Clarification of NAT Statistics

We have a router running NAT with a NAT stats output as below (changing ip address info for security reasons). Cisco docs say the last stat of 68064 misses is

"Number of failed allocations from the pool.".

Would I be correct in thinking that this means

the pool was depleted and so a session could not be

created, as opposed to a translation miss, where a

translation is not in table and so is created ?

I.e. the single ip address for NAT is not enough ?

Re: Clarification of NAT Statistics

You would be correct. misses (with the small m) are failed allocations from a pool, such as when all addresses in a pool are already allocated.
