This section shows example configurations for both external switches for L2 connections to the SmartFabric.
General settings
Configure the hostname, OOB management IP address, and OOB management route as shown in the following example.

Configure VLANs
Create the VLANs for different networks as described in Table 2. To route traffic from the external switches to other external networks, assign a unique IP address on each switch and configure Virtual Router Redundancy Prototcol (VRRP) to provide gateway redundancy. Set the VRRP priority. The switch with the highest priority value becomes the master VRRP router. Assign the same virtual address to both switches.

Configure interfaces
Configure the interfaces for connections to the SFS leaf switches. In this example, interfaces 1/1/51 and 1/1/52 are configured in VLT port channel 100. To set port channel 100 as an LACP port channel, use the channel-group 100 mode active command.
To enable the port channel to carry traffic for multiple VLANs, use the switchport mode trunk command. Configure the port channel as tagged on:
- VLAN 1801 (Isilon network)
- VLAN 1811 (External Management VLAN)
- VLAN 1814 (VM_Network_A)
- VLAN 1815 (VM_Network_B)
- VLAN 1820 (PowerStore network)
Optionally, to enable forwarding of jumbo frames, use the MTU 9216 command.
In this example, interface 1/1/1 on each external switch is configured in VLT port channel 1 for connections to the DNS/NTP server. To set port channel 1 as an LACP port channel, use the channel-group 1 mode active command.
Configure ports that are directly connected to nodes, servers, or other endpoints as STP edge ports. As a best practice, flow control settings remain at their factory defaults as shown in the following example.

Configure VLT
This example uses interfaces 1/1/49 and 1/1/50 for the VLTi. Remove each interface from L2 mode by using the no switchport command.
Create the VLT domain. The backup destination is the OOB management IP address of the VLT peer switch. Configure the interfaces used as the VLTi with the discovery-interface command.
As a best practice, use the vlt-mac command to manually configure the same VLT MAC address on both the VLT peer switches. This step improves VLT convergence time when a switch is reloaded.
If you do not configure a VLT MAC address, the MAC address of the primary peer is used as the VLT MAC address on both switches.
When the configuration is completed, use the end and write memory commands to exit configuration mode and save the configuration.
