我想用SnmpSharpNet 获取路由器的mac地址,现在只能获取到sysDescr等叶子节点的信息,如何获得mac地址啊?

请各位大侠帮忙~~

获取mac需要使用get-next读取,而上面的只能用get读取,所以错误

SNMP Version 1 GET-NEXT Example

using System;
using System.Net;
using SnmpSharpNet;

namespace sharpwalk

    {

获取交换机端口vlan id代码:

先要得到该设备上的vlan列表,查找vtpVlanIfIndex(OID: 1.3.6.1.4.1.9.9.46.1.3.1.1.18)

将上面的  Oid rootOid = new Oid("1.3.6.1.2.1.2.2.1.2"); // ifDescr中换成

      Oid rootOid = new Oid("1.3.6.1.4.1.9.9.46"); // vlain id 好像是这个,需要一个个试一下,待修改,这个OID不在mib2中,用mib浏览器是找不到的,而在mib2上面一层,SMI树中

  使用此OID,得到的结果是  “端口”--》“vlan id”,eg:2 --》123
