Received IP Options
Packets Number of IP Options packets received.
Dropped - Total 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 greate r
than payload received in the Ethernet packet. This
would indicate the packet was trun cated 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 MA C
address and the IP Module will reply to the se nder with
a ICMP ‘Destination net unreachable’ message.
Dropped - No ARP Entry
Total Dropped Packets due to no ARP entry in IP
Module 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.
