Use Case Study: Using Active System For VMware Cluster Environment Configuration
7
In a LAN-only configuration, the LAN distribution switches have only four types of ports:
Out-of-band management
Stacking ports
Downlinks to the I/O aggregator in the M1000e chassis
Uplinks to the routed network
Downlinks to the I/O aggregators must be configured as LACP-enabled LAGs. LACP must also be enabled
on the LAN distribution switches to allow auto-configuration of downstream I/O aggregators and to tag
network VLANs on the LAGs, since they will be used to configure VLANs on the downstream switch.
This example shows multiple ports of the Force10 S4810 configured to connect to the I/O Aggregator.
Each port channel is also configured with the appropriate VLANs to carry the environment’s Ethernet
traffic. These ports drive auto-configuration of VLANs on the I/O aggregator LAGs.
