6.7.3 Viewing SA Statistics

A security association (SA) is a description of how two peers employ a security to interoperate securely. IKE
requires SAs to identify connection attributes. IKE can negotiate and establish its own SA. An IKE SA is used
by IKE only, and is bi-directional.
To view SA statistics:
1. Select Security
Define the priority for the IKE policy. The available range is from 1 to 65,543, with
1 being the highest priority value.
Set the encryption method used to protect the data transmitted between peers.
Options include:
• DES 56-bit DES-CBC. The default value.
• 3DES - 168-bit Triple DES.
• AES - 128-bit AES.
• AES 192 - 192-bit AES.
• AES 256 - 256-bit AES.
Define the hash algorithm used to ensure data integrity. The hash value validates
a packet comes from its intended source and has not been modified in transit.
Options include:
• SHA - The default value.
• MD5 - MD5 has a smaller digest and is somewhat faster than SHA-1.
Set the authentication scheme used to validate the identity of each peer. Pre-
shared keys do not scale accurately with a growing network but are easier to
maintain in a small network. Options include:
• Pre-shared Key - Uses pre-shared keys.
• RSA Signature - Uses a digital certificate with keys generated by the RSA
signatures algorithm.
Define an integer for the SA lifetime. The default is 60 seconds. With longer
lifetimes, security defines future IPSec security associations quickly. Encryption
strength is great enough to ensure security without using fast rekey times.
Motorola recommends using the default value.
Set the Diffie-Hellman group identifier. IPSec peers use the defined value to derive
a shared secret without transmitting it to one another.
Status field for the state of the requests made from applet. This field displays error
