[Beowulf] odd vlan issue

i got roped into troubleshooting an odd network issue. we have a mix
of cisco (mostly nexus) gear spread over our facility. on one
particular vlan it's operating as if it's a hub instead of switch.
has anyone seen this before? i bounced around the net, my issue
appears to be "unicast flooding", but the chief correction seems to be
adjusting the ARP/CAM timeouts. but that hasn't working.
i'm sure this is a loaded question given none of you can see the
network, but i'm grasping at straws to come up with a reason why this
what's weird is we have two dozen other vlans, which aren't affected.
i cannot locate a difference in the config on the switches.
any thoughts are appreciated at this point
