Figure 226 Typical Master-Local Multi-Controller Deployment
Depends on the need, the administrator can configure the following topology:
Domain Definition
The administrator can define two domains with the following controllers in each domain:
l Domain 1: Local 1 (L1), Master (M), Local 3 (L3)
l Domain 2: Local 2 (L2), M, Local 4 (L4)
To configure an AirGroup domain, see Configuring an AirGroup Domain on page 1052.
Active-Domain Definition
Based on the domain definition, each controller belongs to the following active-domain lists:
l Active-Domain 1: L1, M, L3
l Active-Domain 2: L2, M, L4
To configure an active domain, see Configuring an AirGroup active-domain on page 1053.
AirGroup Controller Communication
Based on the domain and active-domain definitions, the AirGroup controller communication takes place in the
following manner:
l L1, M, and L3 can communicate with each other as they are part of active-domain 1.
l L2, M, and L4 can communicate with each other as they are part of active-domain 2.
l M can communicate with L1, L2, L3, and L4 as M is part of active-domain 1 and 2.
l L1 and L3 cannot communicate with L3 and L4, because they do not have a common active-domain and
they do not share the same VLAN.
AirGroup Server Discovery
l iPad users in L1, M, and L3 can discover any Apple TV or AirPrint Printer in L1, M, and L3.
