MSM7xx Controllers Configuration Guide v6.4.0

Terms used in the tables
• Egress network in VSC binding: This column refers to the Egress network option that can be
configured when an AP group is bound to a VSC. The egress network can be used to assign
a specific VLAN. How this VLAN is applied to the routing of traffic is illustrated by the tables.
• Client data tunnel: The client data tunnel can be used by an AP to transport wireless user traffic
to the controller. The client data tunnel is automatically used if the network path between an
AP and the controller traverses a router. In the case where the AP is on the same layer 2 subnet
as the controller, the client data tunnel is not automatically used, but can be manually activated
by enabling the Always tunnel client traffic option on the VSC configuration page. Available
on access-controlled VSCs only.
• User-assigned VLAN is not assigned via RADIUS or local user accounts: This column indicates
what happens when a user-assigned VLAN attribute is not assigned via RADIUS or via a local
user account or account profile.
• User-assigned VLAN exists in the mobility domain: This column indicates what happens when
a user-assigned VLAN attribute is assigned via RADIUS or via a local user account or account
profile, and if that VLAN (or network) is defined within the mobility domain. In some cases
the behavior is different if the VLAN attribute specifies a network profile name or an actual
VLAN ID (number).
• User-assigned VLAN does not exist in the mobility domain: This column indicates what happens
when a user-assigned VLAN attribute is assigned via RADIUS or via a local user account or
account profile, and if that VLAN (or network) is not defined within the mobility domain. In
some cases the behavior is different if the VLAN attribute specifies a network profile name or
an actual VLAN ID (number).
Traffic flow examples
The following examples illustrate some typical VLAN scenarios using the information from the tables
in section “Traffic flow for wireless users” (page 221).
To help cross-reference with the tables, all configuration settings are shown using the headings
and descriptions from the tables.
