2.1.e (iii) Load-balancing Flows can become polarized (like CEF polarization) to a specific link if ther flow is not classified as diverse. So depending on the etherchannel load balancing hashing algorithm, we might get polarization. By default Cisco devices just hash the flow based on the source mac address, which is susceptible to polarization, thus …
2.1.e (ii) Layer 2, Layer 3
2.1.e (ii) Layer 2, Layer 3 Etherchannels are independent from their port types. Meaning they can be access ports or trunks, it does not matter. You can negotiate an etherchannel between a L2 (switch) and a L3 device (server/router/whatever). Or you can negotiate one to another switch L2 to L2. Note the order of operations …
2.1.e (i) LACP, PAgP, manual
2.1.e (i) LACP, PAgP, manual Configuration: When configuring a channel group we have the options of LACP, PAGP, or just ON (static). Here's an example of ports g0/1-2 in a port channel: en conf t int range g0/1-2 channel-group 1 mode <active | auto | desirable | on | passive> These obviously do different things: …
2.1.e Implement and Troubleshoot EtherChannel
2.1.e Implement and Troubleshoot EtherChannel Etherchannel, port-channel, team, LAG, and in vendor neutral groups (trunk) all refer to the static or negotiated bundling of links. Etherchannels provide at the heart provide us link redundancy. If a link fails it's automatically removed from the etherchannel. When we configure an etherchannel we group links into a …
