A broadcast/multicast address is normally not present in the Ethernet frame‟s SA field, however,
such frame may be generated by a test gear or it may occur due to a network fault. Although
both "LAN" and "WAN" MAC tables would learn a multicast SA address (the "WAN" table would
also learn a broadcast SA address) which would eventually age out, that does not affect normal
operation because both multicast and broadcast frames are always broadcast (see Routing
column). Note that multicast/broadcast addresses may also be accidentally entered as static
MACs.
2
If QVLAN filtering is enabled (see Port Details tab).
3
Normally affects a Passed counter; however, if discarded due to abundance of higher priority
traffic, it affects a Lost one.
4
Unlikely scenario because the two local MAC tables share the same aging time.
