IPSec tunnel interfaces are not modeled for CiscoASA device models.
TheCiscIPSecExtAp application model provides the intelligence for the creation of IPSec Tunnel interface models. Spectrum currently requires a device to provide data from the CISCO-IPSEC-MIB and CISCO-IPSEC-FLOW-MONITOR-MIB for the creation of the CiscIPSecExtAp application model creation. Cisco ASA devices do not provide data from the CISCO-IPSEC-MIB (the default attr is cipsIsakmpEnabled).
Cisco ASA devices do not provide data from the CISCO-IPSEC-MIB (the default attr is cipsIsakmpEnabled) therefore tunnel interfaces will not be modeled for Cisco ASA devices.
