Interface Groups

Based on your criteria, determine which Interface groups to create. Remember that interface groups are evaluated first (see Concepts for State Polling). Interface groups can reference node group membership, so you might end up configuring node groups before interface groups to implement your plan.

Preconfigured interface groups

NNMi has several useful interface groups already configured for you to use. These include:

• All interfaces with an IFType related to ISDN connections
• Interfaces for voice connections
• Interfaces for point-to-point communication
• Software loopback interfaces
• VLAN interfaces
• Interfaces participating in link aggregation protocols

Over time might add more default groups to simplify your configuration tasks. You can use existing groups, modify them, or create your own.

Interface groups have two types of qualifiers: node group membership for the hosting node and IFType or other attribute for the interface. You can choose to combine these as follows:

• All interfaces on nodes in a node group are grouped regardless of IFType; do not select any IFTypes or attributes (such as name, alias, description, speed, index, address, or other IFType attributes).
• All interfaces of certain IFTypes or set of attributes are grouped, regardless of the node on which they reside.
• Only interfaces of a certain IFType or attributes that reside on a particular group of nodes are grouped.
