We have the following scenario: A router cisco 7206VXR (NPE300) connected with a cisco WS-C2950SX-24.
The router is showing a mismatch configuration between its interface fastethernet 0/0 (on I/O card C7200-IO-FE-MII/RJ45) and the switch interface FastEthernet0/1.
The interface on the switch is configuring speed/duplex auto
And the router interfaces as following
description To LAN
ip address 10.200.10.1 255.255.255.0
ip nat inside
no clns route-cache
We tryed to fix the issue, changing the router config to auto, but this card only support full/half duplex configuration.
Then the option was change the switch to full duplex hardcoding but when we did it the interface went down and only when we changed to auto the interface came up.
Thanks in advance
