High Availability High Availability (HA) is supported through automatic
fault-tolerant fail-over to a secondary Clavister Security
Gateway device. The two devices act together as a cluster,
with one being active while the other is passive but
constantly mirroring the state of the active unit.
This feature is described in more detail in Chapter 11, High
Availability.
Virtualization cOS Core supports virtualization using one of two
techniques:
• Using separate cOS Core routing tables, as mentioned
above under IP routing, it is possible to create separate
virtual routers. Although a single version of cOS Core is
being run it is possible to create separate sets of IP rules
and other policies.
See Section 4.5, “Virtual Routing” for more information
about this topic.
• Using VMware it is possible to have multiple,
independent versions of cOS Core running on a single
computer. This option is not available on Clavister
hardware
but runs, instead, as a software-only
installation on non-Clavister hardware that has VMware
installed.
Installation with VMware is described in the separate
Clavister V Series Getting Started Guide.
IPv6 IPv6 addresses are supported on interfaces and within rule
sets. This feature is not enabled by default and must be
explicitly enables on an Ethernet interface.
More information about this topic can be found in
Section 3.2, “IPv6 Support”.
In addition to the list above, cOS Core includes a number of other features such as RADIUS
Accounting, DHCP services, protection against Denial-of-Service (DoS) attacks, support for PPPoE,
GRE, dynamic DNS services and much more.
cOS Core Documentation
Reading through the available documentation carefully will ensure getting the most out of the
cOS Core product. In addition to this document, the reader should also be aware of the
companion reference guides:
• Separate Getting Started Guides detail how to set up a new installation of cOS Core.
• The CLI Reference Guide which details all cOS Core CLI commands.
• The cOS Core Log Reference Guide which details all cOS Core log event messages.
Together, these documents form the essential reference material for cOS Core operation.
