Total Dropped Packets
Dropped - Bad IP Header
Checksum
Total Dropped Packets due to incorrect IP Header
Checksum.
Dropped - Bad Buffer
Length
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 M
odule 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 M
odule Route Table. These are
packets that are directed to the
IP M
odule’s MAC
address and the
IP M
odule 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 M
odule
receives packets from the satellite for a host that is not
in the ARP table, the
IP M
odule will send an ARP
request. If there is no response, the packets will be
dropped.
