Добрый день!

Да... счетчики растут.

debug driver ... даже с no ipv6 enable, обрабатывает ns-na... 

 

packet received:type=NS-NA,vlan=11,port=28,pktlen=90,reason=0x0,
reasons=0x00002000 00000000 00000000 ,
srcmac=38:4f:49:92:b9:30,  dstmac=33:33:ff:1c:13:01.
Packet data of first 64 bytes:

Это особенность работы именно SNR-S2960-24G, CPU не отвечает на пакеты ipv6-протоколов, но все еще копирует их. Например, на SNR-S2985G-24T значение счетчика NS-NA не растет при "no ipv6 enable".
