Core issue
This issue occurs due to the presence of Cisco bug ID CSCdw42380.
When a LAN-to-LAN tunnel on the VPN concentrator is created to any device through the private interface (under Monitoring Sessions or under Administer Sessions), it appears under the Management Sessions as a Virtual Cluster Agent (VCA)/IPSec rather than as a LAN-to-LAN tunnel.
Note: This issue does not interrupt the traffic.
