You can logically subdivide the internal LAN for a HiperSockets™ CHPID into
multiple virtual LANs (VLANs).
Procedure
Perform the following steps to configure one or more
VLANs for a single HiperSockets CHPID:
- Configure the interfaces. Configure each IPv4
interface for this HiperSockets CHPID in the TCP/IP profile using the INTERFACE statement for IPAQIDIO,
rather than the DEVICE, LINK, and HOME statements.
Configure each
IPv6 interface for this HiperSockets CHPID in the TCP/IP profile using the INTERFACE statement for IPAQIDIO6.
- Configure a VLANID value on each IPv4 INTERFACE statement
and each IPv6 INTERFACE statement on this stack for this HiperSockets CHPID. Within
each IP version, these VLANID values must be unique.
- Configure a unique subnet for each IPv4 interface for this HiperSockets CHPID, using
the subnet mask specification on the IPADDR parameter on the INTERFACE
statement.
- If you are using OMPROUTE and OMPROUTE is not configured
to ignore this interface, ensure that the subnet mask value that you
configure on the INTERFACE statement in the TCP/IP profile matches
the subnet mask that is used by OMPROUTE for this interface. The subnet mask that OMPROUTE uses is the subnet mask value that
is defined on the corresponding OMPROUTE statement (OSPF_INTERFACE,
RIP_INTERFACE, or INTERFACE) for this interface. If no OMPROUTE statement
is specified for this interface, the subnet mask that OMPROUTE uses
is the class mask for the interface IP address.
- Ensure that you understand the fixed storage requirements
for this configuration. Each interface requires its own
DATAPATH device, and each DATAPATH device requires fixed storage for
read processing. For more information, see Fixed storage requirements for OSA-Express QDIO and HiperSockets interfaces
