I know this is very general, but I have a router that is getting as much as 15% packet loss with large packets (up to 1500 bytes). The MTU on both router interfaces is 1500. The router fastethernet interface is directly connected to a 2500 ethernet interface. Going into the local network no loss. Going to the 2500 losses up to 15% with large packets. No loss on smaller packets. I have an idea what the problem is, but was wondering what others thought.
Yes, there are CRC errors. the 2500 is at 10 mb and the 2621 is at 10 mb - both half duplex. However, the BW on the 2621 shows 100000. I assume that means the maximum possible and not what it is actually communicating at. Below is the relevant entry:
MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec,
reliablility 255/255, txload 1/255, rxload 1/255
Encapsulation ARPA, loopback not set
Keepalive set (10 sec)
Half-duplex, 10Mb/s, 100BaseTX/FX
What do you think? The other 2621 interface is definitely at 100 mb and full duplex. My thoughts were that I should hard code both to 10 mb half duplex.
