Router Config Question

[phoffeld]

I am a newbie to Cisco.  I have a router that pings another at a remote location.  We only use pings on this particular router to monitor a link, so when the pings drop we know a link is going down.  It used to do a continuous ping of the distant end router, but since restarting and adding a new IOS, the router will only ping at the max number provided which is 2147483647 times.  I know the no exec-timeout is for the user login, but what is the command to allow continuous pings?  This is a major router and I can't afford to make an config error that would shut the routers down or stop the pings.

the router will only ping at the max number provided which is 2147483647 times.

The value is the total for (2^31)-1.  

Pings?  Only pings?  What's stopping you from using SNMP to poll the remote end appliance?

Use a NMS system to monitor.  This can monitor via SNMP polls or traps generated from the link, router amongst many other things. 

There are no continous pings other than 'IP SLA monitoring'.  But for that you will need possibly additional licenses to activate that feature.

Google - 'free nms monitoring'! :)

Hi,

" the router will only ping at the max number provided which is 2147483647 times.  I know the no exec-timeout is for the user login, but what is the command to allow continuous pings?"

Use IP SLA  icmp-echo  and  IP SLA logging traps to alert you when a certain condition is met.
