Option Description
Df Bit
Df Bit indicates how the Don’t Fragment (DF) bit in the IP
header should be be handled in tunnel mode. You can
choose from the following dfbitcfg values:
If copy is set, the DF bit in the outer IP (tunnel) header is
copied from the inner IP header.
If set is set, the DF bit is always set to 1 in the tunnel IP
header. This should only be specified if the SA is a tunnel
mode SA.
If clear is set, the DF bit in the tunnel header will always be
reset.
Bundle Id
A unique identifier for each SA that forms part of a bundle. All
SA bundles associated with a policy should have different
bundleids. By default, the bundleid is 0, signifying that the SA
is not part of any bundle or is a single SA.
e.g. 0.
Bundle Order
The Bundle Order specifies the location of a particular SA in a
bundle. This is a mandatory parameter if bundleid is
specified. It can take positive integer values. The SA with the
lowest bundleorder value is applied first, followed by the
higher bundleorder value, irrespective of the direction of the
SA.
e.g. 0.
SPI
SPI specifies a unique value. If the SA is applicable to
inbound traffic (in), the SPI is assigned by the sender. If the
SA is applicable to outbound traffic (out), the SPI is assigned
by the receiver. This value must be greater than 255 and less
than 65536.
e.g. 300.
Self Ipv4Addr
The source gateway addresses for IPv4 packets. These are
only specified in tunnel mode.
Peer Ipv4Addr
The destination gateway addresses for IPv4 packets. These
are only specified in tunnel mode.
Addr Ver
IPv4 or IPv6. Only IPv4 is currently supported.
IPsec SA Stats for
SA
statistics about the number of inbound and outbound packets
that match a specific IPsec policy.
Aut Algo
Indicates the authentication algorithm used for IPsec
processing. Supported values are md5 and sha1.
e.g. md5
Enc Algo
Indicates the encryption algorithm used for IPsec processing.
It can only be specified if the IPsec protocol used is ESP.
Supported values are des and 3des.
e.g. 3des.
