Configuring Interfaces For Layer 2 Mode - Dell Force10 Z9000 Configuration Manual

Configuring Interfaces for Layer 2 Mode

All interfaces on all switches that will participate in Spanning Tree must be in Layer 2 mode and enabled.
Figure 44-1. Example of Configuring Interfaces for Layer 2 Mode
R1(conf)# int range gi 1/1 - 4
R1(conf-if-gi-1/1-4)# switchport

To configure the interfaces for Layer 2 and then enable them:
Step Task
1 If the interface has been assigned an IP address,
remove it.
2 Place the interface in Layer 2 mode.
3 Enable the interface.
Verify that an interface is in Layer 2 mode and enabled using the
mode.
