Question

如何通过SNMP获得此结果？

Answer 1

这有点晚了，但在研究类似的东西时，我在思科论坛上看到了这篇帖子。它在IEEE8023-LAG-MIB中报告以下对象：

IEEE8023-LAG-MIB::dot3adAggPortSelectedAggID.28 = INTEGER: 337
IEEE8023-LAG-MIB::dot3adAggPortSelectedAggID.82 = INTEGER: 337
IEEE8023-LAG-MIB::dot3adAggPortAttachedAggID.28 = INTEGER: 337
IEEE8023-LAG-MIB::dot3adAggPortAttachedAggID.82 = INTEGER: 337
ifName.28 = Gi2/4
ifName.82 = Gi3/10
ifName.337 = Po1

在相同的环境中，show etherchannel summary命令将导致：

+------+-------------+-----------+---------------------------------+
| Group|Port-channel |Protocol   | Ports                           |
+------+-------------+-----------+---------------------------------+
|  1   | Po1(SU)     | LACP      | Gi2/4(P)       Gi3/10(P)        |
+------+-------------+-----------+---------------------------------+

对于PAGP协议，有一个表pagpEtherChannelTable，其中pagpGroupIfIndex指向公共虚拟端口
