Ditto for the MAC.

15w4d: %SEC-6-IPACCESSLOGP: list vlan40in denied tcp 1.1.1.51(22325)
(Vlan40 0000.0000.5349) -> 203.154.206.18(67), 1 packet
15w4d: %SEC-6-IPACCESSLOGDP: list vlan40in denied icmp 1.1.1.229
(Vlan40 0000.0000.5349) -> 203.154.206.18 (8/0), 1 packet
15w4d: %SEC-6-IPACCESSLOGS: list vlan40in denied 203.154.206.18 1 packet

Looking at those, I'd wager a guess that "IPACCESSLOGS" means something
like "self-originated packet" or so (source IP 127.0.0.x), and it will
only log the destination IP in these cases.

Anyone curious enough to check the IOS sources...? :-)

(I'd consider it a bug, if it were so :-))
