I received an alert stating that a crypto engine was 'dead'. I did a bit of digging and was able to find some output to validate this:
#sh crypto eng config

I'm unfamiliar with what this output is saying. Is the VPN Module like a line card that is plugged into the router and can be replaced? Does the HW State: DEAD mean the card is bad and needs to be replaced? What are some other show commands I can use to validate what this output is implying?
