[c-nsp] 100FX Ports or Media Convertors?

Hi, we have quite a lot of 100Mb fibre distribution but it is spread across many locations so 24 fibre ports out from any location is just about enough. My question is now, the 3550-FX has gone and I need to replace some units the way forward with integrated ports is the 3750 with 24FX + 4 SFP

Re: [c-nsp] OSPF router gets separated from a broadcast

Used to happen to me all the time! We call it the Switch in the middle problem! (although the actual fault in our case usually involves an inground fibre and an mechanical digger) Design it out by not having sprawing L2 nets If all your long, damage prone links are in their own subnets you

Re: [c-nsp] 3550 Port Fault that only forwards small packets

Further info following response: Failures get progressively worse pinging from a switch as packet size increases, 10/10 from a PC at any size Traffic levels are low in general, path from the ping source 2950 below is Gb to core Gb to other core Gb to distrib 3550 100Mb to 2nd distrib 3550

[c-nsp] 3550 Port Fault that only forwards small packets

We use 3550-FX for fibre distribution and have had a couple of instances whe we've been investigating user complaints of a sudden onset of poor perfomance and found a port which has no errors of any kind will pass pings 500-1000 (btw the failure point is not around 1500) but no larger, also

Re: [c-nsp] Counterfeit gear (was service unsupported-linecard)

I'm no huge Cisco defender here, but I'm positive that if you were selling a product, you'd want to not have to spend the money to support that product, should it be counterfeit. That depends if you are supporting it for free or getting paid to support it. You make a profit when you charge $50

[c-nsp] Subject: Re: protecting cisco switches

I've had a 2950 access layer meltdown in the same way with a broadcast loop caused by a blocking uplink port intermitantly (twice in 3 months second time for long enough to identify) not receiving any data (inc BPDUs) even though up and looking healthy so it needless to say thought there had been

[c-nsp] ASA 55x0 vs McAfee Intrushield Appliance

As a McAfee IDS user with a 95% Cisco network, each time before I buy another Intrushield I ask myself 'How good is the current ASA IDS box?' McAfee sell themselves on the low ratio of false negative detection/blocking even during the worst attacks and full wire speed, ASIC based throughput with

[c-nsp] 3550 OSPF

Hi your sage advice would be appreciated! I have 2 x 3550s connected with a gigastack both running enhanced with OSPF both area zero, all interfaces/vlans covered. One 3550 has an uplink to our core (ospf) and has 1000ish routes. The other 3550 has normal adjacency with the other 3550 on all
