Hi Folks,


We have a internet link with site to site VPN connection. We are facing performance issues on this link for past few days. We analyzed that internet interface of our router was negotiating with service provider modem on 10Mbps/half duplex and there was some collisions on the circuit. We asked the provider to hard code the settings to 100Mbps/Full on thier modem so that our router will negotiate 100Mbps/full settings. Will it make the performance better now? We have internet link speed of 768K upload & download..


Please let me know, if more information required.

Hi Mahi,


It will give you a better performance compare to 10 Mbps configuration setup because in 10 Mbps/half duplex and peer end 100Mbps/full duplex will end in always poor performce and lots of port error and frame error in network.Better recomendation for having a good performance port and router and modem ports need to full duplex with 100 Mbps.


and Min. requirement for site to site von connection is  512Kbits/sec of internet bandwidth at each site


Hope to help
