Network-Based Upgrade

An alternate method of upgrading the ReachNXT 100-8t uses an external DHCP/BootP and TFTP
server. This method may be more flexible for larger-scale deployments, since the firmware image can be
served from a single server. This method is illustrated in
The network-based upgrade relies on existing capabilities in the ExtremeXOS switch to connect
ReachNXT 100-8t units to an external server over a VLAN configured for this purpose. The VLAN to
use for this is conveyed to the ReachNXT 100-8t in the LLDP VLAN Name TLV. If the ReachNXT 100-8t
receives this TLV, it sends a BootP request on that VLAN, receives a BootP reply, and performs a TFTP
GET action to obtain the new firmware image file over the configured VLAN. If the server is not on the
same VLAN, the ExtremeEXOS BootP Relay capability can be used to re-direct BootP messages to the
server.
