Each field is described in the following table.

LABEL
DESCRIPTION
General Settings
Enable Interface
Select this to enable this interface. Clear this to disable this interface.
Interface Properties
Interface Type
Select one of the following option depending on the type of network to which the Zyxel
Device is connected or if you want to additionally manually configure some related
settings.
internal
is for connecting to a local network. Other corresponding configuration options:
DHCP server and DHCP relay. The Zyxel Device automatically adds default SNAT settings for
traffic flowing from this interface to an external interface.
external
is for connecting to an external network (like the Internet). The Zyxel Device
automatically adds this interface to the default WAN trunk.
For
general
, the rest of the screen’s options do not automatically adjust and you must
manually configure a policy route to add routing and SNAT settings for the interface.
Interface Name
This field is read-only if you are editing the interface. Enter the name of the LAG interface.
The format is lag
x
, where
x
is 0 - 3. For example, lag0, lag1, and so on.
Zone
Select the zone to which the interface is to belong. You use zones to apply security settings
such as security policy, IDP, remote management, anti-virus, and application patrol.
Description
Enter a description of this interface. You can use alphanumeric and
()+/:=?!*#@$_%-
characters, and it can be up to 60 characters long. Spaces are allowed, but the string
can’t start with a space.
LAG Configuration
Mode
Select a Mode for this LAG interface. Choices are as follows:
•
active-backup
where only one slave in the LAG interface is active and another slave
becomes active only if the active slave fails.
•
802.3ad
(IEEE 802.3ad Dynamic link aggregation) where Link Aggregation Control
Protocol (LACP) negotiates automatic combining of links and balances the traffic load
across the LAG link by sending LACP packets to the directly connected device that
also implements LACP. The slaves must have the same speed and duplex settings.
•
balance-alb
(adaptive load balancing) where traffic is distributed according to the
current load on each slave by ARP negotiation. Incoming traffic is received by the
current slave. If the receiving slave fails, another slave takes over the MAC address of
the failed receiving slave.
Link Monitoring
Select from
none
,
mii
or
arp
.
none
means no link monitoring is done.
mii
monitoring monitors the state of the local interface; it can’t tell if the link can transmit or
receive packets.
arp
monitoring sends ARP queries and uses the reply to know if the link is up and that traffic
is flowing over the link.
Miimom
This field displays for
mii
Link Monitoring. Set the link check interval in milliseconds that the
system polls the Media Independent Interface (MII) to get status.
Updelay
This field displays for
mii
Link Monitoring. Set the waiting time in milliseconds to confirm the
slave interface status is up.
Downdelay
This field displays for
mii
Link Monitoring. Set the waiting time in milliseconds to confirm the
slave interface status is down.
Xmit Hash Policy
This field displays in
802.3ad
Mode. This field sets the algorithm for slave selection according
to the selected TCP/IP layer.
LACP Rate
This field displays in
802.3ad
Mode. Select the preferred LACPDU packet transmission rate
(
slow
/
fast
) to request from 802.3ad partner.
ARP Interval
This field displays for
arp
Link Monitoring. Select the frequency of ARP requests sent to
confirm a that slave interface is up.
