What are the EtherChannel limitations?
A limitation of EtherChannel is that all the physical ports in the aggregation group must reside on the same switch except in the case of a switch stack, where they can reside on different switches on the stack.
Should you use LACP?
LACP lets devices send Link Aggregation Control Protocol Data Units (LACPDUs) to each other to establish a link aggregation connection. Both devices must support LACP for you to set up a dynamic LAG between those devices. We recommend using LACP instead of a static LAG whenever both devices support LACP.
What is an advantage of using LACP?
It allows directly connected switches to negotiate an EtherChannel link. It provides a simulated environment for testing link aggregation. It decreases the amount of configuration that is needed on a switch.
Does LACP do load balancing?
The LACP Single Fault Direct Load Balance Swapping feature is enabled using the CLI command lacp direct-loadswap in port-channel configuration mode.
Why does LACP not work on Lag ports?
The teaming and failover health check does not work for LAG ports. LACP checks the connectivity of the LAG ports. The enhanced LACP support works correctly when only one LAG handles the traffic per distributed port or port group.
How is the LACP administrative key value determined?
LACP administrative key LACP automatically configures an administrative key value equal to the channel group identification number on each port configured to use LACP. The administrative key defines the ability of a port to aggregate with other ports. A port’s ability to aggregate with other ports is determined by these factors:
How does link aggregation Control Protocol ( LACP ) work?
Within the IEEE specification, the Link Aggregation Control Protocol (LACP) provides a method to control the bundling of several physical ports together to form a single logical channel.
Is the LACP support on a vSphere distributed switch supported?
The LACP support on a vSphere Distributed Switch lets network devices negotiate automatic bundling of links by sending LACP packets to a peer. However, the LACP support on a vSphere Distributed Switch has limitations. The LACP is not supported with software iSCSI port binding. iSCSI multipathing over LAG is supported, if port binding is not used.
