cacti在控制台的查询结果和在服务器用snmpwalk查询结果不一致是怎么回事

在控制台进行详细查询是结果如下：
+ Located input field 'ifDescr' [walk]
+ Executing SNMP walk for data @ '.1.3.6.1.2.1.2.2.1.2'

而在服务器用snmpwalk结果如下：
]# snmpwalk -v 2c -c public 172.16.76.14 .1.3.6.1.2.1.2.2.1.2
IF-MIB::ifDescr.1 = STRING: Ethernet0/0/1

IF-MIB::ifDescr.23 = STRING: Ethernet0/0/23
IF-MIB::ifDescr.24 = STRING: Ethernet0/0/24
IF-MIB::ifDescr.25 = STRING: Ethernet0/0/25
IF-MIB::ifDescr.26 = STRING: Ethernet0/0/26
IF-MIB::ifDescr.27 = STRING: Ethernet0/0/27
IF-MIB::ifDescr.28 = STRING: Ethernet0/0/28
IF-MIB::ifDescr.2002 = STRING: Vlan1001


请问这是怎么回事？

该设备为神州数码的3950-28CT，尝试用solarwind之类的其他监控软件可以正常读取端口描述
