Where is the aggregation port on a Huawei switch

Huawei MA5683T is an aggregation Optical Line Terminal (OLT), it supports up to 6 service slots and can support a maximum of 12,000 subscribers (GPON). MA5683T has GICF/X2CS Uplink Board available for selection, and two power slot redundancy for DC power input. Ethernet link aggregation increases link bandwidth by bundling multiple physical links to form a logical link. Link aggregation can work in manual mode or Link Aggregation Control Protocol (LACP) mode. In manual mode, you must manually create an Eth-Trunk and add member interfaces to the Eth-Trunk. As shown in Figure 1, SwitchA and SwitchB are connected to the networks of VLAN10 and VLAN20, respectively, via Ethernet links, and there is a large amount of data traffic between SwitchA and SwitchB. Link aggregation has the following advantages:. Original operating mode: Two S5700s were configured with Eth-Trunk1, and the ports of the three lines that need to be communicated were added to Eth-Trunk1. Set the port to access to allow the corresponding VLAN to pass; so that the two floors of the network can communicate normally In this way. And there are two link aggregation types.
