Ip_Forward_Broadcast; Ipso_Class; Ipx_Do_Checksum - Nortel 2000 Software Reference Manual

Book C Chapter 2 Configuration Parameters

ip_forward_broadcast

This Annex parameter allows an Annex to broadcast a packet to the SLIP
or PPP interfaces. When the Annex receives a packet sent to a broadcast
address (except 0.0.0.0 and 255.255.255.255), it scans the list of installed
interfaces and matches the broadcast address against the interface's
remote address using a subnet or net mask. If these addresses match, the
Annex copies the packet to that interface. When disabled, the Annex does
not scan the interface list and does not copy broadcast packets. A Y
enables this parameter, an N disables it. The default is N.

ipso_class

This asynchronous port parameter specifies the U.S. Department of
Defense basic IP Security Option (IPSO) classification level included in
TCP packets generated locally on Annex CLI, dedicated, or adaptive
asynchronous ports.
The option is not added to locally generated ICMP messages, RIP
updates, or other system packets. The Annex does not check incoming
packets for the presence of the IPSO. Valid options for the classification
level are topsecret, secret, confidential, unclassified, and none. If you
specify none, no IPSO classification is added. The default is none.

ipx_do_checksum

This Annex parameter controls whether or not the Annex enables an IPX
checksum. A Y enables this parameter, an N disables it. The default is N.
