WESM zl Management and Configuration Guide Supplement 2007-09

13
Using zl Switch Features for the Module
Radio ports connected to infrastructure switches also can use the Auto-VLAN,
but the infrastructure switches require manual configuration of the
Auto-VLAN and port membership assignments. This includes the downlink
radio ports (unless 802.1X RADIUS-assigned VLANs do so) and network
uplink ports to the wireless services-enabled switch.
To simplify manual configuration, it is recommended that any infrastructure
switches be members of a management VLAN that includes the wireless
services-enabled zl switch.
The lldp auto-provision radio-ports command enables or disables auto-
provisioning by the switch (enabled by default). The action taken by the switch
when a Module or radio port is detected or removed depends on the state of
auto-provisioning (enabled or disabled) and the existence and port
membership of the Auto-VLAN. This behavior is described in Table 1
.
Note In the table, the state Auto-Provision means auto-provisioning is enabled;
No Auto-Provision means auto-provisioning is disabled.
Auto-VLAN means an Auto-VLAN is configured on the switch; No Auto-VLAN
means that there is no Auto-VLAN configured.
