Final answer:
The Profile Name in the WLC GUI is used internally to identify different WLAN profiles, whereas the SSID is the name visible to clients. The SSID can be different from the Profile Name and should be chosen carefully to ensure uniqueness and security. It can be identical to the Profile Name if desired, but that's a choice based on the network administrator's preferences and company policy.
Step-by-step explanation:
When configuring a Wireless Local Area Network (WLAN) through a Wireless LAN Controller (WLC) Graphical User Interface (GUI), the Profile Name is different from the SSID. The Profile Name is used internally within the WLC to identify different WLAN profiles, whereas the Service Set Identifier (SSID) is the network name that clients see and connect to. While configuring the WLAN, it is essential to properly configure the SSID to ensure clients can identify and connect to the correct network.
The statement regarding the SSID not being configured with the Profile Name "MyCompanyLAN" is a matter of convention rather than a hard rule. Typically, the SSID can be set to any value that suits the network administrator's preferences and follows the organization's naming conventions. However, this value should be unique within the local broadcast domain to avoid confusion with other nearby networks. The chosen SSID will be the identifier that the end-users see when they are scanning for wireless networks available to connect to.
In practice, while the SSID and Profile Name can indeed have the same value, careful consideration should be given to the network's operational context and the naming standards adopted by the organization. Since SSID is publicly broadcasted, some companies prefer not to use an easily associateable name with the business for security reasons. Therefore, the SSID could be more generic or cryptic to provide less direct information to potential outside observers.
