Caveats

Under certain circumstances, E-series cards might learn invalid MAC addresses and temporarily lose
well-known/static addresses, possibly resulting in high flood rates. This issue can occur when traffic
flows through an E-series card and there are no MAC addresses currently in the MAC table for that
E-series card (for instance, after you have cleared the complete MAC table, or when the node is just
coming up). The chipset can cause the E-series card to learn invalid addresses in this scenario under high
rates of flood traffic (multicast, broadcast, unknown) or PHY interface noise. Side-effects of clearing the
MAC table when traffic is flowing can cause the E-series card to lose well-known/static MAC addresses
along with dynamically learned MAC addresses. This can cause high flood rates (multicast, broadcast,
unknown) possibly reaching the limitation described in the following field notice:
