To create a VLAN, an Ethernet switch can be configured to group ports into numbered VLANs. For example, when packets arrive on port #9 (VLAN #1), the switch can push those packets through all other ports belonging to VLAN #1, and only those ports. This simple, static approach is known as port-based VLAN.
Business casual is an ambiguously-defined dress code that has been adopted by many professional and white-collar workplaces in Western countries. It entails neat yet informal attire and is generally more casual than informal business attire but more formal than casual or smart casual attire.
In cool weather, you can add a blazer or sweater. Women's business casual choices range from dress pants or a knee-length or longer skirt and a blouse to a dress that comes at least to the knee. Appropriate shoes include sling-backs, flats and boots, but you should avoid flip-flops and tennis shoes.
