Command Descriptions, Continued
“config address ip” command
“config device id” Command
This command configures the hub-half IP address. Each individual hub board (“hub-half”) in the system must have a unique IP address. Your network administrator can help you choose appropriate addresses for your DataNET hubs. IP addresses are entered in “dotted-decimal” nota- tion. For example:
config address ip 192.10.6.123
The IP address is automatically stored in the hub-half’s non-volatile memory when you enter this command. You can display the current IP address with the config display command.
Each pair of hub boards shares a common “device ID.” This ID must be configured into each board’s non-volatile memory at installation time with the config device id command. Device Ids have the same form as IP addresses (i.e., four dotted-decimal components, in the range 0 through 255). Any value may be chosen for device IDs. The only requirements are that each pair of hub boards that make up a complete hub, share the same device ID and that device IDs are not duplicated between any hubs in a single DataNET.
One convenient convention for assigning device IDs is to use the IP ad- dress of the “A” half of each pair as the device ID.
“config display” Command
“config netmask” Command
This command displays the settings for the hub’s non-volatile configura- tion parameters.
This command sets the IP subnet mask for a hub-half. Your network ad- ministrator can help you choose an appropriate subnet mask for your DataNET hubs (subnet masks are not always required). Subnet masks are entered in “dotted-decimal” notation. For example:
config netmask 255.255.192.0
The subnet mask is automatically stored in the hub-half’s non-volatile memory when you enter this command. You can display the current sub- net mask with the config display command.
