Service on ADC shows DOWN with monitor error: “No MIP/SNIP available”

To resolve this issue, complete the following steps:

  1. Make sure that SNIP for the subnet you are trying to connect to is added on the ADC.
  2. Verify if there exits a route in that Subnet. If the route does not exist then add the route using add route command.

    Note:- you might get this error if you have two default routes. Check the show route output and delete one route after confirming from the customer.
  3. Alternatively, you can also create a Net profile with the SNIP that you configired and then Bind it to Service / Service Group to make sure that monitor probes are initiated with that SNIP .
