HP UX 11i v2 Networking Software manual Lanadmin Commands, Level information for a given ipoibppa

Checking the IPoIB Interface Status To check the current status of the IPoIB interface.

Syntax and example: ifconfig lan9000

Output Example:

lan9000: flags=842<BROADCAST,RUNNING,MULTICAST>

inet 192.32.32.255 netmask ffffff00 broadcast 192.32.32.255

Enable the IPoIB Interface To enable the IPoIB interface.

Syntax: ifconfig <ipoib_interface> [address] [netmask] up

Example: ifconfig lan9000 192.32.32.255 up

There is no direct output from this command.

To confirm that the interface is UP, run the ifconfig lan9000 command again Output Example:

lan9000: flags=843<UP,BROADCAST,RUNNING,MULTICAST>

inet 192.32.32.255 netmask ffffff00 broadcast 192.32.32.255

Disable the IPoIB Interface To disable the IPoIB interface.

Syntax: ifconfig <ipoib_interface> [address] [netmask] down

Example: ifconfig lan9000 192.32.32.255 down

There is no direct output from this command.

To confirm that the interface is DOWN, run the ifconfig lan9000 command again Output Example:

lan9000: flags=842<BROADCAST,RUNNING,MULTICAST>

inet 192.32.32.255 netmask ffffff00 broadcast 192.32.32.255
