4038Ext. Edition speed mismatch PC port vs Switch port
Posted: 30 Apr 2010 10:03
Dear ALU gurus,
we use 4028EE and 4038EE connected to Cisco 3560 POE switches. The switch ports on the switches are configured to SPEED=AUTO10/100,DUPLEX=AUTO. The phone is connecting to this network on the correct speed 100/Fullduplex. The problem is with the client PCs. They are connected to the phone's switchport with 1000/Fullduplex(but all NICs are configured to AUTO/AUTO). When I am trying to upload files from PCs connected via this "bad" setup to local servers connected at 1000/Fullduplex, they reach the transfer speeds only at 3MBytes/s, which shows me that this speed mismatch has really bad influence on the speed. The servers can easily receive at much higher speeds than this.
The phones use firmware NOE 3.91.60, the Cisco switch has the latest IOS installed.
What can I do to have all the phones provide only 100MBit speed to the client PCs, if their uplink port is also only rated at that speed?
Thanks for any ideas.
Regards,
WalkI
