The STATIC ROUTING information is maintained in four tables: (1) the SUBNET table (2) the ROUTER table (3) the DEFAULT ROUTER table (4) the DESTINATION SUBNET table Use the 'A' (again) and 'M' (more) commands to view the tables. 'Again' repeats the current screen, 'More' displays the next screen. A null command defaults to 'More'. The 'More' command is not listed if the current screen is the last screen. SET command defines a new table entry or changes a table entry, depending on the particular table (see individual table descriptions). The DELETE command deletes an entry from a table. The SET and DELETE commands require parameters. If you are not sure of the syntax, just type the SET or DELETE command and you will be prompted for all the relevant parameters. The expert user who knows the syntax can type the command followed by the parameters, thus bypassing the prompt messages. $ The fields marked with a '*' in the table headers are the fields that must be specified in SET commands.

A station is usually part of only one subnet and therefore has one entry in the subnet table. Stations with several entries in the subnet table are usually routers. Subnets can't be added to or deleted from the subnet table, but some of the characteristics of a subnet can be altered via the SET command: LIFETIME: AFI: SUBNET NO: The subnet no defines the local subnet number. All NSAP addresses with this subnet number are considered to be local and can be reached without going through a router or default router. $$ DEFAULT ROUTER TABLE -------------------- If a default router is defined, this station will forward to it all frames with a remote subnet number in the destination NSAP. Unless there are several routers on the local subnet, defining a default router is sufficient to establish addressability of remote subnets. Only zero or one default routers can exist. $$ ROUTER TABLE ------------ A ROUTER TABLE entry defines the existence of a router. Together with the DESTINATION SUBNET table, it defines how to forward frames to remote subnets. If only one router exists, it makes sense to define only a default router. The following parameters must be specified in a SET ROUTER command: ROUTER NAME: arbitrary ASCII name used to refer to this router in a DELETE ROUTER or a SET DESTINATION-SUBNET command SUBNET NAME: must be one of the subnet names seen in the SUBNET TABLE SUBNET ADDRESS: in standard iNA960 802.3 / 802.4 subnets, this is the 6 byte MAC address followed by FE. A ROUTER TABLE entry serves no useful purpose until one or more DESTINATION SUBNET TABLE entries refer to it. $$ DESTINATION SUBNET TABLE ------------------------ This table defines which remote subnets can be reached through which routers. The router must be identified by its router name, as defined in the ROUTER table. $$ Further help can be obtained on the following topics (enter any unambiguous abbreviation): SUBNET-TABLE DEFAULT-ROUTER ROUTER DESTINATION-SUBNET TOPICS
