OmniAccess 5510 USG - Release Notes
September 2010
TFTP Server/Client
TFTP (Trivial File Transfer Protocol) is a simplified version of FTP that allows for the transfer of
files to and from a device. The TFTP client/server package on OmniAccess 5510 USG allows the
system to act as either a TFTP client or server for downloading files. Currently, uploading of files to
the TFTP server running on OmniAccess 5510 USG is not supported.
DNS Client
The DNS Client functionality on OmniAccess 5510 USG allows for resolution of host names to IP
addresses, and vice-versa.
DHCP Client
DHCP is a protocol used to configure an IP device connected in a network. The configuration
parameters include IP address, DNS information, default route, and so on. DHCP uses client-server
architecture. DHCP client gets IP address for its broadcast interface and other essential network
configuration information (like DNS server, TFTP server) from the DHCP server.
DDNS Client
DDNS is a service that provides the capability for a network device to perform DDNS updates to
ensure that an IP host DNS name is correctly associated with its IP address. In general, WAN IP
address is dynamic, and it becomes very difficult to access the network device with WAN IP
whenever there is any change in the IP address. DDNS updates the WAN IP address in DNS server,
so, it facilitates to access device from WAN side by using the unique domain name.
TR-069 Client
TR-069 (or Technical Report 069) from the Broadband forum provides a bi-directional configuration
and provisioning mechanism between customer-premises equipment (CPE) and Auto Configuration
Servers (ACS) using SOAP/ HTTP. The CPE WAN Management Protocol (CWMP) is an
application-layer protocol that provides discovery, configuration, image management and diagnostics.
OmniAccess 5510 USG supports two modes of TR-069 configuration.
Manual mode - All the required parameters for ACS are to be configured manually using the
respective CLI commands.
Automatic mode in zero-touch mode (Auto-configuration - ACS Auto-Discovery and dynamic service
provisioning) - Auto-discovery feature enables TR-069 client to automatically discover URL of its
assigned ACS, user name and the password.
Secure Shell (SSH)
The Secure Shell feature provides a secure mechanism that allows you to log in to a remote system, to
execute commands on a remote device, and to move files from one device to another. Secure Shell
provides secure, encrypted communications even when your transmission is between two untrusted
hosts or over an unsecured network.
