ICMP Group

This group contains the Internet Control Message Protocol (ICMP) input and output
statistics. ICMP messages are used for out-of-band messages related to network
operation. This group is implemented per RFC1213.

Table 19-4. TCP Group OIDs

Algorithm used to determine the timeout value used for
retransmitting unacknowledged octets. The CDM-570/570L uses
Van Jacobson's algorithm.
Minimum value permitted by a TCP implementation for the
retransmission timeout. The CDM-570/570L uses a minimum
timeout of 1000 milliseconds.
Maximum value permitted by a TCP implementation for the
retransmission timeout. The CDM-570/570L uses a maximum
timeout of 64000 milliseconds.
Limit on the total number of TCP connections the entity can
support. In the CDM-570/570L , the maximum number of
connections is dynamic so a value of –1 is returned.
