Key Management 
Key – Key Type: there are two key types (manual key and auto key) 
available for the key exchange management.  
Manual Key: If manual key is selected, no key negotiation is needed. 
Encryption Key- This field specifies a key to encrypt and decrypt IP 
traffic. Authentication Key – This field specifies a key use to auth           
entication IP traffic. Inbound/outbound SPI (Security Parameter Index) 
– 
is carried on the ESP header. Each tunnel must have a unique 
inbound and outbound SPI, and no two tunnels share the same SPI. 
Notice that Inbound SPI must match the other router’s outbound SPI. 
AutoKey (IKE)- There are two types of operation modes can be used. 
Main mode accomplishes a phase one IKE exchange by establishing a 
secure channel. Aggressive Mode is another way of accomplishing a 
phase one exchange. It is faster and simpler than main mode, but does 
not provide identity protection for the negotiating nodes. 
Perfect Forward Secrecy (PFS) – If PFS is enable, IKE phase 2 
negotiation will generate a new key material for IP traffic encryption & 
authentication. Preshared Key – This field is to authenticate the remote 
IKE peer. Key Lifetime- This is specified the lifetime of the IKE 
generated Key. If the time expires or data is passed over this volumn, a 
new key will be renegotiated, By default, 0 is for no limit.
