Configuring IP Security Services

A-4

304111-A Rev 00

Parameter:

Security Parameter Index

Path: Configuration Manager > Protocols > IP > IP Security > Security Associations

(SAs)

Default:

256

Options:

256 through 65535

Function:

The security parameter index (SPI) is an arbitrary 32-bit value that, when

combined with the destination IP address and the numeric value of the security

protocol being used (ESP), identifies the security association (SA) for the data

packet.

Instructions:

Enter a value from 256 through 65535.

MIB Object ID:

Parameter:

Cipher Algorithm

Path: Configuration Manager > Protocols > IP > IP Security > Security Associations

(SAs)

Default:

DES CBC

Options:

None

DES CBC

Function:

Identifies the cipher algorithm for this security association (SA).

Instructions:

To implement the cipher (or confidential/encrypted) level of security, select the

Data Encryption Standard (DES) algorithm. If you select None, this level of

security will not be applied to data packets processed according to this security

association (SA); that is, the data packets will not be encrypted.

MIB Object ID:

1.3.6.1.4.1.18.3.5.3.26.5.1.6

Parameter:

Cipher Key Length

Path: Configuration Manager > Protocols > IP > IP Security > Security Associations

(SAs)

Default:

DES56

Options:

DES40

DES56

Function:

Identifies the cipher key length (strength) for this security association (SA).

Instructions:

Select a cipher key length of either 40 or 56 bits. The longer key length

(strength) provides greater security.

MIB Object ID:

1.3.6.1.4.1.18.3.5.3.26.5.1.8
