In the switching network as shown in the figure, VLAN10 is set as Isolate-user-vlan on switch SWA, VLAN2 and VLAN3 are set as Secondary VLAN of VLAN 10; VLAN2-VLAN20 is created on switch SWB, and VLAN20 is set as Isolate-user-vlan , VLAN4 is the Secondary VLAN of VLAN20. After setting the IP address of each device as shown in the figure, the following statement is correct (choose one or more)
In the switching network as shown in the figure, VLAN10 is set as Isolate-user-vlan on switch SWA, VLAN2 and VLAN3 are set as Secondary VLAN of VLAN 10; VLAN2-VLAN20 is created on switch SWB, and VLAN20 is set as Isolate-user-vlan , VLAN4 is the Secondary VLAN of VLAN20. After setting...
In the switching network as shown in the figure, VLAN10 is set as Super VLAN on switch SWA, VLAN2 and VLAN3 are Sub VLAN of VLAN10, port Ethernet1/0/3 is Trunk port, PVID is VLAN1, allowing all VLANs to pass through; Create VLAN2~VLAN20 on SWB, port Ethernet1/0/4 as Trunk port, PVID is VLAN1, allowing all VLANs to view Ethernet 1/0/3 port information on SWA, the correct one is displayed below
In the switching network as shown in the figure, VLAN10 is set as Super VLAN on switch SWA, VLAN2 and VLAN3 are Sub VLAN of VLAN10, port Ethernet1/0/3 is Trunk port, PVID is VLAN1, allowing all VLANs to pass through; Create VLAN2~VLAN20 on SWB, port Ethernet1/0/4 as Trunk port, PVID...
In the switching network shown in the figure, VLAN10 is set as Isolate-user-vlan on the switch SWA, VLAN2 and VLAN3 are set as the Secondary VLAN of VLAN 10; VLAN2? VLAN20 is created on the switch SWB, and VLAN20 is set as Isolate-user-vlan , VLAN4 is VLAN20 Secondary VLA after setting the IP address of each device as shown in the figure, the local proxy ARP function is enabled on both SWA and SWB. At first, the switch and pc did not learn their corresponding ARP entries in PCA. During the process of pinging PCB, PCA will send an ARP request. The source MAC address of the ARP request packet forwarded by the switch to PCB is
