Upgrade from an External Image Server

This section provides the steps for upgrading the GigaVUE nodes and clusters from an image stored on an external server. The image can be transfered from the server to the node using either SCP or TFTP file protocols.

In a cluster configuration, to upgrade the software on the GigaVUE nodes, all the relevant images must be available to GigaVUE‑FM. All nodes should be updated to the same version of software.

To upgrade a node or a cluster from an image stored on an external image server, do the following:

1.

Upload the image to the external image server to make it available to GigaVUE‑FM.

To obtain software images, register on the Gigamon Customer Portal and download the software. You must provide the serial number for each node you want to update.

To view the chassis serial number, login to GigaVUE-FM and select Chassis from the navigation pane. Click List View.

2.

Click Physical on the top navigation link.

On the Physical Nodes page, select one or more nodes or clusters to upgrade.
