TLS (Transport
Layer Security)
The TLS protocol provides communications privacy over the Internet. The protocol
allows client/server applications to communicate in a way that is designed to prevent
eavesdropping, tampering, or message forgery.
Traceroute
A utility used to identify the route used for station-to-station connectivity across the
network.
Trap
If a trap is defined in the MIB, a trap message is sent from the SNMP agent to the
SNMP manager when the trap is triggered. A trap can for example define a hardware
failure in a monitored device.
URI (Uniform
Resource
Identifier)
The addressing technology from which URLs are created. Technically, URLs such
as HTTP:// and FTP:// are specific subsets of URIs, although the term URL is mostly
heard.
VIP (Virtual Server
IP) Address
An IP address that the switch owns and uses to load balance particular service
requests (like HTTP) to other servers.
Virtual Router
A shared address between two devices utilizing VRRP, as defined in RFC 2338.
One virtual router is associated with an IP interface defined on the Application
Switch. All IP interfaces on an Application Switch must be in a VLAN. If there is more
than one VLAN defined on the Application Switch, then the VRRP broadcast will
only be sent out on the VLAN to which the associated IP interface has been
added.
Virtual SSL Server
A virtual SSL server handles a specific service on the VPN Gateway, such as
HTTPS, SMTPS, IMAPS, or POP3S. You can create an unlimited number of virtual
SSL servers per AVG cluster, and each virtual SSL server is mapped to a virtual
server on the Application Switch. To authenticate itself towards clients making
requests for the specified service, the virtual SSL server is configured to use a digital
certificate.
VLAN (Virtual
Local Area
Network)
VLANs are commonly used to split up groups of network users into manageable
broadcast domains, to create logical segmentation of workgroups, and to enforce
security policies among logical segments. Up to 246 VLANs are supported on an
Application Switch running Web OS.
VRRP (Virtual
Router
Redundancy
Protocol)
A protocol similar to Cisco's proprietary HSRP address-sharing protocol. The reason
for both of these protocols is to ensure devices have a next hop or default gateway
that is always available. For example, two or more devices sharing an IP interface
are either advertising or listening for advertisements. These advertisements are sent
through a broadcast message to address 224.0.0.18.
With VRRP, one switch is considered the master and the other is the backup. The
master is always advertising through the broadcasts. The backup switch is always
listening for the broadcasts. Should the master stop advertising, the backup will take
over ownership of the VRRP IP and MAC addresses as defined by the specification.
The switch announces this change in ownership to the devices around it by way of
a gratuitous ARP and advertisements. If the backup switch didn't do the gratuitous
