Attribute definition for PrivNIC agent

The following table describes the user-modifiable attributes of the PrivNIC resource type

Required Attributes

Attribute

Dimension

Description

Device 

string -association 

Specifies the network interface device as shown by the "ifconfig" command and the "network-id" associated with the interface; for example: lan0=0. Network-ids of the interfaces connected to the same physical network must match. The interface with the lower network-id has the higher preference for failover. At least one interface device must be specified. Example: 

Device@galaxy = {lan0=0, lan1=1, lan2=2}

Device@nebula = {lan0=0, lan1=1, lan2=2}

Address  

string-scalar  

The numerical private IP address. For example: 

Address = "192.168.12.1"

NetMask  

string -association 

The numerical netmask for the private IP address. For example: 

Address = "255.255.255.0"

Description

DeviceTag 

string -association 

Associates an LLT device "tag" with device via the network-id. If an LLT device tag (as specified in the /etc/llttab file) differs from the name of the network interface as shown in "ifconfig," then DeviceTag must be specified for that interface. 

For example: in the common case, /etc/llttab contains: 

link lan0 /dev/lan:0 - ether - -

link lan1 /dev/lan:1 - ether - -

link-lowpri lan0 /dev/lan:0 - ether - -

In the above case, DeviceTag does not need to be specified. However, if /etc/llttab contains: 

link link1 /dev/lan:0 - ether - -

link link2 /dev/lan:1 - ether - -

link-lowpri spare /dev/lan:0 - ether - -

And,  

Device@galaxy = { lan=0, lan1=1, lan2=2 }

DeviceTag needs to be specified as: 

DeviceTag@galaxy = { spare=2 }

GabPort 

string-scalar  

A single lower-case letter specifying the name of the GAB port to be used for filtering. "o" is the default. NULL disables GAB port filtering.  

Example: GabPort = "b" 

UseVirtualIP 

integer-scalar 

The default is 0, which specifies that the agent use the physical interface for configuring the private IP address when possible. 

The value 1 specifies that the agent always use the virtual interface for configuring the private IP address. 

The value 2 (which includes the functionality of the value 1) specifies the agent should complain if the private IP address already exists on a physical interface. 

UseSystemList 

integer-scalar 

The value 1 specifies that the agent use the SystemList of the service group to filter the node list. The default is 0. 

ExcludeNode 

integer-vector 

List of nodes to be permanently excluded from calculation.
