Stacking

An Aggregator auto-configures to operate in standalone mode. To use an Aggregator in a stack, you must

manually configure it using the CLI to operate in stacking mode.

Stacking is supported on the FN410S and FN410T Aggregators with ports 9 and 10 as the stack ports. The

Aggregator supports both ring and daisy-chain topology and stacking of the same type. FN 410S and FN 410T

Aggregators support two-unit in-chassis stacking and up to six units stacking across the chassis.

In Stack mode, the lower two external Ethernet ports (ports 9 and 10) operate as stack links. In Programmable

MUX (PMUX) mode, you can configure any of the external Ethernet ports to operate as stack links.

Stacking provides a single point of management for high availability and higher throughput. To configure a

stack, you must use the CLI.

Configuring a Switch Stack

To configure and bring up a switch stack, follow these steps:

1 Connect the ports on the base module of two Aggregators using 10G direct attach or SFP+ fibre cables.

2 Configure each Aggregator to operate in stacking mode.

3 Reload each Aggregator, one after the other in quick succession.
