Nasuni Edge Appliance Initial Configuration Guide 8.3 26
Configuring the Nasuni Edge Appliance Network Settings
Network Settings
The next step is to configure network parameters. This section gives general information about traffic
groups, and specific procedures for configuring the network settings.
Note: IPv6 is not supported.
Traffic Groups
Three default traffic groups are available, but you can change the purpose and the name of each traffic
group:
• General: All traffic is in the General traffic group, unless explicitly assigned to a different traffic
group. Systems with only one network interface card (NIC) always use the General traffic group.
This traffic group is not for any specific purpose.
• Management: The Management traffic group limits access to the assigned interfaces of the
Nasuni Edge Appliance to administrative access only.
• External: The External traffic group designates a set of interfaces that carry only Web Access
traffic and Mobile Access traffic.
Note: You use the Firewall configuration page to configure what kind of traffic the Nasuni Edge
Appliance accepts on each traffic group.
You cannot combine traffic from two or more traffic groups together.
Note: If a proxy is defined such that it is on one of the networks local to the Nasuni Edge
Appliance, this local proxy is used for cloud traffic, Remote Support traffic, and Nasuni API
traffic. Traffic flows on whichever interface can reach the local proxy.
Bonding. If you assign more than one device to the same traffic group, the assigned devices are
“bonded” for that traffic group. A bonded interface is a virtual network interface that runs on two or
more physical interfaces. The Nasuni Edge Appliance uses bonding mode 5 (balance-tlb) for high-
availability (HA) networking with a performance enhancement when sending packets. This has no
requirement from the switches. This bonding mode can be changed by Nasuni Support, if necessary.
Bonding also provides failover benefits. This bonding mode monitors the state of the network interface
cards (NICs) that are in the bond: if the active device fails, it switches to a different active device. In
addition, when transmitting a packet, the system determines (using an internal metric) which device in
the bond is least busy, and transmits the packet using that device. When the host sends a packet to the
Nasuni Edge Appliance, the packet always goes to the active device.
Network switch ports to which bonded Nasuni Edge Appliance ports are attached must be configured
as switch port access with trunk access disabled. Any switch port where a bonded Nasuni Edge
Appliance port is attached should also not be bridged with any other Nasuni Edge Appliance port.
Note: Nasuni supports either Balance-TLB or the Link Aggregation Control Protocol (LACP) to
bond several physical ports together to form a single logical channel. While Balance-TLB is
the default, LACP allows a network device to negotiate an automatic bundling of links. If
your switch supports LACP, Nasuni recommends using LACP as a best practice. To
enable LACP, contact Nasuni Technical Support.
