Chapter 53 Configuring IPv4 for Gigabit Ethernet Interfaces VLANs Send documentation comments to [email protected] Use the VLAN ID as a subscription to the Gigabit Ethernet interface name to create the subinterface name (the /.). Configuring the VLAN Subinterface To configure a VLAN subinterface (VLAN ID) using Device Manager, follow these steps: Step 1 Step 2 Step 3 Step 4 Step 5 Step 6 Select Interface > Ethernet and iSCSI. Click the Sub Interfaces tab. Select the Gigabit Ethernet subinterface on which 802.1Q should be used. Click the Edit IP Address button. Enter the IPv4 address and subnet mask for the Gigabit Ethernet interface. Click Create to save the changes or you may click Close. Interface Subnet Requirements Gigabit Ethernet interfaces (major), subinterfaces (VLAN ID), and management interfaces (mgmt 0) can be configured in the same or different subnet depending on the configuration (see Table 53-1). Table 53-1 Subnet Requirements for Interfaces Interface 1 Gigabit Ethernet 1/1 Interface 2 Gigabit Ethernet 1/2 Gigabit Ethernet 1/1.100 Gigabit Ethernet 1/2.100 Gigabit Ethernet 1/1.100 Gigabit Ethernet 1/2.200 Gigabit Ethernet 1/1 Gigabit Ethernet 1/1.100 mgmt0 mgmt0 Gigabit Ethernet 1/1.100 Gigabit Ethernet 1/1 Same Subnet Allowed Yes Yes No No No No Notes Two major interfaces can be configured in the same or different subnets. Two subinterfaces with the same VLAN ID can be configured in the same or different subnets. Two subinterfaces with different VLAN IDs cannot be configured in the same subnet. A subinterface cannot be configured on the same subnet as the major interface. The mgmt0 interface cannot be configured in the same subnet as the Gigabit Ethernet interfaces or subinterfaces. Note The configuration requirements in Table 53-1 also apply to Ethernet PortChannels. OL-17256-03, Cisco MDS NX-OS Release 4.x Cisco MDS 9000 Family Fabric Manager Configuration Guide 53-5
