AP 635 - Do we etherchannel?

    Hi all - with the 600 series APs we're looking to utilise both ethernet ports. Are there any thoughts about etherchannel connections etc?

    First, we don't use Etherchannel but rather create the LAG using LACP or you can utilize the active/standby functionality.

    In general the effort for provisioning the LAGs doesn't provide enough benefit to be worthwhile, and active/standby will meet the usual redundancy requirements while also not requiring a single logical switch.

    No,

    There will be no performance impact for clients.

    (There is no need for LAG in any Aruba dual eth. AP's)

    Why would there be no benefit to the clients?  It would seem obvious that dispatching packets balanced across the two eth0/1 should improve throughput. Or is the default LACP not set up that way? How can we configure the AP's LACP to negotiate load balancing with the switch?  (The documentation I have been able to find on this is pretty obtuse.)

    Caveat: if the AP is tunneling client traffic back tot he controller, then LACP would see the tunnel as the one & only session, which would NOT be balanced across LAG member links. But if not tunneling ... ?

    I have numerus post on the topic in the forum, there is no proven experience at all 

    (for aggregated benefit, as you suggest], 

    Just plug in the two cables, and work with that :) [all other consideration set aside]
