Monitoring the ReachNXT 100-8t
When the ReachNXT 100-8t is operational, it is visible in your network either from the uplinked
ExtremeXOS switch or using EPICenter network management software. The ReachNXT 100-8t sends
LLDP Data Units (LLDPDUs) to the uplinked switch every 30 seconds. The LLDPDUs contain
type-length-value elements (TLVs) for Chassis ID, Port ID, TTL, System Name, and System Description.
For troubleshooting, you can use ExtremeXOS CLI commands or SNMP to query the LLDP neighbor
database or to determine the PoE status of the ReachNXT 100-8t. See Chapter 5, “Troubleshooting” for
more information.
Upgrading Firmware on the ReachNXT 100-8t
You can upgrade the firmware on the ReachNXT 100-8t either directly from the uplinked ExtremeXOS
switch, or from a DHCP/TFTP server on your network. The following firmware upgrade methods are
supported:
● ExtremeXOS switch-based
An XMOD package containing the updated firmware is installed on the uplinked ExtremeXOS
switch. Then the firmware upgrade process is triggered on the ReachNXT 100-8t, causing the
contents of the XMOD package to be downloaded to the ReachNXT 100-8t and installed.
This upgrade method requires that the uplinked switch be running ExtremeXOS 12.2 or later.
● Network-based
The firmware image is placed on an external DHCP/TFTP server, and the ReachNXT 100-8t connects
to the server and downloads the firmware over a VLAN configured for ReachNXT firmware
upgrades.
This method does not require a specific ExtremeXOS version.
See “Upgrading the ReachNXT 100-8t Firmware” on page 15 for firmware upgrade instructions.
