May I ask a question not very relational to CCIE.
I am working for a IDC, one our customer complained their application is slow. They ask to test the ftp speed between our two switch port.
BTW, our structure is connecting customers to 6509 FE port,and 100M bandwidth supplied.We put 2 PC to 2 port, assign different vlan for these 2 port,
one to be ftp client,another to be ftp server, the test result is 300-400Kbytes/s. We can see the mls entry established by the two ip address.The customer
says the speed is too slow comparing to the port speed(100M).But we think this may be resulted in the tesing PCs or some features of FTP protocol.
But I cannot explain why the speed maybe slow between two switch ports,but very fast to other sites on the internet. Can someone help me to explain that?
We are using 6509 MSFC feature,different vlans are assigned to different physical ports,and the routing protocol is OSPF.
