www.dell.com | support.dell.com 204 | Stacking MAC Addressing All port interfaces in the stack use the MAC address of the management interface on the master switch. The MAC address of the chassis in which the master Aggregator is installed is used as the stack MAC address. The stack continues to use the master’s chassis MAC address even after a failover. The MAC address is not refreshed until the stack is reloaded and a different unit becomes the stack master. Stacking LAG When you use multiple links between stack units, FTOS automatically bundles them in a stacking link aggregation group (LAG) to provide aggregated throughput and redundancy. The stacking LAG is established automatically and transparently by FTOS (without user configuration) after peering is detected and behaves as follows: • The stacking LAG dynamically aggregates; it can lose link members or gain new links. • Shortest path selection inside the stack: if multiple paths exist between two units in the stack, the shortest path is used. Stacking VLANs When you configure an Aggregator to operate in stacking mode (Configuring and Bringing Up a Stack), VLANs are reconfigured as follows: • If an Aggregator port belonged to all 4094 VLANs in standalone mode (default), all VLAN membership is removed and the port is assigned only to default VLAN 1. You must configure additional VLAN membership as necessary. • If you had manually configured an Aggregator port to belong to one or more VLANs (non-default) in standalone mode, the VLAN configuration is retained in stacking mode only on the master switch. When you reconfigure an Aggregator from stacking to standalone mode: • Aggregator ports that you manually configured for VLAN membership in stacking mode retain their VLAN configuration in standalone mode. • To restore the default auto-VLAN mode of operation (in which all ports are members of all 4094 VLANs) on a port, enter the auto vlan command; for example: FTOS(conf)# interface tengigabitethernet 0/2 FTOS(conf-if-te-0/2)# auto vlan
Stacking Port Numbers By default, each Aggregator in Standalone mode is numbered stack-unit 0. Stack-unit numbers are assigned to member switches when the stack comes up. Figure 17-17 shows the numbers of the 40GbE stacking ports on an Aggregator. Figure 17-17. Stack Groups on an Aggregator Configuring a Switch Stack Stack Unit 0 / Port 37 Stack Unit 0 / Port 33 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 | 205
