Crash on firmware 8.1.5

Does anybody know this bug?
The 5400 SM is configured with NAT+DHCP enabled.
The crash happens every time I issue the “arp -a” command via telnet.

fixed in 8.2.1

Unfortunately I cannot use 8.2.1 since there is another bug with NAT (Out of buffers), even worst…
Too bad :cry: :cry:

this isnt fixed with 8.2.1. I am having the same issue…

Oh and I am not using NAT or DHCP!
