AP650 redundant links or aggregate

jason_simmons — Wed, 07 Aug 2019 04:17:00 GMT

Both Ethernet interfaces on our AP650's are connected to multi-gig switchports. Knowing that only ETH0 is capable of 2.5G, should I configure the interfaces as an aggregate or redundant?

How should I configure the switchports for each mode?

There are very few use cases were aggregating the ports on an AP will come in handy, generally this won't be needed. I'd recommend going with redundant instead. The switch ports will need to be set as trunk ports if you're using more than one VLAN, or access ports if we're only using one VLAN.

The problem I'm facing is that some of the APs aren't coming up until I unplug one of the links to the AP.

Currently, the switch ports are configured as a trunk and all VLANs are being tagged. The ports on the AP were configured as uplinks before I reconfigured them as redundant links.

I rebooted the switch after configuring the AP ports as redundant links and the issue remains only 4 of the 12 APs connected to this switch came up after the reboot.

I just rebooted after disabling one link to each AP and now none of them are online.

Could you confirm the power budget on the switch you are using? Also what switch model are we using?

It’s a VC stack of Juniper EX4300-MPs. PoE budget is 1100W.

Thank you for that information. Are these APs the only devices connected to that switch? Also could you send me tech data from one of the APs? There are a few things I'd like to check in that data. This guide reviews how to get tech data from the CLI of the AP: https://thehivecommunity.aerohive.com/s/article/Collecting-Tech-Data-via-CLI

Sorry for the delayed response. I think this is a switch, configured as a virtual chassis issue and not the AP, but I attached the tech data you wanted. Here's what I've discovered.

I ran all these test on the multi-gig ports on the switch except for the last one. I also connected both ports on an AP630 to the multi-gig ports and it worked as expected.

No VC + default config + Eth0 = pass

No VC + default config + Eth0 & Eth1 = pass

No VC + basic config + Eth0 = pass

No VC + basic config + Eth0 & Eth1 = pass

VC + default config + Eth0 = pass

VC + default config + Eth0 & Eth1 = fail

VC + default config + Eth0 & Eth1 on gig switchports = fail

Thank you for your patience, I reviewed the data with our experts and they asked that we open a technical support case to move forward with this issue.
