Select SNTP Synchronization mode(s): This action enables/disables the STNP client in a
particular time synchronous access mode. There are three modes to choose from, and each
mode has enable and disable options:
Unicast mode:
• Enable - The mode uses a unicast server and the IP address or hostname in the SNTP
server association list is used to synchronize the client time with the server. The SNTP client
attempts to contact the specific server in the association in order to receive a timestamp
when the sntpclient sync command is issued.
• Disable - The unicast server is removed from the association list.
Broadcast mode:
• Enable - Allows the SNTP client to accept time synchronization broadcast packets from an
SNTP server located on the network, and update the local system time accordingly.
• Disable - Stops synchronization via broadcast mode.
Anycast Mode:
• Enable - The SNTP client sends time synchronized broadcast packets to the network and
subsequently expects a reply from a valid timeserver. The client then uses the first reply it
receives to establish a link for future sync operations in unicast mode. This server will then be
added to the server association list. The client ignores any later replies from servers after the
first one is received.
The enabled anycast mode takes precedence over any entries currently in the associations
list when the sntpclient sync command is issued. The entry will then be substituted for any
existing entry in the unicast association list.
• Disable - stops synchronization via anycast mode.

4. Security Associations Information: a security association (SA) provides security services
between IPsec peers for certain IP packets. SAs operate in a single direction; you would
usually create a pair of SAs for two-way traffic (inbound and outbound).

Policy Name Name of the policy
First SA Name Name of 1st security association
Protocol Each SA supports a single security protocol - AH or ESP. If
you want to use both protocols simultaneously, you need to
create a bundle of one or more SA pairs.
Mode The SA mode - tunnel or transport:
• in tunnel mode you must also specify the source and
destination addresses (either IPv4 or IPv6) of the security
gateways that form the IPsec peers. You can also optionally
configure how IPsec deals with fragmentation and reassembly
of packets.
• in transport mode, the IPsec policy referenced in the
command provides the necessary source and destination
address information.

This option is only relevant if applyipsec has been
selected. It is used to control the interpretation of
two tunnel mode SAs in an SA bundle as follows:
When two tunnel-mode SAs (SA1 and SA2) in a
bundle have the same local and peer end points and
complexsabundle is set to disable, then apart from
IPsec headers, only one new IP header is added on to
the original packet. For example, for an AH tunnel
- ESP tunnel SA bundle, the packet formed would
be as follows:
IP-AH-ESP-[IP_internal+Upper layer]
If complexsabundle is set to enable, the packet
formed would be as follows:
IP-AH-IP-ESP-[IP_internal+Upper layer]
When set to enable, this option specifies whether to
prefer the DYING SAs over MATURE SAs. When set to

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.
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.
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 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.
