I have an x670-48x in a stack with another x670-48x.
When I look at sh iparp it says 8192 dynamic entries and 8192 max ARP entries. So I am maxing it out right?
The output from sh iproute reserved-entries statistics says 4144 IPv4 Hosts on one switch and 4144 IPv4 Hosts on the other switch. The max listed in the table below is 8189.
So what are my options to get more ARP entries? What side affects of this being max'ed out should I be seeing?

the "sh iparp" command doesn't give you a view of the hardware usage, this is a software view. It is important to keep the iparp max_entries above the actual network size.
To know the HW usage, you need to enter that command: sh iproute reserved-entries statistics
This will tell you all your L3 HW table usage. Hard to comment without seeing the output. You'll not exceed the HW limit, but we can optimize the resource to help maximize it. EXOS will also help you by installing active entries in priority, but at one point in time you'll need to change the design or the devices if you need more ARP.
