S5110在端口下静态绑定ip和mac不生效

S5110版本为Version 5.20.99, Release 1113，g1/0/12和g1/0/13接口配置如下

interface GigabitEthernet1/0/12
 port access vlan 1015
 loopback-detection enable
 arp filter source 172.18.115.254
 ip source binding ip-address 172.18.115.11 mac-address 507b-9d76-4a4f
 ip verify source ip-address mac-address

interface GigabitEthernet1/0/13
 port access vlan 1015
 loopback-detection enable
 arp filter source 172.18.115.254
 ip source binding ip-address 172.18.115.13 mac-address 8cec-4b74-b4b3
 ip verify source ip-address mac-address

mac地址如下

0023-24a3-6c11  1015     Learned         GigabitEthernet1/0/12     AGING
507b-9d76-4a4f  1015     Learned         GigabitEthernet1/0/12     AGING

8cec-4b74-b4b3  1015     Learned         GigabitEthernet1/0/13     AGING

但是在S5110上联的核心S7506上看到的ARP信息为

172.18.115.13   0023-24a3-6c11 1015       BAGG22                   1194  D

对于IP地址172.18.115.13 和mac地址 8cec-4b74-b4b3的绑定并未生效
