The switch itself does not support this setting! In fact, adding VLANs is rarely used. Routes need loops to communicate with each other. The loops in different segments of each VLAN can distinguish the direction of VLAN. If the target is a server, filter out other VLANs directly on the trunk link! \x0d\ Configuration of Layer 1 and Layer 3 switches \ x0d \ Ruijie & gt enabled-> Enter privileged mode \ x0d \ Ruijie # configterminal-> Enter global configuration mode \ x0d \ SDK _1(config) # hostnamecd12371-> The name of the configuration switch is SDK _1\ x0d \ SDK.
