    Hello jnet community,

    I have a 6 node EX4600 vitual chassis that was initially installed over 10G SFP+ links while the 40G QSFP+ cables are on the way. Is it possible to switch the VC links without downtime? Would adding the 40g links with "request virtual-chassis vc-port set ..." Configure the VC ports with both 10g and 40g links? I know that the different media will not LAG together into in the VCs.

    These switches are iSCSI so no interruption can occur with connected hosts. I would love to be able to do this live.

    Thanks

    Yes you can, but nothing can guarantee that some interruption won't occur when it comes to making changes to traffic transport paths, especially with something as finicky as iscsi. I would schedule a maintenance window and take the opportunity to upgrade to latest recommended firmware while you're at it if no unplanned disruption is acceptable.

    That was my feeling. Doing this in a maintenance window is sage advice in most cases when dealing with iscsi.

    Thank you smicker
