问题：

交换机S5700与防火墙USG5500无法对接Eth-trunk LACP-static模式，两端正常配置后，端口状态显示错误，Eth-trunk端口无法up 。

问题描述：

交换机侧 GE0/0/5和GE 0/0/6 组成Eth-trunk3 通过LACP-static与防火墙对接；防火墙侧采用端口GE0/0/1和GE0/0/2组成Eth-trunk1通过LACP-static与交换机对接。

交换机侧配置：

interface Eth-Trunk3

port link-type trunk

undo port trunk allow-pass vlan 1

port trunk allow-pass vlan 301 321

mode lacp-static

#

interface GigabitEthernet0/0/5

eth-trunk 3

#

interface GigabitEthernet0/0/6

eth-trunk 3

#

防火墙侧的配置：

interface Eth-Trunk1

alias Eth-Trunk1

mode lacp-static

#interface GigabitEthernet0/0/1

undo enable snmp trap updown physic-status

eth-trunk 1

lacp peer-portno 0002

#

interface GigabitEthernet0/0/2

undo enable snmp trap updown physic-status

eth-trunk 1

lacp peer-portno 0003

#

交换机侧端口状态显示：

单独查看物理端口，其物理状态UP；
