In the configuration of a Huawei switch, port aggregation is called ETH-trunk. Multiple physical ports are combined into a logical port. The purpose is to increase the bandwidth and redundant traffic load. There are two working modes: manual load balancing and lacp.
Lacp mode is a link aggregation mode that uses lacp protocol to negotiate aggregation parameters and determine active and inactive interfaces. You need to manually create ETH-trunk and manually add the ETH-trunk member interface. The lacp protocol negotiate to determine the active and inactive interfaces.
Aggregation is a good concept. It is okay to configure the aggregation between a vswitch and a vswitch. In today's era when virtualization is rampant, esxi also supports network load balancing. After configuring the default virtual switch, you do not need to set the physical switch.
Now, the VM in the esxi host implements the multicast mode used by the windows2008 NLB network, and static ARP binding is performed on the switch. Can esxi support the two ports of the Huawei physical switch as port aggregation?
Refer to the following official VMware documents:
Note:: Many requirements need to be considered before any form of link aggregation is implemented. For more information about these requirements, see Host Requirements for Link aggregation for esxi and ESX (1001938 ).
Concept of link aggregation:
Etherchannel: This is a link aggregation (Port relay) method, it is used to provide fault tolerance and high-speed connections between vswitches, routers, and servers (by combining two to eight physical Ethernet connections to create logical Ethernet connections through other failover links ). For more information about Cisco etherchannel, see etherchannel introduction provided by Cisco.
Lacp or IEEE 802.3ad: Lacp is used to control multiple physical port packages to form a single logical channel. Lacp allows network devices to negotiate automatic connection packets by sending lacp packets to peer devices (or directly connecting devices with lacp. For more information about lacp, see link aggregation control protocol whitepaper provided by Cisco.
Note: lacp is only supported in vsphere 5.1 and 5.5 or Cisco nexus 1000 V that uses vsphere distributed switch (VDS.
Etherchannel and 802.ad: The etherchannel and IEEE 802.3ad standards are very similar and achieve the same goal. However, there are also some differences between them. The most obvious difference is that etherchannel is a Cisco proprietary product, while 802.3ad is an open standard.
For more information about etherchannel implementation, see the understanding etherchannel load balancing and redundancy on Catalyst switches article provided by Cisco.
Solutions supported by etherchannel:
Connection from one IP address to multiple IP addresses. (Host a initiates two connection sessions to host B and host C)
Connect multiple IP addresses to multiple IP addresses. (Host a and host B initiate multiple connection sessions to host C and host D)
Note:: One IP address to one IP address cannot be connected on multiple NICs. (A connection Session Initiated by host a to host B only uses one NIC ).
Compatible with all esxi/esx vlan configuration modes: VST, EST, and VGT. For more information about these modes, see VLAN configuration on Virtual Switch, physical switch, and virtual machines (1003806 ).
Supported Cisco configuration: Enable etherchannel mode-(only enable etherchannel)
Supported HP configurations: Relay Mode
Supported switch aggregation algorithms: IP-SRC-DST (abbreviated IP-source-destination)
Supported vswitch Nic combination mode: IP hash
Note:: The unique Load Balancing option of vswitch or vdistributed switch that can be used with etherchannel is IP hash:
Do not use Signal Detection with IP hash load balancing.
Do not use IP hash load balancing to configure standby or unused upstream links.
VMware only supports one etherchannel for each vswitch or vnetwork distributed switch (VDS.
According to official information, port aggregation only supports distributed switches and Cisco nexus 1000 V. These two switches only support the vcenter environment. A single esxi host does not support port aggregation.
