IAP and vlan pooling question

Hi all, a question re IAP cluster and vlan pooling.


If I have a cluster of IAP 105's, 3 distinct SSI'ds each with a static vlan assigned, for instance


vlan 100 guest

vlan 200 staff

vlan 300 apple


if i use vlan pooling for each ssid as recommended, does this mean a wireless client when connecting drops into either of these 3 vlans at random and therefore picks up a dhcp address in that vlan ?




Re: IAP and vlan pooling question

That is correct. If you use pooling, the client could be in any vlan in the pool


The "randomness" is based upon a hash of the client mac if memory serves me correctly.


Kudos appreciated, but I'm not hunting! (ACMX 104)

Re: IAP and vlan pooling question

Thanks, thats great, one other q if anyone can help, enabling airplay globally would negate necesarily using a specific Apple SSID ?


Would this affect enabling multicast ARP ?




Re: IAP and vlan pooling question

I think the answer you're looking for is yes, it probably does negate it.


BUT, that's me making an assumption that the reason you had a specific apple VLAN in the first place, was due to challenges with bonjour/mdns etc (apple "multicast" stuff) when traversing vlans?


If that was the reason, the answer's yes. If there were other reasons the apple stuff was on a specific VLAN, they might still be relevant?


I think your second question is related to dropping bcast/mcast and converting ARP to unicast? If so, my understanding is Airgroup works along side this (when enabled) just fine.
