CX31x stacking configuration


The CX31x supports stacking.
The stacking function stacks a group of switches to form a single logical stack unit to increase the bandwidth and improve the reliability.
The stacked switches in the group take the following roles:
? Master switch: One master switch manages the entire stacking system. It allocates stacking member numbers, collects stacking topology information, and sends the topology information to all stacking members in the system.
? Standby switch: Only one standby switch is operating in the entire stacking system. When the master switch fails, the standby switch takes over the services and functions as the master switch.
? Slave switch: Any switch except the master switch in a stack. The standby switch is also a slave switch. When detecting neighbor loss, a slave switch sends a topology change packet to the master switch.

The stacking function for the CX31x applies to the scenarios that require higher port density and forwarding capacity, network capacity expansion, and the ease of user management. For details about the CX31x stacking configuration, see the following documents.

Meaning of the CX31x converged switching
Converged switching (which is not strictly defined) indicates the switching that adopts DCB Ethernet switches that support FCoE traffic and E9000 CX310, CX311, and CX312 converged switch modules. Converged networking (which is not strictly defined) indicates the Ethernet networking in the server field that bears the traditional Ethernet data traffic and FCoE traffic. This Ethernet networking must be based on the DCB feature.
