Hi Cliff, Fastethernet wont cure the problem, you can still run that half duplex. What causes the collisions is running in half duplex mode. Try upping it to full duplex. What full duplex does is it disables the internal loopback device i.e. collision checking ussually if you are plugged into a switch you want it to run in full duplex mode. Half duplex would be bad when you forced the switch port to full duplex. They might have done that. It would also lead to those kind of errors.
Try this and tell me if it helped :) Regards Gerhard -----Original Message----- From: Cliff Cliff [mailto:[EMAIL PROTECTED]] Sent: 02 December 2002 11:24 To: [EMAIL PROTECTED] Subject: Collision [7:58389] Dear all, Pls kindly help the following: Really I am not understand although it is simple. We colocate the router (2511) to our provider data center. Which having two ethernet interface. One connecting to date center internet and one is connecting to our own LAN (which is private ip address). So we do NAT in this router. BUt sometime, we find that the ping time to internet is abnormal and very slow. After enable the logging in our router. We find the following log: 3d01h: %QUICC-ETHER5-COLL:Unit0, excessive collisions, Retry limit 15 exceeded. We are sure that the cable is normal and our router also normal.... Our Data center connected to our router using cisco 2950 switch and having the following setting in their switch port: interface FastEthernet0/14 load-interval 30 duplex half speed 10 Anyway, it seems normal to me but the date center suggest us to using fastethernet in our router to connecting to their switch and will not having any collision. So I wonder why it is true or not? Also, why ethernet can't connect to Cisco 2950 switch and having collision?
