What two configurations are necessary to remotely access a switch?

To remotely access a switch, the essential configurations involve having an appropriate VLAN assignment along with a specified Default Gateway.

When a switch is configured to operate over a network that includes devices across different subnets, it is necessary to designate a Default Gateway. This Default Gateway serves as the means for the switch to communicate with devices that are not located within its local subnet, thus enabling remote access. Moreover, the switch must be configured to operate on a VLAN, which establishes the logical segmentation of the network. Usually, VLAN 1 is often used as the management VLAN where default settings apply, allowing administrative access to the switch.

In sum, having both the VLAN configuration and the Default Gateway setup ensures that the switch can be reachable remotely by management stations that may exist in other network segments.
