Example

Zone AV contains two subzones:

• APAC
• US

Each of these zones contains further subzones. For example:

• APAC contains subzones:
• Beijing
• Malaysia
• Sydney
• US contains subzones:
• Milpitas
• Boston (Boston contains two further subzones: Waltham and Concord).

Leaf zones (the lowest level subzones) contain CNA agents. Figure 2 shows this zone hierarchy.

Figure 2:  Zone hierarchy example

The following configuration commands create this zone hierarchy:

hostname (config-chatter)# zone AV.APAC.Beijing define

hostname (config-chatter-zone)# cna-agent 192.168.1.3

hostname (config-chatter-zone)# cna-agent 192.168.1.2

hostname (config-chatter-zone)# end

hostname (config-chatter)# zone AV.APAC.Malaysia

hostname (config-chatter)# zone AV.APAC.Sydney define

hostname (config-chatter-zone)# cna-agent 192.168.2.2

hostname (config-chatter-zone)# cna-agent 192.168.2.3

hostname (config-chatter-zone)# end

hostname (config-chatter)# zone AV.US.Milpitas define

hostname (config-chatter-zone)# cna-agent 192.168.5.2

hostname (config-chatter-zone)# cna-agent 192.168.5.3

hostname (config-chatter-zone)# cna-agent 192.168.5.4

hostname (config-chatter-zone)# end

hostname (config-chatter)# zone AV.US.Boston.Waltham define

hostname (config-chatter-zone)# cna-agent 192.168.3.3

hostname (config-chatter-zone)# cna-agent 192.168.3.4

hostname (config-chatter-zone)# end

hostname (config-chatter)# zone AV.US.Boston.Concord

hostname (config-chatter-zone)# cna-agent 192.168.4.3

hostname (config-chatter-zone)# cna-agent 192.168.4.2

hostname (config-chatter-zone)# end
