With my Aps set to DHCP the Aps are asking for a dhcp address on every vlan that is being scanned. Is it possible to scan with out each ap having to get an IP on each vlan? This is primarily for printing if the type could be changed to assist.

This is referring to the Bonjour gateway. I am sorry I did not include that.

This would be expected, the APs need to have an IP address on any VLAN that they need to host the Bonjour service for. Otherwise they won't be able to advertise the service on that VLAN.

Darrell,

If you think about what it is doing, it makes sense. Bonjour is Apples version of mDNS. DNS is IP. IP shows up in layer 3 of the OSI model. So the AP acting as the bonjour listener (BDD in Aerohive's terms) would have to have Layer 3 (IP) access to each VLAN to be able to redistribute the traffic from one VLAN to another.

Thank you for the clarification. Is it possible to find what the Mac address would be on the Vlans? I would prefer to make reservations.

Yeah. So it should be the ethernet address of the AP acting as the BDD. I don't believe it augments that MAC any per VLAN. But if you SSH into one AP (unless you know which AP is acting as your BDD then SSH into it).

If not the BDD run this command:

show bonjour status

Look for "My BDD: <IP>"

Then SSH into that BDD IP. This is the IP of the AP that will have the interfaces on the VLANs. Once in that AP, do a:

show interface

This will show you the interface(s) that exist on the AP. If you see eth0, eth0.1, eth0.2, etc., then it does create sub interfaces for each VLAN and you'd need to reserve a unique MAC per VLAN.

Note you probably want to set priority for this AP to always be your BDD if you reserve IP for it in your DHCP scope. You can edit the AP individually and adjust it's BDD priority value under Optional Settings and Bonjour Gateway Configuration (HM Classic). Higher number takes precedence I believe.

Brian Thank you for the assistance. I am new to Aero Hive. It appears that all of my APs are requesting DHCP from the pool in each vlan. From reading your response, should and is there a way to configure so that only one will act as the BDD?

Hmm. That's a bit of a different scenario. As only one AP should be the "go between" for bonjour gateway and the VLANs. When you say "all", do you actually mean all? Or a large subset but not all?

Since all of like model APs get the same priority value, they base it off of either lowest/highest MAC, so even then only one should have done this. Unless you implemented the APs in stages and as new APs came online, they decided based off of their MAC to take over the BDD roles.

If you SSH into one AP and do a show bonjour status command, does it show a "My BDD with an IP that is another AP?

If you do a show bonjour vlan do you see IPs tied to VLANs as well?

Brian -

I must have been mistaken or raising the priority on the AP I wanted to use for BDD did the trick.

I am only seeing the one AP getting an address from the vlan DHCP Pools. Thank you for your time and sorry for any confusion I caused.

No worries. Glad it all helped.
