This document describes a standard for establishing virtual ethernet
adapters in the VIO Server environment. This standard is specific to
the numbering scheme used to identify the VLAN ID's of the virtual
ethernet adapters. The VLAN ID number is also referred to in the HMC as
the PVID number.
This document assumes there are two VIO servers in the environment
and the names of the VIO servers are represented by "*vio0" and
"*vio5".
The VLAN ID numbers will be three digit numbers, each digit
representing a different aspect of the underlying ethernet adapter.
3 Digit VLAN ID Number
|
First Digit
|
Second Digit
|
Third Digit
|
5: Boot/Service
6: Standby
7: Backup
8: Management
9: Intra-Frame
|
0: Gigabit
5: 10/100
9: Bus
|
0,2,4,6,8: VIO Server with even numbered hostnames
1,3,5,7,9: VIO Server with odd numberd hostnames
|
The first digit of the VLAN ID numbers associated with virtual
ethernet adapters will be used to represent a variety of adapter
purposes. Those purposes include boot, standby, backup, management, and
intra-frame communications.
- 500-599: boot/service
- 600-699: standby
- 700-799: backup
- 800-899: management
- 900-999: intra-frame
The third digit of the three digit VLAN ID number assigned to virtual
ethernet adapters associated with the VIO Server named *vio0 will end
with a number between 0 and 4.
Example: 500, 501, 502, 510, 520, 521, ...
The VLAN ID numbers assigned to virtual ethernet adapters associated
with the VIO Server named *vio5 will end with an odd number beginning at
5.
Example: 505, 506, 507, 515, 525, 526, ...
The second digit of the three digit VLAN ID sequence will represent the
adapter speed, gigabit cards will be represented by 0 thru 4, 10/100
adapters by 5 thru 8, and bus speed adapters by a 9. This digit may be
reconfigured as necessary.

An LPAR may have multiple adapters of a variety of types, for
example an LPAR that provides database services and is a member of an
HACMP cluster may have boot, standby, management, backup, and
intra-frame virtual adapters as follows:
- Gigabit adapter used for boot/service address
- Gigabit adapter used for standby address
- 10/100 backup adapter
- 10/100 management adapter
- 2 intra-frame adapters
