Configuring Link Aggregation 编辑

Link aggregation combines data coming from multiple ports into a single high-speed link. Configuring link aggregation increases the capacity and availability of the communication channel between the Citrix ADC appliance and other connected devices. An aggregated link is also referred to as a “channel.” You can configure the channels manually, or you can use Link Aggregation Control Protocol (LACP). You cannot apply LACP to a manually configured channel, nor can you manually configure a channel created by LACP.

When a network interface is bound to a channel, the channel parameters have precedence over the network interface parameters. (That is, the network interface parameters are ignored.) A network interface can be bound only to one channel.

When a network interface is bound to a channel, it drops its VLAN configuration. When network interfaces are bound to a channel, either manually or by LACP, they are removed from the VLANs that they originally belonged to and added to the default VLAN. However, you can bind the channel back to the old VLAN, or to a new one. For example, if you bind the network interfaces 1/2 and 1/3 to a VLAN with ID 2, and then bind them to a channel LA/1, the network interfaces are moved to the default VLAN, but you can bind them back to VLAN 2.

Configuring Link Aggregation Manually

When you create a link aggregation channel, its state is DOWN until you bind an active interface to it. You can modify a channel at any time. You can remove channels, or you can enable/disable them.

CLI procedures

To create a link aggregation channel by using the CLI:

At the command prompt, type:

• add channel <id> [-ifnum <interfaceName> …] [-state ( ENABLED | DISABLED )] [-speed <speed>] [-flowControl <flowControl>] [-haMonitor ( ON | OFF )][-tagall ( ON | OFF )] [-ifAlias <string>] [-throughput <positive_integer>] [-bandwidthHigh <positive_integer> [-bandwidthNormal <positive_integer>]]
• show channel

Example:

> add channel LA/1 -ifnum 1/8
Done
