On this page you can check boxes for additional, IFCONFIG configuration parameters. The default is that none of the additional parameters are checked. The default settings are adequate for most installations. When you exit the TCP/IP Configuration Notebook, any information that you specified on this page will be retained in the SETUP.CMD file.
The selections on this page are:
Check this box to disable all-routes broadcast.
Uncheck this box to enable all-routes broadcast. This is the default.
Check this box to disable Address Resolution Protocol (ARP) mapping between internet addresses and Ethernet addresses or IBM token-ring addresses.
The default is to enable ARP mapping.
Check this box to enable TCP/IP to add routes obtained by ICMP redirects. Internet Control Message Protocol (ICMP) redirects are messages from a router requesting that a host optimize routing by changing its routes.
Check this box to disable sending of token-ring headers with the extended snap format.
Extended snap format is an IEEE standard and must be enabled if you want to communicate with computers that use the extended snap format, such as AIX computers.
The default is to enable sending of token-ring headers with the extended snap format.
Check this box to disable routing field support.
The default is to enable routing field support.
Check this box to enable trailer encapsulation.
Trailer encapsulation minimizes the number of memory-to-memory copy operations a receiver must perform.
On networks that support the Address Resolution Protocol (ARP), selecting -trailers indicates the system should request that other systems use trailer encapsulations when sending to this host.
Uncheck this box to disable trailer encapsulation. This is the default.
Check this box to enable the Ethernet IEEE 802.3 protocol.
Uncheck this box to disable the Ethernet IEEE 802.3 protocol and enable the Ethernet DIX 2 protocol. This is the default.
Check this box to indicate that the medium access control (MAC) address in Address Resolution Protocol (ARP) packets on this token-ring network are in the canonical IEEE 802.5 format.
Uncheck this box to indicate that the MAC addresses in ARP packets on this token-ring network are in the non-canonical format. This is the default.
