IOMEGA STORCENTER IX12-300R ADVANCED NETWORK CONFIGURATION GUIDE VLAN CONFIGURATION VLAN is essentially a Layer 2 (Data Link Layer) construct, while an IP subnet is a Layer 3 (Network Layer) construct. In an environment employing VLAN, a many-to-many relationship can exist between VLANs and IP subnets. It is possible to have multiple subnets on one VLAN or have one subnet spread across multiple VLANs. The protocol most commonly used today in VLAN configuration is IEEE 802.1Q. Other proprietary p

IOMEGA STORCENTER IX12-300R ADVANCED NETWORK CONFIGURATION GUIDE NIC bonding can be configured in different modes. Some typical modes include: t NIC failover: this mode provides adapter fault tolerance through automatic failovers from an active NIC to a standby NIC in the case of switch port, cable, or NIC failure. No switch configuration is required for this mode. It works with any switch or hub. t Adaptive transmit load balancing (TLB): this mode provides transmit traffic load balancing and fa

IOMEGA STORCENTER IX12-300R ADVANCED NETWORK CONFIGURATION GUIDE Most Gigabit Ethernet switches and Gigabit NICs support Jumbo Frames, but all Fast Ethernet switches and Fast Ethernet NICs do not support Jumbo Frames. Normally IP networks require that all hosts in a subnet have an identical MTU. Therefore, when using Jumbo Frames, the best practice is to enable Jumbo Frames on all network interfaces connected to the same subnet. To reduce interoperability issues, NICs capable of Jumbo Frames req

IOMEGA STORCENTER IX12-300R ADVANCED NETWORK CONFIGURATION GUIDE CONFIGURATION PROCEDURE As illustrated collectively in the procedures below, when using all these advanced network capabilites together the following limitations apply on the StorCenter ix12-300r: t VLAN can be configured on individual physical NICs, but cannot be configured on bonded NICs. Each NIC can have up to four VLANs. t NIC bonding can add individual physical NICs that do not have VLAN configured and do not participate in a

IOMEGA STORCENTER IX12-300R ADVANCED NETWORK CONFIGURATION GUIDE 2. Click the button next to an interface to add a VLAN for the interface and enter the network settings for the VLAN. The existing network configuration of the interface does not need to be removed. Figure 2 Add a VLAN 3. Repeat step 2 to add more VLANs to the interface. The corresponding switch port must be tagged accordingly with the VLAN IDs. After this step, the NIC has five different working IP addresses assigned to it.
