Adding interface to multiple VLANs in trunk mode. Before enabling trunk mode the port encapsulation must be set to dot1q<\/mark>. Below configuration will allow all VLANs on the switch. <\/p>\n\n\n\n

If a set of only specific VLANs need to be allowed on that port the below configuration is needed. This will allow only VLANs 172 and 254, all other VLANs that are configured on the switch will not be available through that port.<\/p>\n\n\n\n

On a trunk configured port, a VLAN can be configured in an access mode, if that is needed.<\/p>\n\n\n\n

If multiple interfaces need to be configured in the same way, a range <\/mark>can be used.<\/p>\n\n\n\n
