15: Maintenance
The system administrator performs maintenance activities and operates the EMG using the
options for the Maintenance tab and additional commands on the command line interface.
Firmware & Configurations
The Firmware & Configuration page allows the system administrator to:
Configure the FTP, SFTP, or TFTP server that will be used to provide firmware updates and
save/restore configurations. (TFTP is only used for firmware updates and configurations
restored via the
Zero Touch Provisioning Configuration Restore feature
.)
Set up the location or method that will be used to save or restore configurations (Local Disk,
FTP, SFTP, NFS, CIFS, USB, HTTPS or SD card). Update the version of the firmware running
on the EMG unit.
Save a snapshot of all settings on the EMG device (save a configuration).
Restore the configuration, either to a previously saved configuration, or to the factory defaults.
Factory defaults can also be initiated by using an external storage device. See
with External Storage Device on page 335
Configurations can also be pushed to the EMG via the
HTTPS Push Configuration Restore
feature.
Zero Touch Provisioning Configuration Restore
The Zero Touch Provisioning feature allows a factory defaulted EMG to acquire a default
configuration from a DHCP server when it is booted. If ZTP will be performed in an untrusted
network, it is recommended that the Vendor Specific Information option using HTTPS and X.509
certificates be used. At boot-time, before the normal startup process, a unit will attempt to acquire
network parameters and a configuration file, first over Eth1, and then over Eth2 if Eth1 does not
receive any configuration download information from the local DHCP server.
The unit will send DHCP request over Eth1 and then over Eth2, with the following DHCP
options:
-
Vendor Specific Information
(option 43)
-
TFTP Server IP address list
(option 150, a Cisco proprietary option)
-
TFTP Server Name or IP address
(option 66)
-
Boot Filename
(option 67)
For more information on these options see
RFC 2132
RFC 5859
. To obtain Vendor
Specific Information (VSI), the console manager sends a
Vendor Class Identifier
(option 60)
of LantronixSLC8000 (for SLC8000 models) or
LantronixEMG
(for EMG models). The
console manager will use VSI suboption 1 (see format below) to determine the location of the
ZTP file.
If the DHCP Offer received from a DHCP server contains multiple options, they will be utilized
in this order:
a. Option
VSI/43
with suboption 1 (ZTP file location) will be used, and all other DHCP options
will be ignored.
