Description
The number of ICMP Parameter Problem messages sent.
The number of ICMP Source Quench (buffer almost full, stop sending data) messages
received.
The number of ICMP Source Quench (buffer almost full, stop sending data) messages
sent.
The number of ICMP Redirect messages received.
The number of ICMP Redirect messages sent. For a host, this object will always be zero,
since hosts do not send redirects.
The number of ICMP Echo (request) messages received.
The number of ICMP Echo (request) messages sent.
The number of ICMP Echo Reply messages received.
The number of ICMP Echo Reply messages sent.
The number of ICMP Timestamp (request) messages received.
The number of ICMP Timestamp (request) messages sent.
The number of ICMP Timestamp Reply messages received.
The number of ICMP Timestamp Reply messages sent.
The number of ICMP Address Mask Request messages received.
The number of ICMP Address Mask Request messages sent.
The number of ICMP Address Mask Reply messages received.
The number of ICMP Address Mask Reply messages sent.
Description
The total number of segments received, including those received in error. This count
includes segments received on currently established connections.
The total number of segments sent, including those on current connections, but excluding
those containing only retransmitted octets.
The algorithm used to determine the timeout value used for retransmitting
unacknowledged octets.
The limit on the total number of TCP connections the entity (the switch) can support. In
entities where the maximum number of connections is dynamic, this object should
contain the value -1.
The minimum value permitted by a TCP implementation for the retransmission timeout,
measured in milliseconds. More refined semantics for objects of this type depend upon
the algorithm used to determine the retransmission timeout. In particular, when the
timeout algorithm is rsre (3), an object of this type has the semantics of the LBOUND
quantity described in RFC 793.
The maximum value permitted by a TCP implementation for the retransmission timeout,
measured in milliseconds. More refined semantics for objects of this type depend upon
the algorithm used to determine the retransmission timeout. In particular, when the
timeout algorithm is rsre (3), an object of this type has the semantics of the UBOUND
quantity described in RFC 793.
The number of times TCP connections have made a direct transition to the SYN-SENT
state from the CLOSED state.
The number of times TCP connections have made a direct transition to the SYN-RCVD
state from the LISTEN state.
