WESM zl Management and Configuration Guide Supplement 2007-09

zl Switch Features Not Supported

As the Module uses internal ports and VLANs for wireless services to stations,

not all of the features of the zl switch are applicable. For example, adding the

internal downlink or uplink port to a trunk would not be compatible with the

Module’s operation, and is prohibited.

Some zl switch configurations are not allowed by the Command Line Interface

(CLI). When a CLI command fails, a descriptive message is typically displayed.

Warning messages are issued when an operation could potentially cause

problems managing traffic through the Module. For example, if the Module’s

downlink and uplink ports are configured as tagged members of the same

VLAN, a warning message is issued because this is not a recommended

configuration. In some cases, Log messages are created stemming from an

operation or event, and describe potential problems that may occur as a result.

Note zl switch ports that are not used by the Wireless Edge Services Module

continue to operate as regular zl switch ports. Their operation is not affected.

Table 2

presents the zl switch features that are not supported for use with a

Wireless Edge Services Module.
