Whether 8GEF WSIC interface cards are Layer 2 or Layer 3 ones

7

The 8GEF WSIC interface card provides eight Gigabit SFP interfaces. SFP optical transceivers must be installed on the SFP interfaces for optical fiber connection. The optical interfaces provided by the 8GEF interface card support Layer 2/Layer 3 switchover and work in Layer 3 by default.
Perform as follows for switchover:
[Layer 3 to Layer 2] In the interface view, run the portswitch command to switch from Layer 3 mode to Layer 2 mode. Before switchover, clear all Layer 3 service configurations of the interface.
[Layer 2 to Layer 3] In the interface view, run the undo portswitch command to switch to Layer 3 mode. Before switchover, clear all configurations, excluding default ones, of the interface.
