16.1 Automatic Software Update
The VSAT may be configured for receiving software updates from the SatLink Hub automatically.
Whenever the software upgrade application at the SatLink Hub transmits a new software image, the
software upgrade routine in the VSAT will start receiving the software image given that the new software
image has a newer revision than the current software. When the software download is completed
successfully, the VSAT will restart automatically in order to activate the new software version.
To automatically receive software upgrades, the VSAT must be configured with the PID, the multicast IP
address, and the UDP port allocated by the system operator for multicast software upgrade, with software
upgrade via multicast enabled, and with the VSAT receiver locked on the Forward Link. Issue the CLI
command sw show to examine the automatic software upgrade configuration:
#
sw show
SW versions:
Boot : 9.0.1.7
Current : 13.0.2.65
Backup : 13.0.2.61
Manual SW upgrade settings:
TFTP server IP addr : 10.10.1.1
File name : new.tgz
Automatic SW upgrade settings:
Activated : Yes
PID : 1022
IP address : 224.0.1.59
Port No. : 2001
Licenses for SW options:
NAT
GRE
PEP-TCP
QOS-4
PEP-HTTP
VLAN
Users with privilege level 2 may activate and deactivate the automatic software upgrade routine, and
change the PID, IP address, and UDP port number where the software is received by using the CLI
command sw mcast.
Example:
# sw mcast 1 511 224.0.1.59 2001
#
The above configuration will enable automatic reception of software upgrades on PID 511, IP address
224.0.1.59 and UDP port number 2001.
