Technology Description
Please see Part 1: Cisco VNEs in this guide for information about which devices support the various technologies.
Local Switching
Local switching allows switching of Layer 2 data between two attachment circuits on the same device. Local switching operates in several modes and technologies.
In local switching (also known as hairpin connection), frames from one attachment circuit are switched to another attachment circuit on the same router. The attachment interfaces can be on the same line card or on different cards. During this type of switching, no address information is used at all. The local switching act as a kind of tube between the two interfaces.
Note Cisco ANA version 3.6 SP4 and later provides support for local switching only in Ethernet and VLAN modes on CRS-1 devices running IOS-XR software.
Information Model Objects (IMOs)
This section describes the following IMOs:
•Local Switching Entity
•Local Switching Entry
Local Switching Entity
The Local Switching Entity is the container for Local Switching Entry objects.
