Note:
Ethernet Bonding
Ethernet 1 and Ethernet 2 can be bonded to support redundancy (Active Backup),
aggregation (802.3ad), and load balancing. Disabled by default. Ethernet Bonding
requires that Eth1 and Eth2 must be set to Static IP.
Note:
If Ethernet Bonding is enabled, assigning individual IP Addresses to Device
Ports is not supported.
Ethernet Bonding
Status (Link)
Click the link to access Ethernet bonding status information. Ethernet 1 and
Ethernet 2 can be bonded to support redundancy (Active Backup), aggregation
(802.3ad), and load balancing. Disabled by default. Ethernet Bonding requires that
Eth1 and Eth2 must be set to Static IP.
Note:
If Ethernet Bonding is enabled, assigning individual IP Addresses to Device
Ports is not supported.

Hostname
The default host name is
emgXXXX
, where
XXXX
is the last 4 characters of the
hardware address of Ethernet Port 1. There is a 64-character limit (contiguous
characters, no spaces). The host name becomes the prompt in the command line
interface.
Domain
If desired, specify a domain name (for example, support.lantronix.com). The domain
name is used for host name resolution within the EMG unit. For example, if abcd is
specified for the SMTP server, and
mydomain.com
is specified for the domain, if
abcd
cannot be resolved, the EMG attempts to resolve
abcd.mydomain.com
for
the SMTP server.
#1 - #3
Configure up to three name servers with an IPv4 or IPv6 address. #1 is required if
you choose to configure DNS (Domain Name Server) servers. The EMG will attempt
to contact each DNS server in the order that they are given. If a DNS server cannot
be reached, the next DNS server will be tried. If a DNS server is reachable, but does
not resolve a hostname, no other attempts will be made to resolve the hostname
using the remaining DNS servers.
The first three DNS servers acquired via DHCP through Eth1 and/or Eth2 display
automatically.
#1 - #3
Displays the IP address of the name servers if automatically assigned by DHCP.
Prefer IPv4 DNS
Records
If enabled, IPv4 DNS records will be preferred when DNS hostname lookups are
performed. Otherwise IPv6 records will be preferred (when IPv6 is enabled). Enabled
by default.
