Use the Connection Properties window to set up the connection properties
of a LAN, OSA, or VSWITCH connection.
Fields
After you have set these properties, you'll be able to choose this
connection in the networking properties of server complexes.
The fields
in this window show:
- z/VM information about the connection. This information is read-only.
- Linux networking definitions. You can edit this information.
The
Connection Properties window contains

- For an OSA, the displayed fields are:
- Type – OSA
- CHPID – Channel Path ID of the OSA
- Base Real Device – base real device number of the OSA
- Maximal Real Device – maximal real device number of the OSA
- LAN Information
- For a LAN, the displayed fields are:
- Type – LAN
- IO Protocol – IO protocol of the guest LAN. Possible values are QDIO for
QDIO guest LANs and HIPERS for Hipersocket guest LANs
- LAN Name – name of the guest LAN
- LAN Owner – name of the owner of the guest LAN
- Maximal Frame Size – maximal frame size allowed in the guest LAN
- VSWITCH Information
- For a VSWITCH, the displayed fields are:
- Type – VSWITCH
- VSWITCH Name – name of the guest VSWITCH
- Maximal Frame Size – maximal frame size allowed in the VSWITCH
- OSA Real Devices – list of the OSA real devices to which the VSWITCH
is attached
Linux Networking Definitions
- MTU
- (Mandatory) Type an integer representing the maximal transmission unit.
For a guest LAN, this number should not be larger than the maximal frame size
(shown in the z/VM information at the top of the window).
- Base IP Address
- (Mandatory) Type the lowest IP address to be used when assigning an IP
address to a Linux guest system that is
configured on this connection. The Base IP Address and the IP Address
Range define the pool of IP addresses for this connection. The available
IP addresses are those between Base IP and Base IP + range -1, which are not
included in the Occupied IP Addresses list.
- IP Address Range
- (Mandatory) Type the number of IP addresses, starting from Base IP
Address, which can be used for assigning an IP address to a Linux guest system that
is configured on this connection.
- Netmask
- (Mandatory) Type the subnet mask, to be used for the Linux routing configuration.
- Default Gateway
- (Optional) Type the default gateway for the connection.
- Occupied IP Addresses Table
- The list of occupied IP addresses in the range. The list includes both
entries that were automatically added and entries that you can add manually.
(Occupied IP addresses are added automatically when you click Action → Scan
for Occupied IPs in the z/VM Networking window and when you configure
the network properties of Linux guest systems
on this connection) Double-click a line in this table to open the Occupied
IP Address Properties window for the selected IP address.
- IP Address (in the Occupied IP Addresses Table)
- The occupied IP address.
- Guest (in the Occupied IP Addresses Table)
- (Optional) The Linux guest system that
owns the occupied IP address.
- Interface (in the Occupied IP Addresses Table)
- (Optional) The network interface name at the above Linux guest system.
- Add
- Opens the Occupied IP Address Properties window and lets you add an entry
to the list of Occupied IP Addresses.
- Edit
- Opens the Occupied IP Address Properties window and lets you edit the
selected entry in the Occupied IP Addresses list. This button is only
enabled if exactly one entry is selected.
- Remove
- Removes the selected entries in the Occupied IP Addresses list.
This button is enabled if at least one entry is selected.
