Huawei H35-480_V3.0 Dumps Questions Answers

The X2 interface is a signaling interface used in LTE networks to interconnect two eNodeBs (LTE base stations) to support handover and other functions. In the inter-site DC solution, the X2 interface can also be used to implement the transmission interconnection between the LTE and NR sites.

In order to ensure smooth handover and service continuity between the LTE and NR sites, it is necessary to meet the requirement of low transmission delay, which is typically <20ms. This low delay requirement is important to ensure that the handover can be completed quickly and without interruption to the ongoing service.

According to the Huawei SA Networking Product Design Guide (https://www.huawei.com/en/doc/e_huaweidoc/pdf/HW_051525), VLAN scanning is used to detect VLANs in a network. The VLAN scanning process is initiated on the base station and requires the base station to send a query to the Layer 2 switch. The query contains the VLAN ID, and the Layer 2 switch then responds with the list of interfaces that are associated with that VLAN ID. Configuration on the LMT is used to configure the VLAN and assign it to the base station. Finally, remote DHCP assignment is used to assign IP addresses to the base station from the DHCP server.
