Link Aggregation Configuration
This chapter contains a complete sample Link Aggregation Group configuration.
LACP is based on the 802.3ad IEEE specification. It allows bundling of several physical interfaces to form a single logical channel providing enhanced performance and redundancy. The aggregated interface is viewed as a single link to each switch. The spanning tree views it as one interface and not as two or three interfaces. When there is a failure in one physical interface, the other interfaces stay up and there is no disruption. Traffic can be load balanced within an LACP trunk group in a controlled manner using the hashing algorithm.
The maximum number of physical Ethernet links in a single logical channel depends upon the hardware support.
Table 12-1 lists the number of LAG groups per device and number of port settings per LAG group for the QMX, QUX, and QAX hardware.
Table 12-1: Number of LAGs and ports supported
Hardware | Number of LAG groups per device | Number of port settings per LAG group |
|---|
QMX | 256 | 64 |
QUX | 32 | 64 |
QAX | 256 | 64 |
Note:
• Physical interfaces inherit the properties of LAG port once it is attached to be part of LAG, irrespective of the configuration present on the physical interface.
• In case of dynamic LAG and static LAG, member ports could be moved from one LAG to another LAG, without unconfiguring the member port.
• LAG port should be configured as a switch or router port, before adding member ports into it.
