We have 4510's with dual 10 gig links back to 6509's. When one of our interfaces starts to accumulate crc errors it impacts the latency and availability of our end users behind the 4510. Either the interface err-disables or we manually shut it down and the other 10 gig link is unblocked by spanning-tree and traffic begins to flow as usual. Is there a way to use EEM to detect these input or crc errors and shut down the interface?
I'm looking at the below as a resolution:
event manager applet Te5/1 trap authorization bypass
"event interface name TenGigabitEthernet5/1 parameter input_errors_crc entry-op le entry-val 0 entry-type value exit-comb or exit-op gt exit-val 0 exit-type value exit-time 5000 exit-event true poll-interval 100 maxrun 10000"
action 1 cli command "configure terminal"
action 2 cli command "interface te5/1"
action 3 cli command "shutdown"
