Re: Cat 1900 and Full Duplex
Nevermind, I've discovered the answer. There used to be a model 1900C that is half duplex only. That is the model most prevalent at our location. That model is no longer available. The 1900 series now consists of the 1912 and 1924, both of which can do full duplex on their 10 meg ports. It turns out that we have two of those, so I verified visually that the duplex options is, in fact, in the port configuration section on the 1924 model. > Cisco's website documentation says that full duplex operation is available > on all ethernet and fastethernet ports.

Cat 1900 and Full Duplex
Cisco's website documentation says that full duplex operation is available on all ethernet and fastethernet ports. However, I have several 1900s and I cannot see how to turn on full duplex operation on ethernet ports. The fastethernet ports have an option under Port Configuration, but no such setting exists for the 10baseT ports. There is also no mention when you view the port whether it is running half or full, or if it autonegotiating.

Re: Why does anybody make the CCNA
Because the CCNA is about 1000 times easier than the CCIE, which makes it a nice entry level certification.

Re: Difference Between T1 & Frame relay
Frame Relay refers to the data network that your provider uses to get data from one endpoint to another. Inside their frame relay cloud, they usually run ATM, but that's another matter entirely. T-1 is a digital line that is used to access the frame relay network. so, you have this: Router --> CSU/DSU -(T-1)-(frame cloud)... There are other options for accessing the frame cloud, but T-1 or a fractional T-1 are the most common. You could also have a T-1 point-to-point circuit and choose not to use frame relay. In this case, you could use some other layer 2 encapsulation such as HDLC or PPP. Your choice all depends on your needs and your budget. > Can some one clearly explain the difference between T1 > and Frame relay, Does T1 run over Frame relay circuits > ?

Re: Local Director load balancing
Perhaps he's referring to an Arrowpoint content-aware web switch, which is now a Cisco box. :-) (Resistance is Futile) The Arrowpoint switches can do load balancing using such criteria as he mentioned. They are quite cool and they beat the heck out of anything Cisco has. Which explains why Cisco is buying the company! Go to www.arrowpoint.com to see the future of Cisco web switches. Now let's just hope that Cisco doesn't screw up Arrowpoint's customer service department. They are truly amazing. > Deepak, > > Where are you getting the information that you have listed about the > criteria that LD's use for load balancing? > > I have worked with LD's as recently as 2 months ago and none of these > sorts of options were available.

Re: Intermittent Packet Loss
Hmmm... we have 1900s, 2924XLs, 5000s, 5500s ,etc. And we have no problems with our LAN. 10% packet loss is indicative of a problem, but I doubt it is the hardware. Check the speed/duplex settings between the switch and the router. If they are mismatched, especially if one side is full duplex and the other is half, then you will certainly have problems. > Simply do not buy cisco for LAN.
