3. List the current access list.
Syntax:
list tcpip
If the list is empty, all hosts have access to the NIC services. If
there are entries in the list, only those hosts specified have
access to printing and remote command execution.
To add and delete access list entries, the commands are:
Syntax:
store tcpip tcp access add|del hostIPaddress|
networkaddress
reset
where hostIPaddress is the IP address of a TCP/IP host on
your network and networkaddress is the address of a subnet on
your network.
Example:
store tcpip tcp access add 192.75.11.25
store tcpip tcp access add 192.75.12.0
store tcpip tcp access del 192.75.11.25
reset
NOTE: Although the maximum number of entries in the access list
is 10, each entry can refer to a network rather than a
specific host. This allows all hosts on that specified network
and any individual hosts specified in the list to have access.
