Unit 1: Network Infrastructure
This will allow you to demonstrate your networking skills, knowledge, and abilities, with a focus on enterprise-level switching, routing, and multicast components that support cross-platform (inter)operability and integration with the most recent software-defined technologies.
Layer 2 EtherChannel
Before putting EtherChannel into action in a network, it is important to lay out the following procedures that are required to ensure its success:
- In order to begin, you will need to determine which ports on both switches will be utilized for the EtherChannel. In addition to ensuring that the appropriate connections are available, this task assists in determining whether or not there are any problems with the prior configurations on the ports.
- The suitable protocol, such as PAgP or LACP, should be identified for each interface. Additionally, each interface should be assigned a channel group number in order to associate all of the specified interfaces with a port group. Furthermore, the interface should be configured that negotiation should take place.
- To ensure that both sides of the EtherChannel have formed and are supplying aggregated bandwidth, it is necessary to check once the connections have been established.
For the purpose of setting EtherChannel interfaces, the following recommendations and limits should be followed:
EtherChannel support: All Ethernet interfaces on all modules can work with EtherChannel. The interfaces don’t even have to be on the same module or physically next to each other.
Speed and duplex: Set up all of an EtherChannel’s connections to work at the same speed and in the same duplex mode. Also, if an interface in the bundle goes down, it’s seen as a broken link, and traffic will go through other links in the bundle.
