maximum number of DHCP reservations RBR850

For those of you with large reservation lists and complex networks, i'd thought i would share the current max DHCP reservations you can have on an RBR850 based set up. I currently run 1x RBR850 and 2x RBS850s and am on the last stable firmware i have tried -  V4.6.7.5_2.1.7

 

A year ago I had hit the limit of 113 entries before additional entries caused corruption of prior entries in a classic stack-overflow firmware bug. Running firmware V4.6.7.5 i can enter 227 reservations but if you try to enter number 228, then the whole list vanishes before your eyes. Just hope you backup your settings before you find that out yourselves.

 

Hence, the DHCP reservation table maxes out at 227 entries currently and whereas i think that's likely good for most folks, I guess it wasn't quite enough for me, but i'll probably make do.

 

Happy to hear if anyone hears of a stable upgrade to address that limit of course, or if the firmware folks can up teh amount of table space again.
