华为核心交换机：S5720S-36C-EI-AC 管理IP：172.30.5.1
华为桌面交换机：S5700S-52P-LI-AC 管理IP：172.30.5.10
核心交换机的 G0/0/24，G1/0/24 聚合与
桌面交换机的 G0/0/47 ,G0/0/48的聚合口通过trunk互联
核心交换机配置：
[SW_CORE_5.1]interface eth-trunk 1
[SW_CORE_5.1-eth-trunk1]port link-type trunk
[SW_CORE_5.1-eth-trunk1]port trunk allow-pass vlan all
[SW_CORE_5.1-eth-trunk1]des conn_sw_acc_5.10
