Interface Naming Conventions
Portgroup Interfaces
This logical interface represents the aggregation of multiple packet streams from slow speed interfaces.
For example, this interface is used on the Cisco ONS 15530 optical switches, where the switching
granularity is only on the level of a 2.5-Gbps aggregate packet stream resulting from multiple slow speed
interfaces such as esconphy.
The portgroup interfaces are located on the ESCON multiplexing line cards. The portgroup interface
connects the esconphy interfaces on the front panel to the switch fabrics. A logical interface representing
the aggregation of multiple ESCON client signals.
The naming convention for the portgroup interfaces on the ESCON multiplexing line card is as follows:
portgroup slot/subcard/port
Each ESCON multiplexing line card has only one portgroup interface.
10-Gbps ITU Trunk Card Interfaces
The 10-Gbps ITU trunk cards have four types of interfaces:
• Ethernetdcc interfaces
• Wavethernetphy interfaces
• Wavethernetphy subinterfaces
• Wavepatch interfaces
Figure 2-2 shows the interfaces for the splitter 10-Gbps ITU trunk card. Figure 2-3 shows the interfaces
for the nonsplitter 10-Gbps ITU trunk card.
