nee force10) are quite good enough and about 1/2 or better the equivalent cisco discounted price. Hp are also decent.

All the "real" Cisco switches (2960 series on up) support BPDU guard etc. The "toy" Cisco switches (ex-Linksys) I'm not so sure about. I'd look at HP or Dell (ducking!) if you want something cheaper in a managed switch. I personally don't (and wouldn't) use Linksys, Netgear, DLink etc. for production networks.

I just spent about 2 hours trying to isolate at loop caused by and ex-employee(kidding). I am aware of some methods out there with HP and Cisco switches like BDPU, or loop-protect in HP. What do you think the best solution for this using those cheap switches without such features? I also looking at limiting MAC address per port on Cisco switches. Do you know what's the cheapest model that supports this feature? Thank you for your inputs. -CD _______________________________________________ Tech mailing list [email protected] https://lists.lopsa.org/cgi-bin/mailman/listinfo/tech This list provided by the League of Professional System Administrators http://lopsa.org/ _______________________________________________ Tech mailing list [email protected] https://lists.lopsa.org/cgi-bin/mailman/listinfo/tech This list provided by the League of Professional System Administrators http://lopsa.org/
