3. To create a VLAN-enabled group from the grouped ports, check Create VLAN enabled
Group.
4. By default, the MTU size is 1500. To enlarge this size, select 4088 or 9000 from the MTU
Size drop-down list.
5. Under Select Ports to Group, click each Ethernet port you want to make a member of
this group.

To select adjacent ports, click the top one you want to select, then hold down the

group (see Figure 7-10).
While the standard MTU size (and default value) is 1500, you can select a
larger value if your iSCSI network can handle a larger frame size to see
whether it improves performance. Note, however, that selecting a higher
MTU value (known in the industry as “jumbo frames”) requires all network
equipment involved, such as switches, to be capable of and configured to
handle an MTU of at least 4088 or 9000, depending on your selection. Note
that the selection of 9000 is only available with xStack Storage systems that
have four or fewer data ports.
