When an interface is grouped in an interface set, the logical interface column is
modified, and interface set appears below the interface in the column. The interface
superset appears below the interface set.
Although interface sets enable you to configure more types of scheduler nodes, the
number of node and queue resources supported in the current scheduler hierarchy
are the same.
Interface Set Parents and Types
When configuring an interface set, you must assign a parent and the types of member
interfaces allowed in the set.
The parent of an interface set is an interface superset. The parent of the interface
superset can be any type of interface over which IP can be configured, including
ATM VP, Gigabit Ethernet, or 802.3ad LAG.
The parent of the interface superset controls the type of member interfaces you can
have in an interface set. Currently, member interface types include VLAN, ATM-VC,
and IP. For example, a interface superset with a Gigabit Ethernet or LAG parent
interface can only be the parent of interface set that contains VLAN and IP member
interfaces. In addition, all members of the interface set must have the same port.
Sample Interface Columns and Scheduler Hierarchies
Figure 57 on page 210 shows a sample interface column using interface sets and
interface supersets for VLANs.
