To display the network interface cards and status

# lanscan  Hardware Station        Crd  Hdw   Net-Interface    NM   MAC       HP-DLPI DLPI  Path     Address        In#  State NamePPA          ID   Type      Support Mjr#  0/0/0/0  0x00306E1CC281 0    UP    lan0 snap0       1    ETHER       Yes   119  1/12/0/0 0x00306E210F32 3    UP    lan3 snap3       2    ETHER       Yes   119 

To configure the NIC cards such as speed, MTU, etc..

# lanadmin (it is a interactive tool) 

To find out the speed of duplex setting of lan0

# lanadmin -x 0  Speed = 1000 Full-Duplex.  Autonegotiation = On. 

To list all the configured interfaces and IP addresses

# netstat -in 

To force HP-UX to use specific interface card

# traceroute -i lan2 10.20.30.40  

HP-UX stores network interface configuration information on /etc/rc.config.d/netconf file

# cat /etc/rc.config.d/netconf  HOSTNAME="it-hp49"  OPERATING_SYSTEM=HP-UX  LOOPBACK_ADDRESS=127.0.0.1  INTERFACE_NAME[0]="lan0"  IP_ADDRESS[0]="216.131.195.137"  SUBNET_MASK[0]="0xffffff00"  BROADCAST_ADDRESS[0]="216.131.195.255"  INTERFACE_STATE[0]=""  DHCP_ENABLE[0]=0   ROUTE_DESTINATION[0]="default"  ROUTE_MASK[0]=""  ROUTE_GATEWAY[0]="216.131.195.10"  ROUTE_COUNT[0]="1"  ROUTE_ARGS[0]="" 

To add a alias address to lan0, add the network information to /etc/rc.config.d/netconf file

INTERFACE_NAME[0]=lan0:1  IP_ADDRESS[0]=216.131.195.138  SUBNET_MASK[0]=255.255.255.0  BROADCAST_ADDRESS[0]=""  INTERFACE_STATE[0]=""  DHCP_ENABLE[0]=0  INTERFACE_MODULES[0]="" 

Restart the network service

/sbin/init.d/net start 

Network Tracing and Logging

The nettl command is a tool used to capture network events or packets. 

Initialize the tracing/logging facility:

# nettl -start 

Display the status of the tracing/logging facility.

# nettl -status all 

nwmgr (Network Interface Management)

The nwmgr program is the unified command to administer all HP-UX LAN and RDMA interfaces. This command can be used to:

• Display information of an interface
• Modify settings of an interface
• Reset the interface or its statistics
• Diagnose link connectivity
• Create and set configuration information for a component simultaneously
• Delete or erase components

# nwmgr   Name/          Interface Station          Sub-   Interface      Related ClassInstance  State     Address        system   Type           Interface ============== ========= ============== ======== ============== ========= lan2           DOWN      0x001A4B096828 iether   1000Base-T lan0           UP        0x001A4B097F9A iether   1000Base-T lan1           DOWN      0x001A4B097F9B iether   1000Base-T 

# nwmgr --help -S all  # lists all the subsystems  # nwmgr --help -S subsystem # display subsystem specific usage 

To View Interface attributes

# nwmgr  -A all -c lan0 lan0 current values:    Link State = Up    Speed = 1 Gbps Full Duplex (Autonegotiation : On)    MTU = 1500    MAC Address = 0x001a4b097f9a    Receive Flow Control = On    Transmit Checksum Offload = Off    Receive Checksum Offload = Off    Virtual MTU = 0       TCP Segmentation Offload is now disabled.

To get interface statistics for interface lan0

# nwmgr --st all -c lan0 

To View interface details

# nwmgr -q info -c lan0 

To get interface vital product data

# nwmgr -q vpd -c lan0 

To set interface attributes

# nwmgr -s -A attr1-value, attr2=value ... -c lan0 

Reset statistics for an interface

# nwmgr -r --st -c lan 

Some nwmgr Syntax and their Equivalent lanadmin and linkloop Syntax are given bellow

nwmgr -S vlan

lanadmin -V scan nwmgr -c lan5000

lanadmin -V info 5000 nwmgr -a -S vlan -A vlanid=10, ppa=1

lanadmin -V create vlanid 10 1 nwmgr -s -c lan5000 -A vlanid=20

lanadmin -V modify vlanid 20 5000 nwmgr -d -c lan5000

lanadmin -V delete 5000 nwmgr --cra -c lan5000

lanadmin -p 5000 nwmgr --diag -c lan5000 -A dest=0xaabbccddeeff linkloop -i 5000 0xaabbccddeeff
