FortiGate MAC address storage capacity

Hi, I was trying to find information about MAC address table size for some FortiGates (more specifically 100F, 200F, 500E and 600E). This information is not available on the datasheet and I'm wondering if there any other source available that could have this?

Yes, there is:
for FortiOS 6.0.11 and 6.4.3
100F, 500E, 600E: 10K (10.240)
No info on 200F yet, but I assume it's 10K.
 
Here's where you get this kind of info - the Maximum Values tool
https://docs.fortinet.com/max-value-table
 
select FortiOS version, one or more FGT models, choose "Show all", and search for "system.arp-table".
Very nice tool, Fortinet! Thanks a lot.
 
HTH.

I assume you meant 1000 and not 10K if we  are talking mac address table and not arp.table.
 
system.mac-address-table: 0 1000 0
 
vrs
 
system.arp-table: 0 10240 10240

hi Ken,
 
nice to hear from you.
I'd love to learn how these values differ. I thought the only purpose of a MAC address table would be to cache arp responses...

Thanks a lot for the answer, this was exactly what I was looking for.
To answer the question below about MAC table vs ARP table, the MAC table pretty much works at L3, it's an MAC:IP mapping table and the ARP table works at L2, it's an MAC:Physical interface mapping. Hope that helps clarify.
