70 EqualLogic Configuration Guide | Version 15.2 | August 2014
All devices in the iSCSI data path must have the same VLAN ID configured on the respective ports
participating in the iSCSI network to ensure proper functioning. These devices include the server iSCSI
NIC/CNA ports, EqualLogic arrays, and all switches on the iSCSI SAN.
Note: The VLAN ID for iSCSI can be set in the EqualLogic Group Manager interface or the storage array
CLI. When DCB is enabled on the switch, it is necessary to configure a non-default VLAN on the array,
switch, and all host ports that are part of the EqualLogic SAN. VLAN IDs 0 and 1 are not recommended,
because these may be the default or reserved VLAN for some switches, and as such, may forward frames
untagged (e.g. no VLAN tagging). VLAN tagging is required to fully support DCB.

and/or disabled across all devices, and to assist with identifying and resolving basic DCB configuration
issues in the EqualLogic SAN, see the following white paper: EqualLogic DCB Configuration Best Practices
