VLAN
VLAN (Virtual Local Area Network) is a logical grouping mechanism implemented on
switch device using software rather than a hardware solution. VLANs are collections of
switching ports that comprise a single broadcast domain. It allows network traffic to flow
more efficiently within these logical subgroups. Please consult your network switch user
manual for VLAN setting instructions. Most of the work is done at the switch part. All you
need to do is to make sure that your iSCSI port’s VLAN ID matches that of switch port.
VLAN ID is a 12-bit number.
PCP(Priority Code Point) is a 3-bit number and reserved for QoS.
VLAN IDs range from 2 to 4094 with 0, 1, and 4095 reserved for special purposes (they
are different from switches to switches.). Our PCP definition comply with IEEE 802.1p
protocol, ranging from 0 to 7, with 0 as the default value. In normal cases, you don’t need
to set PCP value. Using the default setting will do just fine.
Assign VLAN ID to iSCSI ports
1.
Go to “iSCSI Configuration”, select “NIC” tab.
2.
Click on “OP” button of which port you prefer. Select “Set VLAN ID”.
Figure 5.12.1
3.
Put in the same VLAN ID of the corresponding switch port that the iSCSI port is
plugged in. And click “Ok”.
