Switch Security 6 - 67
3. Refer to the values displayed within the IKE Policies tab to determine if an existing policy requires revision, removal or
a new policy requires creation.
Sequence Number Displays the sequence number for the IKE policy. The available range is from 1 to 10,000, with 1
being the highest priority value.
Encryption Displays the encryption method protecting 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.
Hash Value Displays the hash algorithm used to ensure data integrity. The hash value validates a packet
comes from its intended destination, 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.
Authentication
Type Displays 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.
SA Lifetime Displays an integer for the SA lifetime. With longer lifetimes, security defines future IPSec
security associations quickly. Encryption strength is great enough to ensure security without using
fast rekey times. Motorola Solutions recommends using the default value.
DH Group Displays the Diffie-Hellman (DH) group identifier. IPSec peers use the defined value to derive a
shared secret without transmitting it to one another.
