Yeah, that's what it looks like. Your first router isn't getting a clock from the line. Assuming it was an in-place upgrade (so you didn't toch anything) that looks like a telco problem.

Because some MM cable has a small flaw exactly in the center of the fiber (depending on the fabrication process, I believe). The MM interface isn't bothered by it because it completely fills the entire fiber, but the SM interface doesn't; it would run slam-bang into the flaw. What the conditioning cable does is slightly offset the SM laser from the center of the MM fiber, avoiding the flaw. That's also why you don't always need it; if your MM fiber is made differently, it may not have that flaw. At least, that's how I always understood it. Regards, Marco.

The IHL is 4 bits long, and thus can have a maximum value of 2^4-1=15.
Which, in turn, means that the IP header could in theory be a maximum of
15 32-bit(=4 byte) units ('words') long, or 60 bytes.

Think MTU and fragmentation. An *IP packet* can be up to 64KB large, but
that does no mean that the underlying network must be able to transmit
or receive *frames* that long.

If you *force* 100/Full at one end and leave the other end on auto, you get a duplex mismatch. If the autoneg end sees that the other end does not autonegotiate, it will fall back to the least common denominator, half duplex. If you must force one end and not the other, use half duplex.

Is this a valid argument? The wording is a bit iffy, but he's correct in principle. Two 100M capable stations will negotiate 100 Mbps, even over CAT3 or -4, if left to autonegotiate. And that won't work. So either lock down all stations to 10, if you use unmanaged 10/100 switches, or use 10 Mbps hubs, as he said. Regards, Marco.

Yup, that's how I understood it as well. The CPU must be interrupted in all cases, because otherwise, how could it know a packet had arrived? Unless you're doing distributed switching of some kind, of course; in that case, the receive interrupt needn't be seen by the main CPU at all. > However, I wasn't able to glean an answer to the original question about the > second part of the statisitic when you do a show interface.

IIRC, it's exactly the other way around. CPU used within interrrupts is traffic being fastswitched, where the entire packet I/O is done in the interrupt handlers. Process switching lots of traffic would show up as the 'IP Input' (assuming it's IP traffic) process eating lots of CPU. (Perhaps I should re-read 'Inside Cisco IOS Software Architecture'...)

As far as I can see, the first is right. There doesn't seem to be a PRI WIC. Looks like you need a 2600 and an NM-1CE1B (UTP) or NM-1CE1U (coax). But I'm willing to be corrected :-). Regards, Marco.

That's because the NP you have (NP-2E or NP-6E?) can't do anything but 10/half, so it doesn't display it. There would be a 'hdx' or 'fdx' if it did, something like this: Encapsulation ARPA, loopback not set, keepalive not set, hdx, 100BaseTX This is from a FE interface, obviously, but it should look similar with a NP-2E-FDX.

OR Should I have the two router with the same interface > type IR or LR ?? Nope, should work in principle. You might need a few dB attenuation added to avoid overloading the receivers, though. Assuming your path is a single fiber (Two connectors, no splices) your path loss is roughly 3.5 dB. The transmitter power of the SMI interface is -15 dBm, and with the max receive power of the SML receiver being -10 dBm, you're 1.5 dB short. Same with the SML TX; that's -5 dBm (or more), and the SMI receiver may not be able to handle a -8.5 dBm receive power. You'll have to experiment a bit with that. Regards, Marco.

Yes, it does. the max 128M is 4 x 32M, and 64M is 2 x 32M by default, although I guess 4 x 16M (or two times the standard 32M as 2 x 16M it comes with normally) would probably work as well.

The 'G' feature definition (as in IGS-'G'-L) means ISDN subset, which doesn't support the serial ports. All he needs to do is put in a normal (non-'G') image, and they'll work just fine.

Look at ftp://ftp.hp.com/pub/networking/software/59692320.pdf (the docs for the 4000M), especially page 6-62 & up. Basically, they just have to assign the same port to both VLANs and make them both 'tagged'. That should work. (Note, I haven't seen a Procurve in my life.
