Dell EMC PowerVault MD 34XX/38XX Series Storage Arrays Administrator's Guide

Use the advanced settings for the individual iSCSI host ports to specify the TCP frame size, the virtual LAN, and the network priority.

Setting

Description

Virtual LAN (VLAN)

A method of creating independent logical networks within a physical network. Several VLANs can exist within a network. VLAN 1 is the default VLAN.

NOTE: For more information about creating and configuring a VLAN with MD Support Manager, in the AMW, click the Support tab, then click View Online Help.

Ethernet Priority

The network priority can be set from lowest to highest. Although network managers must determine these mappings, the IEEE has made broad recommendations:

• 0—lowest priority—default
• (1–4)—ranges from “loss eligible” traffic to controlled-load applications, such as streaming multimedia and business-critical traffic
• (5–6)—delay-sensitive applications such as interactive video and voice
• 7—highest priority reserved for network-critical traffic

TCP Listening Port

The default Transmission Control Protocol (TCP) listening port is 3260.

Jumbo Frames

The maximum transmission units (MTUs). It can be set between 1501 and 9000 Bytes per frame. If the Jumbo Frames are disabled, the default MTU is 1500 Bytes per frame.
