I have a customer who has two non-Cisco 802.11g wireless bridges linking a small building to a larger buidling housing the data centre.
They complained about poor performance for the users in the small building. Looking at the switch ports supporting the bridges I noticed that they were set to auto-negotiate and had negotiated 100Mbps full duplex.
The port supporting the bridge in the main building is showing a number of output buffer failures although this is less than 0.001% of the total number of packets sent.
My suspicion is that the switch is sending more data than the wireless network can support at certain times of the day.
I could drop the speed of the switch ports to 10Mbps but am reluctant to do this as the wireless network is running at 24Mbps and I want to try to make the most of this speed.
I am going to try running the switch ports a 100 Mbps half duplex to see if that makes a difference but am wondering if anyone can suggest any other solutions I can try.
The switches supporting the link are Catalyst 3550 10/100 with the latest basic image. This stops me doing anything too clever such as packet shaping.
Any suggestions welcome.
