Use nwmgr instead. It is much more powerfull than lanscan and as you can see in the example below, you can obtain a lot of more info about the network interfaces.host# nwmgrName/ Interface Station Sub- Interface RelatedClassInstance State Address system Type Interface============== ========= ============== ======== ============== ========lan2 UP 0x001E0B45E09A igelan 1000Base-SXlan0 UP 0x001E0B45E09C igelan 1000Base-SXlan1 UP 0x001E0B45E09D igelan 1000Base-SXlan3 UP 0x001E0B45E09B igelan 1000Base-SXhost# nwmgr -q info -c lan0lan0:Interface State =UPMAC Address = 0x001E0B45E09CSubsystem = igelanInterface Type = 1000Base-SXHardware Path = 0/1/1/0NMID = 2Feature Capabilities = Physical InterfaceIPV4 Recv CKOIPV4 Send CKOVLAN Tag Offload64Bit MIB SupportIPV4 TCP Segmentation OffloadUDP Multifrag CKOFeature Settings = Physical InterfaceVLAN Tag Offload64Bit MIB SupportMTU = 1500Speed = 1 Gbps Full Duplex (Autonegotiation : On)lan0 PCI properties:PCI Sub-System ID = 0x1701lan0 driver properties:Driver Version = B.11.31.0803Driver State = IGELAN_ONLINE

how to show network interface information in HP/UX

Description

To show network interface information in HP/UX:

# landiag

OR

# lanscan

OR

# netstat -in
