I have 2 ISR4431, and I configured LACP which includes 2 links. So far This is just at test level.
I configured LACP, and total bandwidth reached 2 GB. Now I need to allocate this total bandwidth for different purposes such as 128Kb for Service1 and 500Kb for Service 2 etc. So that what technique do you guys recommend me? And how to test it? Thank you.
I am not sure the ISR 4431 and your current IOS version support QoS for EtherChannel interfaces. Try if your router takes the global command below, which is required for this feature to work:
port-channel load-balancing vlan-manual
The document below has several sample configs:
Configuration Examples for QoS for Etherchannels
I look through these examples, and I think it suits my situation. But I am still confusing.
There will be 2 ISR at the 2 ends, and 2 links between them. I will aggregate these 2 links, and increase the bandwidth. After that, I am going to configure QoS on the port-channel interface.
ISR1 < =========== > ISR2
The question is should I configure QoS only on one ISR or on Both of them?
