Description
This field sets the time before which the server discards an
incomplete IP datagram.
When selected, this option instructs the system not to respond to
Internet Control Message Protocol (ICMP) echo requests.
This field specifies the maximum IP packet size in use when
transmitting to a different subnet. The valid range is 68 to 9600
bytes. For IPv6 traffic, the effective MTU is 1280 bytes when this
option is configured to be less than 1280.
When selected, this option instructs the system to send a keep
alive packet when it has received no data or acknowledgment
packets for a connection within the specified timeout period.
This field specifies the number of seconds to keep alive a
connection.
This field specifies the size of the maximum transmission unit
(MTU) in use for TCP packets when transmitting to a locally
configured subnet. The valid range is 68 to 9600 bytes. For IPv6
traffic, the effective MTU is 1280 bytes when this option is
configured to be less than 1280.
This field specifies the size of the MTU for protocols other than TCP
when transmitting to a locally configured subnet. The valid range
is 68 to 9600 bytes . For IPv6 traffic, the effective MTU is 1280
bytes when this option is configured to be less than 1280.
