snmpwalk-MIB of S5700-idc-stack
IF-MIB:.iso.org.dod.internet.mgmt.mib-2.interfaces.ifTable.ifEntry.ifDescr
OID：.1.3.6.1.2.1.2.2.1.2
针对普通网络设备的端口，MIB的相关定义是Interface组，主要管理如下信息：
ifIndex 端口索引号
ifDescr 端口描述
ifType 端口类型
ifMtu 最大传输包字节数
ifSpeed 端口速度
ifPhysAddress 物理地址
ifOperStatus 操作状态
ifLastChange 上次状态更新时间
*ifInOctets 输入字节数
*ifInUcastPkts 输入非广播包数
*ifInNUcastPkts 输入广播包数
*ifInDiscards 输入包丢弃数
*ifInErrors 输入包错误数
*ifInUnknownProtos 输入未知协议包数
*ifOutOctets 输出字节数
*ifOutUcastPkts 输出非广播包数
*ifOutNUcastPkts 输出广播包数
*ifOutDiscards 输出包丢弃数
*ifOutErrors 输出包错误数
ifOutQLen 输出队长
其中，*号标识的是与网络流量有关的信息。

在MIB-2功能组的接口组中，如果对象ifAdminStatus的值为up(1) ，而ifOperStatus的值down(2) ，则该接口处于故障状态。如果对象if_AdminStatus、ifOperStatus的值均为up(1) ，则接口处于正常状态；如果对象ifAdminStatus、ifOperStatus的值均为down(2) ，则接口处于停机状态；如果对象ifAdminStatus、ifOperStatus的值均为Testing(3) ，则接口处于测试状态。
