Limit bandwith on 2 interfaces
Good morning Srs,
My scenario is as follows, I have ten pairs of servers connected in a DELL N1548. I would like to configure that each server pair does not exceed 1GB speed, taking into account that each pair of servers use 2 interfaces.
I know I could put 500Mbps for each card, however I need to do it dynamically so that when 1 server is only traveling it can reach 1Gbps and when the 2 are traveling does not exceed 1Gbps. I have VLANs on all the server pairs.
I have tried to create a port-channel and limit it, but I lost the communication with the hosts, I believe it is normal because when creating a port-channel is generated 1 new MAC address and can not segment it to 2 servers, it would have to be connected with only 1.
What would be the best way to do this? ACLs? Limit the speed of the VLAN? Awaiting.
Anyway, thank yours

Hi,
Page 682 https://downloads.dell.com/manuals/common/n-series_cli_660_en-us.pdf Diffserv is probably the best option for doing this, but is somewhat feature limited on the N1548. I am assuming you have one 10Gb uplink and that is why you are trying to limit the bandwidth from 20 to 10. Are you having issues with latency under load?

Exactly that, I have a 10Gb uplink. In the meantime I am expanding this network and I will probably reach 15 pairs of servers. I currently have 2 times of the day I use the 10Gb of uplink and I have already verified that I have pairs of servers using 2Gb.
I use this network for backup, so latency is not one of my biggest problems, but rather it harms a couple of servers that could be using 1Gb at that time but is only using 20 ~ 30Mb.
I wll see the documentation and reply soon
