Configuring Packet Load Balancing over One to Many Links

When  VirtualWire  is deployed as legacy packet broker, moving packets from production to an analyzer tool, it requires load balancing feature because you can monitor 10Gb links with 1Gb tools.

Netvisor One load balances the traffic by distributing the traffic load to different tool ports or appliances in order to scale the monitoring. This also provides redundancy in the monitoring technology.

When a member port goes down, traffic on the port is switched to remaining member ports and evenly distributed.

To configure load balancing, use the following steps:

1) First configure a trunk on the desired ports. In this case, ports 15 and 16 are configured as a trunk:

CLI (network-admin@Leaf1) > trunk-create name lb_trunk ports 15,16

Created trunk lb_trunk, id 128

2) Create the port association on the switch:

CLI (network-admin@Leaf1) > port-association-create name pa1 master-ports 1 slave-ports 128 virtual-wire bidir

3) Display the configuration:

CLI (network-admin@Leaf1) > port-association-show

switch  name master-ports slave-ports policy      virtual-wire bidir

------- ---- ------------ ----------- ----------- ------------ -----

leaf1   pa1    1            128       all-masters   true        true

CLI (network-admin@Leaf1) > port-show port 1,16

switch  port vnet hostname status config    trunk

------- ---- ---- -------- ------ --------- --------

leaf1    16                 trunk  10g,jumbo lb_trunk
