Networking information produced by commands is also peculiar to the vPar on which you've issued the command. Networking configuration of vPars is covered in Chapter 13. Let's take a look at the network interface on two different vPars configured on the same server. First let's look at the output of vPar cable1 with a hostname of cvhdcon3:

 # hostname  cvhdcon3  # netstat -I lan0  Name      Mtu  Network         Address         Ipkts   Ierrs Opkts   Oerrs Coll  lan0      1500 172.16.15.0     cvhdcon3        12785   0     11855   0     3  #  # netstat -in  Name      Mtu  Network         Address         Ipkts   Ierrs Opkts   Oerrs Coll  lan0      1500 172.16.15.0     172.16.15.36    12990   0     12052   0     3  lo0       4136 127.0.0.0       127.0.0.1       7616    0     7616    0     0  #  # 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  0x00306E06F6BA 0   UP    lan0 snap0     1   ETHER     Yes     119  # 

This output shows that lan0 is the network interface devoted to vPar cable1 on this server. The lanscan output shows that this interface has a hardware path of 0/0/0/0. This is on the Core I/O card that was configured as a component of the vPar when it was created with -a io:0/0. The LAN interface on the Core I/O card was not explicitly called out when cable1 was created because 0/0/0/0 is an implied component of the Core I/O card at 0/0.

Let's now take a look at the second vPar running on this server, called cable2 with a hostname of cvhdcon4:

 # hostname  cvhdcon4  # netstat -I lan1  Name      Mtu  Network         Address         Ipkts   Ierrs Opkts   Oerrs Coll  lan1      1500 172.16.14.0     cvhdcon4        3463    0     1603    0     2  #  # netstat -in  Name     Mtu  Network         Address         Ipkts   Ierrs Opkts  Oerrs Coll  lan1     1500 172.16.14.0     172.16.14.44    3819    0     1948   0     2  lo0      4136 127.0.0.0       127.0.0.1       916     0     916    0     0  #  # lanscan  Hardware Station        Crd Hdw   Net-Interface  NM  MAC       HP-DLPI DLPI  Path     Address        In# State NamePPA        ID  Type      Support Mjr#  0/10/0/0 0x00306E0653E8 1   UP    lan1 snap1     1   ETHER     Yes     119  # 

This output shows that lan1 is the network interface devoted to vPar cable2 on this server. The lanscan output shows that this interface has a hardware path of 0/10/0/0. The LBA of 0/10 was configured as a component of the vPar when it was created with -a io:0/10/. Unlike the LAN interface on the Core I/O card that was an implied component, this LAN interface is in a separate PCI slot and LBA and therefore had to be specified explicitly when the vPar was created.

Running lanadmin on cable1 produces more detailed output related to lan0, as shown in the following listing:

This lanadmin output shows lan0 as the configured LAN interface on cable1. Let's now run lanadmin on cable2 and see for what LAN interface it produces an output:

This lanadmin output shows lan1 as the configured LAN interface on cable2.

Producing information specific to the vPar in which you issue a command is what you can expect when working at the command line with vPars.

Next, let's take a look at a couple of GlancePlus/UX outputs.
