Table 41 interface-group Commands Summary (continued)

COMMAND

DESCRIPTION

loadbalancing-index

Use this command only if you use least load first or spill-over as the

<inboundoutboundtotal>

trunk’s load balancing algorithm.

 

Set either inbound, outbound, or total (outbound and inbound)

 

traffic to which the ZyWALL 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 {normaltrunk}

Sets the mode for a trunk. Do this first in the trunk’s sub-command

 

mode.

move <1..8> to <1..8>

Changes a the interface order in a trunk.

[no] interface {numinterface-name}

Removes an interface from the trunk.

system default-interface-group group-name

Sets the ZyWALL 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 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 enable SNAT or not. The ZyWALL

 

performs SNAT by default for traffic going to or from the WAN

 

interfaces.

 

 

show system default-interface-group

Displays the WAN trunk the ZyWALL first attempts to use.

7.5 Trunk Command Examples

The following example creates a weighted round robin trunk for Ethernet interfaces ge1 and ge2. The ZyWALL sends twice as much traffic through ge1.

Router# configure terminal

Router(config)# interface-group wrr-example

Router(if-group)# mode trunk

Router(if-group)# algorithm wrr

Router(if-group)# interface 1 ge1 weight 2

Router(if-group)# interface 2 ge2 weight 1

Router(if-group)# exit

Router(config)#

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 sends new session traffic

through the least utilized of these interfaces.

Router# configure terminal

Router(config)# interface-group llf-example

Router(if-group)# mode trunk

Router(if-group)# algorithm llf

Router(if-group)# interface 1 ge3

Router(if-group)# interface 2 vlan5

Router(if-group)# loadbalancing-index outbound

Router(if-group)# exit

Router(config)#
