Configuring a Switch Stack
To configure and bring up a switch stack, follow these steps:
1 Connect the 40GbE ports on the base module of two Aggregators using 40G direct attach or QSFP fibre cables.
2 Configure each Aggregator to operate in stacking mode.
3 Reload each Aggregator, one after the other in quick succession.
Stacking Prerequisites
Before you cable and configure a stack of MXL 10/40GbE switches, review the following prerequisites.
• All Aggregators in the stack must be powered up with the initial or startup configuration before you attach the cables.
• All stacked Aggregators must run the same Dell Networking OS version. The minimum Dell networking OS version required is 8.3.17.0.
To check the version that a switch is running, use the show version command. To download a Dell Networking OS version, go to
http://support.dell.com.
• Stacking is supported only with other Aggregators. A maximum of six Aggregators are supported in a single stack. You cannot stack
the Aggregator with MXL 10/40GbE Switches or another type of switch.
• A maximum of four stack groups (40GbE ports) is supported on a stacked Aggregator.
• Interconnect the stack units by following the instructions in Cabling Stacked Switches.
• You cannot stack a Standalone IOA and a PMUX.
