Urgent Pls Help - Debug Ethernet Interface on ASA

Hi, is there command to debug an Interface on an ASA5510 (7.2) ?

We are experiencing intermittent disconnections on the outside ASA interface which is connected to our ISP's 1841 router.

This is bringing down our remote VPN L2L connections

I have switched the interface to 100mb Full Duplex from auto to match the setting on the 1841 and I'm using a crossover but the issue still occurs with this error in the logs

"Line protocol on Interface Ethernet0/0, changed state to down"

The Interface and VPN then comes back up straight away but all RDP sessions running over our links are disconnected

Thanks,

Chris

Re: Urgent Pls Help - Debug Ethernet Interface on ASA

Start with a " show interface " command and look for error codes.

Here is also a good guide for troubleshooting this kind of issues.

Check that you have the same interface duplex and speed settings on both ends (100MB Full Duplex).
