Hi,
For some time now there was messages messing my logs on UBR 7246:
%UBR7200-3-ZEROMAC: Error: Mac addr is zero sent to CMTS cmts_tables_add: Cable4/0 IP XX.YY.ZZ.VV SID 104!
and naturally then:
%IP-4-ZERO_ADDR: Zero MAC address for XX.YY.ZZ.VV in ARP cache
Users with that sids are legit computers free of wiruses etc. Zero MAC is sent usually after computer with that IP goes down.
I didn't find any command to block zero MACs from getting into ARP table, and as seen UBR doesn't prevent it either.
Any ideas? Maybe someone did manage to prevent this from happening?
Thanks!
John
