Enable RSTP as a precaution against creating a networking loop. S4048-Leaf 1 is configured as the primary RSTP root bridge using the bridge-priority 0 command. S4048-Leaf 2 is configured as the secondary RSTP root bridge using the bridge-priority 4096 command. This ensures that leaf 1 will always be the root bridge. The no iscsi enable command is issued to ensure that iSCSI snooping is disabled. S4048-ON Leaf 1 configure terminal hostname S4048-Leaf1 interface mgmt 1/1/1 no ip address dhcp ip address 100.67.170.15/24 management route 0.0.0.0/0 100.67.170.254 no iscsi enable spanning-tree mode rstp spanning-tree rstp priority 0 S4048-ON Leaf 2 configure terminal hostname S4048-Leaf2 interface mgmt 1/1/1 no ip address dhcp ip address 100.67.170.14/24 management route 0.0.0.0/0 100.67.171.254 no iscsi enable spanning-tree mode rstp spanning-tree rstp priority 4096 Configure the VLT interconnect between S4048-Leaf1 and S4048-Leaf2. In this configuration, remove each interface from layer 2 mode with the no switchport command for interfaces eth 1/1/53-1/1/54. Once this is done, create the VLT domain, add the backup destination, and add the interfaces participating in VLTi. Finally, enable VLT peer routing on each switch. Once VLT is enabled, it will dynamically change the MTU settings for the VLTi to a value of 9216. Isilon's OneFS supports and recommends the use of jumbo frames. Note: Refer to Isilon Network Design Considerations for more information on specific protocols as they relate to OneFS. 25 Dell EMC Networking with Isilon Front-End Deployment and Best Practices Guide | version 1.0
