Link state propagation on Cisco switches

[fibernet570]

I have two Cisco 6500 switches connected via fiber, this is my small network.  One end goes to a provider, and the other end goes to a server.  My IT department wants some sort of link state propagation since the provider keeps going down, but the IT team is unaware until they contact me.

We provide a Layer2 point-to-point circuit, access ports at the ends.  We use VLAN's to transport the traffic.

Please let me know if there is anything I could do to support link state propagation.

Depending on your IOS version, you can use an IP SLA to detect ISP link failure and use EEM to send out a notification to the server group when the server is down.

Not sure if you'e familiar with the two features but here's some docs:

For IP SLA:

For EEM:

Is there another option?

You could alternatively have alerts sent out by Network Management Software, but then you're talking about added cost and administrative overhead.  There are plenty of options out there, EEM is just a quick and dirty solution that came to mind.

Hi Antonio,

Thank you for responding. When you have time, let me know of any Layer2 options.
