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.

Examples:

Adapter Speed

VLAN ID	Adapter Type	Adapter Speed	VIO Server
500	Boot 0	Gigabit	*vio0
501	Boot 1	Gigabit	*vio0
505	Boot 0	Gigabit	*vio5
506	Boot 1	Gigabit	*vio5
550	Boot 0	10/100	*vio0
551	Boot 1	10/100	*vio0
555	Boot 0	10/100	*vio5
556	Boot 1	10/100	*vio5
590	Boot 0	Bus	*vio0
591	Boot 0	Bus	*vio0
595	Boot 0	Bus	*vio5
596	Boot 1	Bus	*vio5

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

VIO Server Configuration:

VLAN ID	Adapter Type	Adapter Speed	VIO Server
500	Boot	Gigabit	*vio0
600	Standby	Gigabit	*vio0
750	Backup	10/100	*vio0
850	Management	10/100	*vio0
990	Intra-frame	Bus	*vio0
991	Intra-frame	Bus	*vio0
505	Boot	Gigabit	*vio5
605	Standby	Gigabit	*vio5
755	Backup	10/100	*vio5
855	Management	10/100	*vio5
995	Intra-frame	Bus	*vio5
996	Intra-frame	Bus	*vio5
