| |
| | '''<nowiki>-net dump[,vlan=n][,file=filename][,len=maxlen]</nowiki>''' has been replaced by '''<nowiki>-object filter-dump,id=id,netdev=dev[,file=filename][,maxlen=maxlen]</nowiki>'''. Note that the new syntax works with netdev IDs instead of the old "vlan" hubs.

The new syntax allows different settings to be provided per NIC.
