Obtain DNS
server from
DHCP
DNS is an internet service that translates domain names into IP addresses.
It is also needed for the instrument to find and display its hostname
assigned by the network.
Check this item to obtain the DNS server address
from DHCP. You must have previously checked Get IP Address
Automatically.
DNS server This value is the address of the DNS server. It is used if you are not using
DHCP or if you need to connect to a specific DNS server.
Enable TCP
Keepalive
Check the Enable box to enable the TCP keepalive function. The instrument
uses the TCP keepalive timer to determine if a client is still reachable. If
there has been no activity on the connection after the specified time, the
instrument will send keepalive probes to the client to determine if it is still
alive. If not, the connection will be marked as down or "dropped." The
instrument will release any resources that were allocated to that client.
Timeout This is the delay in seconds before TCP keepalive probes will be sent to the
client. It is recommended that the largest value be used that still meets the
application's need for unreachable client detection. Smaller keepalive time-
out values will generate more keepalive probes (network traffic), using more
of the available network bandwidth. Allowed values: 720 - 99999 seconds.
