I have a Mac OS Machine that I've set up a LACP connection with a cisco SG300.

When using the lag connection I can only ping certain IP addresses for some strange reason.
When I disable the lag connection I can ping all addresses fine. I can also ping remote IP addresses fine when connected.
8.8.8.8 yes - google
192.168.16.2 no - vsphere vm (dns)
192.168.16.28 yes - vsphere vm
192.168.16.3 no - physical device (backup dns)
I see no correlation between why some addresses respond and others do not. I've tried disabling all the firewalls. Of course all these IP's respond when using a different connection.
I've tried arp -a
. it shows these ips on the network.

One other thing I noticed is that the connection can ping all addresses if I remove one of the connections.
tried clearing arp cache. tried restarting mac and cisco.
