7: Networking Ethernet Bonding Ethernet Bonding Status (Link) Reverse Path Filter 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. 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.

In this mode, each incoming packet is tested against the forward information base (FIB), and if the network interface is not the best reverse path, the packet check will fail and failed packets are discarded. Hostname & Name Servers Hostname Domain 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. 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. DNS Servers #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. Multiple DNS servers can be configured or acquired via DHCP, however a maximum of 3 can be active (or in use) at any time; the active DNS servers are labeled in red. DHCP-Acquired DNS Servers #1 - #3 Prefer IPv4 DNS Records Displays the IP address of the name servers if automatically assigned by DHCP. 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.

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.

Click

Back to Network Settings

link to return to the Network Settings page.

Reverse Path Filter

Select this option to allow the Reverse Path Filter mode, which is defined in RFC

3704. In this mode, each incoming packet is tested against the forward information

base (FIB), and if the network interface is not the best reverse path, the packet

check will fail and failed packets are discarded.

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.

Multiple DNS servers can be configured or acquired via DHCP, however a maximum

of 3 can be active (or in use) at any time; the active DNS servers are labeled in red.

#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.
