Ethernet Interfaces Feature Guide for Routing Devices
The CCC-DOWN flag is associated with a circuit cross-connect (CCC) connection, Layer
2 circuit, and Layer 2 VPN, which send the CCC-DOWN status to the kernel. The
CCC-DOWN flag indicates that the CCC is down. The CCC-DOWN status is sent to the
kernel when the CCC connection, Layer 2 circuit, or Layer 2 VPN is down. This in turn,
brings down the CE-facing PE interface associated with the CCC connection, Layer 2
circuit, or Layer 2 VPN.
When the CCC-DOWN flag is signaled to the IEEE 802.3ah protocol, the system takes
the action defined in the
action
about Layer 2 circuits, see the Junos OS Layer 2 Circuits Feature Guide, Junos OS VPNs
Configuration Guide.
