Group Ports

Logical Interface

Logical interface is a grouping mechanism of physical Interfaces configured on Link Load Balancer including LAN & WAN. Users can create, modify, delete interface groups, and set desired monitor types for each interface group.

High availability (HA) is the ability of a system to operate continuously without failure for a designated period of time. HA works to ensure a system meets an agreed-upon operational performance level. High availability (HA) is usually required in a system where there is high demand for a little downtime. Haltdos LLB has the option of a logical grouping of physical interfaces for a highly available WAN connectivity structure.

How to Use:​

  1. Go to Apps > LLB > Group Ports.

  2. Click on Add Group Ports

  3. Configure your settings.

  4. Click Save.

Description:​

Name​

It allows the user to add a Group Name.

    Accepted values: String

    Default: Blank

LB Algorithm​

This option species the WAN Load Balancing algorithm used to balance the load between multiple WAN links. Users can select the WAN algorithm from the drop-down menu. In Haltdos LLB users get many WAN algorithms which are mentioned below.

    Accepted values: Round Robin / Source IP / Bandwidth / Sessions

    Default: 600

a) Round Robin: The administrator assigns a weight to each WAN connection based on criteria of their choosing for their traffic-handling capability. If the WAN 1 connection is twice as better for data communication as WAN 2. then WAN 1 is to be given a double weight value in comparison to WAN 2.

b) Source IP: Source IP hash load balancing algorithm that combines source and destination IP addresses of the users and websites to generate a unique hash key. The key is used to allocate the client to a particular server. As the key can be regenerated if the session is broken, the client request is directed to the same server it was using previously.

c) Bandwidth: In the least bandwidth method Users are selected based on the WAN Link's bandwidth consumption i.e WAN connection that consumes the high bandwidth is selected (measured in Mbps).

d) Sessions: Session load balancing is a dynamic load balancing algorithm where user requests are distributed to the WAN connection with the least number of active connections at the time the user's request is received.

Criteria​

It specifies the other network-based conditions for load balancing. Users can select from many options to figure out any network fluctuation in connectivity. Users can set their packet drop, jitter, latency, etc.

    Accepted values: Select Criteria

    Default: Blank

Failover Threshold​

Specify the failover threshold in percentage of (active / total) primary servers for switching to backup servers.

    Accepted values: Integer

    Default: 100

Monitor Type​

It allows the user to select the rule to monitor the terrific. This monitor rule can be added from Monitors.

    Accepted values: Select Monitor Type

    Default: NOne

Member​

This option will show a list of all WAN links with their names.

    Accepted values: Select Member

    Default: Blank

Weight​

This option allows the user to set the weight value for an interface. This is a static numerical weighting. Interface with higher ratings gets more requests sent to them.

    Accepted values: Integer

    Default: 100

Backup​

This field allows the user to enable or disable the backup. By default, It's set on disable.

    Accepted values: Enable / Disable

    Default: Disable
