Complete the following steps to configure a connection set:
Log into NetCloud Manager.
Select in the left-side navigation panel.
Select a router from the Routers page. Alternatively, to make configuration changes to a group, navigate to the Groups page and select a group.
Select and then .
Navigate to > .
Under WAN Management, select Smart WAN Selection.
Select Enable Smart WAN Selection. This option allows configuration of specific criteria thresholds that will be used to determine which interface should be connected. Smart WAN Selection enables greater control to dynamically determine which of the available WAN interfaces is connected and when/how the router should switch to an alternate interface. WAN selection is based on configurable selection criteria.
Note
Enabling Smart WAN Selection will override the existing failback settings.
Configure the following criteria if necessary:
Mode
Periodic – Recheck criteria periodically at the configured refresh interval and select the highest priority interface as determined by the current Resolution setting.
Acceptable – Continue using the currently connected interface as long as the interface's status continues to fall within the bounds of the configured criteria.
Refresh – The time interval the router will wait before reevaluating the enabled criteria to determine interface priority.
Resolution – This option determines which interface is selected when more than one interface meets all enabled criteria.
Manual – Use the priority order from the Connection Manager WAN Interface Profile and Priority list to prioritize the interfaces that meet all of the enabled selection criteria.
Best Fit – Prioritize all interfaces that meet the enabled selection criteria by the amount that each interface exceeds the criteria threshold of the highest priority criteria. If there is a tie, the second highest priority criteria is considered, and so on. Note that criteria priority can be adjusted by dragging and dropping criteria up or down.
Under Selection Criteria, choose the criteria for when Smart WAN Selection is applied. Selection Criteria are the conditions that will be evaluated when determining which interfaces are preferred. Interfaces that exceed all enabled criteria are prioritized above those that do not. Enable only the criteria that should be used in interface evaluation and configure appropriate criteria thresholds.
Note
The order of the criteria can be adjusted by dragging and dropping the rows up or down. This ordering matters only when Resolution is set to Best Fit and multiple criteria are enabled. When that occurs, the interfaces that meet all enabled criteria will be prioritized by the amount that each interface exceeds the threshold of the highest ordered and enabled criteria. If there is a tie, then the second highest criteria resolves the tie, and so on.
Signal Strength – Strength is a calculated percentage based on values read from the modem (Ethernet WAN connections will always report 100% strength). Set the minimum allowable signal strength. As strength drops below 50%, connections will become increasingly unreliable. The default is 50%.
Data Usage – The current percentage of the configured monthly, weekly, or daily usage cap is used to determine whether an interface passes this criteria. Data usage is configured in the WAN Interface Profile table on this page. If no data caps are set for an interface, the criteria will always pass (for example, the usage remaining will be 100%).
Latency – Set the maximum allowable latency period. Latency is the average round-trip time to send data from the router to the configured ping target and receive a response. The default is 1000 ms.
Jitter – Set the maximum allowable jitter. Jitter refers to the variation in latency on data sent between the router and the configured ping target. The default is 500 ms.
Note
Ping Target – The ping utility (ICMP Echo Request/Response) is used when measuring the latency and jitter criteria. The Ping Target should be set to an IP address or host name that is appropriate for your data usage (for example, a typical connection destination). The default is 8.8.8.8 (Google public DNS server).
Select .
Select Connection Sets.
Note
The number of supported sets may vary by platform.
From the Connection Set drop-down menu, select .
From the Load Balance drop-down menu, select . A Connection Set may optionally be load balanced to distribute traffic among the set members.
From the Load Balancing Algorithm drop-down menu, select an algorithm. The following load-balancing algorithms are available:
Round-Robin – Evenly distribute each session to the available WAN connections.
Rate – Distribute load based on the current upload and download rates. A WAN device's upload and download bandwidth values can be set in the Connection Manager page.
Spillover – The default algorithm. Load is always given to devices with the most available bandwidth. The estimated bandwidth rate is based on a combination of the upload and download configuration values and the observed capabilities of the device.
Data Usage – This mode works in concert with the Data Usage feature. The endpoint will make best effort to keep data usage between interfaces at a similar percentage of the assigned data cap in the Data Usage rule for each interface, rather than distributing sessions based solely on bandwidth. For proper function, you need to create data usage rules for each WAN device you will be load balancing. Make certain to select the Use with Load Balancing checkbox in the NCOS: How to Configure Data Usage Rules on an Ericsson Cradlepoint Router rule editor.
Note
All connection set members are used to increase data throughput when load balancing is enabled for a connection set. Adding a WAN interface to an active connection set automatically connects the WAN interface and adds it to the pool of WAN interfaces available for data transfer use. Interfaces configured with different IP modes (such as IPv4-only and IPv4+IPv6) are not load balanced. For dual-SIM devices, only one interface can connect at a time. If the SIMs are members of the same connection set, then either SIM1 or SIM2 connects, but not both SIMs.
