ESW500 port speed issue

jscibelli

I have an ESW500 switch with Cisco 2800 routers connected to 2 of the ports. The routers are provided by and managed by

an outside vendor. The ethernet connections for each router are showing as 100mbs/half duplex. The vendor insists that the

ethernet connections are configuerd at 100/Full (see below). The ports are set at Max capability. If I try to specify 100/full on the switch port the port shuts down.

Does anyone have any idea what the problem can be?

Thanks in advance

Joe

Just an FYI I finally found a vendor contact who resolved the problem. The Cisco router was hardcoded to 100/full, the switch port set to auto negotiate.

Onc the tech changed the router to auto negotiate the connections came up at 100/full. There is some sort of compatibilty issue (even though they are both Cisco products) If I hardcoded the switch port to 100/full with the original router setting of 100/full the switch port would go down.
