Is there a limit on the icmp pakets size?

L3 Networker


We try to make ping throw a PAN-4020 device, whene we try with a 1023 byte pakets it works, but wehen we try with a 1024 byte pakets this is rejected by the PAN. Is there any limit on the icmp paket size?

Also, whene we activate the jumbo frame mode on the device, is there any impact on traffic or on the function of the device (reboot required,...)

If you have configured "Zone Protection", one of the check boxes limits the maximum size of PING packets. Without zone protection there is no limit.
