local For non-IP packets, is the source Ethernet MAC address of
transmitted packets and the destination Ethernet MAC address of
received packets. On a non-bridged WAN connection, the two
MAC addresses will be all zeros.
Local for IP protocols, is the IP source address of transmitted
packets and the IP destination address of received packets. In the
case of TCP or UDP, it will also include the TCP or UDP port
number ([IP-address];[port]).
direction An arrow “<-”, “->” showing the direction (receive and send
respectively) in which the packet was traveling.
remote For non-IP protocols, has the same format as “local” non-IP
packets but shows the destination Ethernet MAC address of
transmitted packets and the source Ethernet MAC address of
received packets.
For IP protocols, has the same format as <local> but shows the IP
destination address of transmitted packets and the IP source
address of received packets.
length The length of the packet in octets (8-bit bytes).
frag Used if the packet has a non-zero IP offset or the IP More-
Fragments bit is set in the IP header.
log Used to report one or more messages based upon the packet status
or packet header flags. The packet status messages include:
• corrupt, where the packet is internally inconsistent
• unreach, where the packet was generated by an “unreach=”
rule in the firewall
• !pass, where the packet was blocked by the data firewall
• bringup, where the packet matches the call firewall
• !bringup, where the packet did not match the call firewall
• TCP flag bits that will be displayed include syn, fin, rst.
• syn is only displayed for the initial packet which has the SYN
flag and not the ACK flag set.
tag Contains any user defined tags specified in the filter template used
by SAM.
