Setting the network parameters
Via the
netpar -x
command, you can retrieve information on the current network parameters (e.g.
the IP address and port), which you can then change.
When assigning the IP address and setting up the network, observe the current state-of-the-
art technology for securing and segmenting corporate networks. Interflex recommends
operating all installed components and servers in
one
VLAN.
