I’m not sure there are as many Cisco specific Ethernet problems as people like to say, but here’s a few things I’d recommend:
a) Cisco makes many products, don’t assume they are all the same just because the label says Cisco b) My experience is to always set negotiation to auto on both ends (unless the equipment is really, really old) c) Cisco gear tends to have more interface parameters you can twiddle, as well as stats and logs you can check, check those logs and stats to see if they point you to the source of the problem and a way to fix it d) Cisco switch ports take awhile to start passing traffic (link light takes several seconds to turn green), this makes a lot of people think there is a problem, I think you can modify this with the portfast command or by disabling STP, but it is not necessarily a bad thing From: Jaime Solorza Sent: Thursday, April 07, 2016 11:17 AM To: Animal Farm Subject: Re: [AFMUG] Connecting to a a Cisco Firewall Yes Cisco gear is finicky with lots of wireless gear....except theirs...go figure On Apr 7, 2016 9:15 AM, "Rory Conaway" <[email protected]> wrote: We are taking a Cisco switch out there to see what happens.

April 2016 16:15 An: [email protected] Betreff: [AFMUG] Connecting to a a Cisco Firewall Anyone have problems with staying connected to a Cisco AS Firewall with 100Mbps? We had troubles with the Mimosa B5-Lite, at first it was fine for a few days, then started dropping the connection on the Ethernet port, then it pretty much went offline completely. We put a TS-5 in there as a quick test and it ran 24 hours, same thing this morning. The B5-Lite and the TS-5 seem to be working perfectly and we don’t have a problem with the B5-Lite attached to the Netonix on the other side. We have tried forcing all devices to 100Mbsp and it works for a while. In this case, setting it back to Auto on the T@-5 brought it back online. At this point, we are telling the client the port is bad on the Cisco since this is 2 devices with the same problem. Is this common when attaching to Cisco 100Mbps devices with 1Gbps ports?
