IP length (as specified in packet header) was greater
than payload received in the Ethernet packet. This
would indicate the packet was truncated before
arriving.
Dropped - Bad IP Version
Total Dropped IP Version 6 Packets (
IP Module only
supports IP Version 4).
Dropped - TTL Expired Total Dropped Packets due to Time To Live counter
expired (TTL limits the number of hops, or seconds,
before a packet reaches it’s destination).
Dropped - No Route Total Dropped Packets due to no Route for the
destination in the
IP Module Route Table. These are
packets that are directed to the
IP Module’s MAC
address and the
IP Module will reply to the sender with
a ICMP ‘Destination net unreachable’ message.
Dropped - No ARP Entry
Total Dropped Packets due to no ARP entry in
IP
M
odule ARP Table. For example, if a IP Module
receives packets from the satellite for a host that is not
in the ARP table, the
IP Module will send an ARP
request. If there is no response, the packets will be
dropped.
