Configuring networks for system WPARs

Edit online

You can configure the network for a system WPAR using the -h flag or the -N flag for the mkwpar command or the chwpar command.

If you do not specify any network information when you create a system WPAR, and the name of the WPAR resolves to an IP address on the same network as any active global interface, the mkwpar command automatically configures the network for the WPAR. If the WPAR does not resolve, you can specify zero or more network configurations using the -N flag for the mkwpar command or the chwpar command. All network changes can be performed on active or inactive WPARs. The changes take effect immediately.

Each network requires its own instance of the -N flag. The -N flag specifies network configuration attributes, and is used to separate the attribute=value pairs by blank spaces. You can specify more than one -N flag to configure multiple IP addresses. For example:

mkwpar -n wpar_name -N interface=en0 address=224.128.9.3 \
netmask=255.255.255.0 broadcast=224.128.9.255 -N interface=en1 \ 
address=192.168.0.3 netmask=255.255.255.0 broadcast=192.168.0.255

To configure a system WPAR with a network address of 224.128.9.3 using the en0 interface for the global environment, run the following command:

mkwpar -n wpar_name -N interface=en0 address=224.128.9.3 \ 
netmask=255.255.255.0 broadcast=224.128.9.255

To configure a system WPAR with an IPv6 network address of fe80::200:254 using the en3 interface from the global environment, run the following command:

mkwpar -n wpar_name -N interface=en3 address6=fe80::200:254 prefixlen=64

You can also use the -N flag with the chwpar command to add additional networks on a previously defined system WPAR. To add a network, run the following command:

chwpar -N address=224.128.9.4 wpar_name

If you want to change the network settings for a system WPAR, use the address attribute to identify the network you want to change. For example, to change the netmask and broadcast address of the network at 224.128.9.3, run the following command:

chwpar -N address=224.128.9.3 netmask=255.255.255.128 \ 
broadcast=224.128.9.127 wpar_name
