For any queries, contact technical support VLT Upgrade Procedure Follow this procedure to upgrade the system from release 9.4(2.8) to the latest version in a VLT setup: 1. Upgrade the system-flash partition A or B with the new image on both VLT peers.On both the VLT peers, set Primary boot parameter to boot the system from upgraded system flash partition [A or B].You can enter one of the following options:flash -- Copies from flash file system (flash://filepath).ftp -- Copies from remote file system (ftp://userid:password@hostip// filepath).scp -- Copies from remote file system (scp://userid:password@hostip//filepath).tftp -- Copies from remote file system (tftp://hostip/filepath). EXEC Privilege Mode upgrade system [flash: | ftp: | scp: | tftp: | usbflash:] [A: | B:] 2. Reload or power-cycle one of the VLT peers (For Example, Peer 2). EXEC Privilege Mode reload or power cycle 3. Wait for Peer 2 to come up; VLT adjacency will be established. (Peer 2 - new image and Peer 1 - old image). 4. Wait for the Peer 2 to bring up all VLT LAG ports. Use the command show vlt detail to confirm all VLT ports in the local chassis are active. EXEC Privilege Mode show vlt detail 5. Following upgrade, use the write memory command to save the running-config to memory. EXEC Privilege Mode write memory 6. Ensure both the nodes are now forwarding traffic. 7. When all VLT ports are active on the Peer 2, repeat steps 2 through 5 for the Peer 1. 9 Documentation Corrections This section describes the errors identified in the current release of the Dell Networking OS. The router bgp command allows you to configure only one L3 interface with an IPv4 address. The Configuration guide does not mention this limitation and will be corrected in the next release of the guide.
