    I heard that IBM says that when using SAN extension for FICON, it´s necessary to have two FCIPs bundle into one port-channel, is that correct?

  2. Caio Oliveira says:

    So in the CCIE lab do you recommend to bundle FCIP interfaces on a port-channel to follow the best practice or not?
    Like this, imagine a question like this in the exam:
    – Traffic from FICON VSAN should use san-extension link (imagine that you have 2 fcips pre-configured in older tasks). My question is: create a port-channel for this 2 fcips or use this 2 fcips as separated links or ask the proctor 🙂 ?

      It depends how it is worded. If they wanted it done a certain way then their will be key words, you have to read the questions carefully. And you have nothing to lose I something is not clear and you ask the proctor, that’s why they are there.
