LANDFVID - Default VLAN ID
This is the VLAN ID that will be used when no VLAN ID is
specified on a GRANT for an ACCESS port. Depending on the
porttype, traffic on the default VID may or may not be
delivered to the guest tagged. (INGRESS rule).
There is no default VLAN ID for a virtual switch created
as DEFINE VSWITCH VLAN AWARE. In this case LANDFVID is
set to x'8000'- thus indicating no default LAN ID
assigned.

LANIPTBL - Pointer to GALPL (hash table)
This IP Table functions as an "ARP Cache" for the

is the hash table that holds the unicast IP addresses.
Each entry (IPNBK) represents an IP Address, and holds
a pointer to the network device (NIDBK) which owns this
IP Address.
Notes :
Only unicast addresses should be installed in this
table. MAC addresses should be installed in the
Link ID Table (LANIDTBL) by MAC address.

LANNVID - Native VLAN
The Native VLAN is the VLAN for the untagged set. For a
trunk port on a VLAN AWARE VSWITCH, the guest MUST be
authorized for the native VLAN in order to receive
untagged traffic. All traffic on the Native VLAN is
delivered to the guest UNTAGGED (Ingress Rule).
There is no NATIVE VLAN ID for a virtual switch created
as DEFINE VSWITCH NATIVE NONE. In this case LANNVID is
set to x'8000'- thus indicating no default LAN ID
assigned.

and also no communication to sharing OSA connections
allowed. Mutually exclusive with VEPA ON.
- VEPA: Guest-to-guest traffic forwarded to external switch
where a firewall, ACL, etc. may reject it or send it
back via Reflective Relay. Requires OSA & partner
switch support. Mutually exclusive with ISOLATION ON
- VEB: ISOLATION OFF & VEPA OFF.
Default, and traditional mode. Guest-to-guest
traffic is allowed (subject to other filters, eg

VSWITCH Routing Table Anchor
LANRTBL is the logical address of the first page of
routing tables allocated for this LAN. Each page consists
of multiple table entries. Assignment of a table entry
occurs when coupling a virtual NIC to the LAN. The
table's function is to route outbound data destined to the
physical LAN to one of eight possible OSA Ports.

******** Start of Virtual Switch Controller Section
******** Also used for Management ID information.
The Virtual Switch Controller section of this structure is
serialized by a combination of LANLKWRD and LANCTLCK.
To reference these fields, the LANLKWRD must be held at
least SHARED.
To modify these fields, either:
1) Obtain the LANLKWRD EXCLUSIVE, or
2) Obtain the LANLKWRD SHARED and the LANCTLCK EXCLUSIVE.
The second choice allows access to the controller-
