116 CHAPTER 13: I SOLATE-USER-VLAN CONFIGURATIONc CAUTION: When you use the port hybrid pvid vlan command to configure thedefault VLAN ID for a port, you need to specify the vlan-id as a secondary VLANfor a downlink port and specify the vlan-id an isolate-user-VLAN for an uplink port.Configuring Mappingbetweenisolate-user-VLAN andSecondary VLANYou can use the following command to establish the mapping relationshipbetween an isolate-user-VLAN and a secondary VLAN.c CAUTION: An isolate-user-VLAN can establish mapping relationship with multiplesecondary VLANs, however, a secondary VLAN can establish mapping relationshipwith only one isolate-user-VLAN.DisplayingIsolate-User-VLANConfigurationAfter the above configurations, you can execute the display command in any viewto view the running status of the isolate-user-VLAN and verify the configurationeffect.Isolate-User-VLANConfigurationExampleNetwork requirements■ Switch A connects with Switch B and Switch C. Packets from Switch B andSwitch C to Switch A are without VLAN tag, so that Switch A needs not toconsider the VLAN configurations of the lower layer switches.■ VLAN 5 on Switch B is an isolate-user-VLAN which includes the uplink portEthernet2/0/1 and two secondary VLANs: VLAN 2 and VLAN 3. VLAN 3includes port Ethernet2/0/2, and VLAN 2 includes port Ethernet2/0/5.■ VLAN 6 on Switch C is an isolate-user-VLAN which includes the uplink portEthernet2/0/1 and two secondary VLANs: VLAN 3 and VLAN 4. VLAN 3includes port Ethernet2/0/3, and VLAN 4 includes port Ethernet2/0/4.Add a port to theisolate-user-VLAN and thesecondary VLANport hybrid vlan vlan-iduntaggedRequiredConfigure the default VLANID of a portport hybrid pvid vlanvlan-idRequiredTable 65 Add ports to isolate-user-VLAN and secondary VLAN and configure the ports tountagged packetsOperation Command DescriptionTable 66 Configure isolate-user-VLAN-to-secondary VLAN mappingOperation Command DescriptionEnter system view system-view -Configure the mappingrelationship between anisolate-user-VLAN and asecondary VLANisolate-user-vlan vlan-idsecondary vlan-listRequiredTable 67 Display isolate-user-VLAN configurationOperation Command DescriptionDisplay the mappingrelationship between theisolate-user-VLAN and thesecondary VLANdisplay isolate-user-vlan[ vlan-id ]The display command can beexecuted in any view.
