7506x纳管onu问题

按照文档配置onu管理地址之后无法ping通onu地址，配置存在问题还是onu不支持

配置如下

interface Onu1/1/0/1:1

 bind onu-id sn H3CT000852E6

 bind onu-line-profile 1_1

 management-vlan 2255 

 undo shutdown management-vlan-interface

 ip address 172.23.255.230 255.255.255.0 gateway 172.23.255.254

 uni 2 vlan-mode tag pvid 2005

 uni 3 vlan-mode tag pvid 2005
