Configuring Stacking Port Operation with the VIM3-40G4X Option Card

Configure port partitions and select between the native and alternate stack ports. When the VIM3-40G4X option card is installed, you can use the following ports for stacking:
  • The native stacking ports on the VIM3-40G4X option card, which can be configured for an 80 Gbps, 160 Gbps, or 320 Gbps data rate. These ports can also be partitioned to operate as one 40 Gbps data port or four 10 Gbps data ports.

  • The alternate stacking ports, which are defined in the following table.

After a configuration change, you must restart the switch to use the stacking ports.
