boa tarde,
Verificando lentidão na rede, percebi que existe muitos pacotes arp sendo
gerados. Então instalei Arpwatch para monitorar e está aparecendo
constantes nos logs essas mensagens:

f0:25:72:e:be:98 (0:0:c:7:ac:1) eth1

May 18 13:35:44 localhost arpwatch: ethernet mismatch 10.48.0.23
f0:25:72:e:be:98 (0:0:c:7:ac:1) eth1
Pesquisando encontrei uma das possíveis causas, mas ainda não sei como
resolver essa situação:
ethernet mismatch
The source mac ethernet address didn't match the
address inside the arp packet.
