Deployment Guide

Revert from DCB to non-DCB configuration (optional)

4.4 Revert to default VLAN ID on switch and arrays
Once DCB is disabled on the switch, the SC Series arrays will no longer use the VLAN ID that was configured
when DCB was enabled. The arrays will revert to the default or native VLAN. Therefore, a valid VLAN must
be configured for all host servers, switches, and SC Series array members. A valid VLAN can use the default
or native VLAN ID (typically 0 or 1), or a specific VLAN can be configured (for example, VLAN 100). If a non-
default VLAN is configured, any ports connected to the arrays must be configured as untagged.
The steps in section 4.3 revert the switch ports to default native vlan 1. Use the following command to remove
VLANs other than vlan 1 from the switch configuration.
OS10(config)# no interface vlan <vlan-id>
