14.5 Trunk Command Examples
The following example creates a weighted round robin trunk for Ethernet interfaces ge1 and ge2.
The ZyWALL / USG sends twice as much traffic through ge1.
The following example creates a least load first trunk for Ethernet interface ge3 and VLAN 5, which
will only apply to outgoing traffic through the trunk. The ZyWALL / USG sends new session traffic
through the least utilized of these interfaces.
loadbalancing-index
<inbound|outbound|total>
Use this command only if you use least load first or spill-over as the
trunk’s load balancing algorithm.
Set either inbound, outbound, or total (outbound and inbound)
traffic to which the ZyWALL / USG will apply the specified algorithm.
Outbound traffic means the traffic travelling from an internal interface
(ex. LAN) to an external interface (ex. WAN). Inbound traffic means the
opposite.
mode {normal|trunk} Sets the mode for a trunk. Do this first in the trunk’s sub-command
mode.
move <1..8> to <1..8> Changes the interface order in a trunk.
[no] interface {num|interface-name} Removes an interface from the trunk.
system default-interface-group group-name Sets the ZyWALL / USG to first attempt to use the the specified WAN
trunk.
[no] system default-snat Enables or disables Source NAT (SNAT). When SNAT is enabled, the
ZyWALL / USG uses the IP address of the outgoing interface as the
source IP address of the packets it sends out through the WAN
interfaces.
show system default-snat Displays whether the ZyWALL / USG enable SNAT or not. The ZyWALL /
USG performs SNAT by default for traffic going to or from the WAN
interfaces.
show system default-interface-group Displays the WAN trunk the ZyWALL / USG first attempts to use.
