Hello @AjaS, Do you mean CAN bus ? which is "a controller area network"  If so, so the standard converters are NOT working as routers, they are in the physical layer of the OSI model as they  are used to convert electrical signals and physical media, but don’t do anything for data changes (as the fiber optical multimedia converters). Which means that you can consider them the same area using the same IP address range.   Note, that some converters have more higher functions than just converting the signals, so maybe you have to provide us the model of the used converter so that we can be more confident regarding the info.   Please don't forget to rate all helpful responses and mark solutions!

Hello @Alim670, This is a pretty good question, as a lot of people get confused from the algorithm being calculated by the means of etherchannel,  Let me first review 1 concept upon it, we can discuss your question, the concept is the load balance method you would like to choose for your traffic through the port channel, The methods can be one of the following: src-ip dst-ip src-mac  dst-mac and for these methods, the algorithm is going to check the most right bits (according to the number of links) to choose what link is going to be used, for example if the method used is src-ip, and the ip address is 10.1.10.1 so the last bit is 1, and your channel consists of 2 physical links, so the 1st link is going to be used, and so on!  but also you can use these methods: src-dst-ip src-dst-mac and for these methods, the algorithm is going to compare the most right bits by the XOR operation, for example if the method used is src-dst-ip, and the src ip is 10.1.10.1 while the dst ip is 10.1.10.2, and you use 3 links, so the algorithim will compare the 2 most right bits, for the src 01 while for the dst 10, 01 XOR 10 = 11, which is the most right 3rd bit, so the third link will be the one carrying the data. Now, after understanding that concept, and according to the 1st table @Seb Rupik mentioned (which is answering your question) let's take an example and test it,   Let's say the we have 3 links, and the used method is src-ip, while the src-ip is 10.1.10.38 The bits of the most right octet will be  0 0 1 0 0 1 1 0 And considering that maximum links can be used for ethernet-channel are 8 so we are interested only in the most right 3 bits: 1 1 0 Now, let's assume that you weren't aware of table and you want manually to test what link will be used, you can consider to use all the most right 3 bits, so the answer would be = 6 (for sure it's wrong answer because you know that physically we have only 3 cables) so now, you will need to use the last 2 bits only, so the answer would be = 2, which means the 2nd link will be used!    That's it, the algorithm behavior is logic enough to be tested manually,  Finally, I would like to advice to use the following command to test what link would be used directly from the command line: #test etherhannel load-balance interface port-channel 1 ip 10.1.10.38 and you have to be carefully to choose the load balancing method according to your topology as well as to be careful when you plan your ip addressing, because all are affecting what link would be chosen to carry the data!   I apologize for the prolongation, just wanted to make it clear and simple, i hope it helps, Please don't forget to rate all helpful responses and mark solutions!  Bst Rgds, Andrew Khalil   ...

@eunicemeukieje, Greetings,   Actually, I faced such a problem, and I have searched everywhere! but I wasn't lucky enough to find such an issue solved anywhere, I have found some suggestion from a Cisco Employee through "Cisco Learning Network" website, and he was suggesting Replacing  the switch! as a result, the one who issued that problem replaced it!!!!!!! I couldn't believe that it can happen!    Anyway, and without any more prolongation, I have fixed it, and I would like to share my experience in order to point others to the hardware limitations as well!    The Solution was simply to open the body of the switch itself, and to plug out the console port wire from the switch board, then power the switch on, and again turn it of, and finally plug in the console wire back, when you power the switch, the console input will work prefect!    Note: you can check the disassembly process and procedures photos as attached!    The conclusion, is some time you need to assume some hardware limitations when you pass all the usual software troubleshooting procedures!    Thanks, and wishing to be useful and helpful for those who suffer the same issue, or even to be added as an additional experience to the people who like to learn!    Please don't forget to rate all helpful responses and mark solutions!  It will be so nice from you!

@dm1981 Greetings,  In addition to the reply of @balaji.bandi i would like to add that In you case you should use the off mode, and as a result you will not find any traffic related to the vtp in your network.   Please don’t forget to rate all helpful responses and mark solutions!  Bst Rgds, Andrew Khalil   ...
