[c-nsp] Interface down on errors

[Rick Williams]

Hi David,

It should be possible to use the interface reliability:

FastEthernet0/0 is up, line protocol is up
   Hardware is i82543 (Livengood), address is 0009.e94f.8408 (bia  
0009.e94f.8408)
   Description: just a test
   Internet address is 88.1.21.1/24
   MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec,
      reliability 255/255, txload 1/255, rxload 1/255

reliability 255/255

as an EEM event trigger. When below some number, take action.

Regards,

Rick Williams,
