Interface description is one of the most important configuration when bringing up interfaces between two devices. In a bundle or port-channel interface, there is a way to find the partner interface or which member in that bundle is your interface or port is connected especially if there’s no description or outdated. Here are the steps and commands to find LACP partner interface or port in Cisco Router and Switch Fig1.1 (Cisco IOS-XR)     Assuming we have this Fig1.1, two…

As per Cisco documentation: A virtual PortChannel (vPC) allows links that are physically connected to two different Cisco Nexus devices to appear as a single Port Channel to a third device. The third device can be a Cisco Nexus 2000 Series Fabric Extender or a switch, server, or any other networking device. A vPC can provide Layer 2 multipathing, which allows you to create redundancy by increasing bandwidth, enabling multiple parallel paths between nodes and load-balancing traffic where alternative paths…

Link Aggregation Control Protocol or  IEEE 802.3ad (LACP) is an open standard of Ethernet link aggregation protocol. It is a method used by routers/switches to automatically establish link aggregation groups or LAG ( sometimes called as channel groups, bundle or port-channels). Here’s LACP configuration examples for different Cisco platforms using LACP active mode, where it places a port into an active negotiating state and sending LACPDU (Data units) at regular intervals to seek out partners IOS (Catalyst 4500) Configuration: interface…
