What name is given to a vlan on an ieee 802.1q trunk whose frames are not tagged?

The name given to a VLAN on an IEEE 802.1Q trunk whose frames are not tagged is the "native VLAN." The native VLAN is used for untagged traffic on a trunk link, allowing devices that do not support VLAN tagging to communicate over the trunk. By default, VLAN 1 is designated as the native VLAN, but this can be changed to another VLAN as needed.


Why would packets from the router or hosts fail when trying to reach the switch management interfaces if the native VLAN were left in default?

The native VLAN is untagged. If the VLAN 99 traffic to the router is untagged (as it would be, because that is native on the switches), the router cannot interpret the data because there is no VLAN information in the header as expected. In turn, the router tags all VLAN 99 traffic outbound, and leaves VLAN 1 data untagged, so the switches are unable to correctly interpret either. VLAN traffic to the other VLANs should not be affected by the assignment of the native VLAN.

What is the purpose of the switch command switch port access vlan 99?

the switchport access vlan 99 command is used to designate a specific VLAN for a switch port, allowing you to control how traffic on that port is treated and segregated from traffic on other ports and VLANs in the network. This is a fundamental configuration step in building and managing VLANs within a network infrastructure.
