Could be wrong settings on the NIC connected to the switch port. Check the machine NIC settings to set to Auto-Detect for duplex and speed. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Brad Ellis Sent: Monday, September 09, 2002 11:06 AM To: [EMAIL PROTECTED] Subject: Re: why my interface keep going up and down??

Re: why my interface keep going up and down?? [7:52917]
Hi Sim, Port flapping can occur due to duplex, speed mismatch or some other reason. Check the duplex, speed of the port and the settings on the machine connected to the port Fa0/18 Check if there is an STP loop i your network When did this link flapping start? Show port will show a lot of information and also check for any error on this port. 27W5d is the switch uptime which is 27 weeks and 5 days. Hope this helps.

Re: why my interface keep going up and down?? [7:52917]
Hi Chee Tong 27W5d means that the switch is up 27Weeks and 5 Days. I had a problem similar to this and what I did to resolve it was to make sure that the Switch was hard coded to a port speed instead of Auto. regards Derek - Original Message - From: Sim, CT (Chee Tong) To: Sent: Monday, September 09, 2002 10:32 AM Subject: why my interface keep going up and down??
