Refer to the exhibit.Network Faceplates have not been installed on the HMI and so you need to map a network based on information available from RSLinx. Which most accurately represents the network configuration?A )B )C )D )
Which CLI command will display IGMP snooping information in a Cisco IE2000 or Stratix 5700 switch?
Refer to the exhibit.The control system depicted in the exhibit uses VLAN 300 for all of its device ports and PVST is enabled on each switch to switch connection. L2SW4 was inserted between L2SW3 and L2SW5. Links FO2 and FO3 were added and FO1 was disconnected.Prior to the installation of L2SW4, PanelView was able to communicate with PLC#1. After the change, PLC#1 and PanelView are still able to communicate but neither PLC#1 or PanelView are able to communicate with I/O #1.L2SW4# show run interfaces FastEthernet 1/1description I/O#1switchport access vlan 300switchport mode accessspanning-tree portfastspanning-tree bpduguard enableL2SW4# show interfaces trunk -Port Mode Encapsulation Status Native vlanGi1/1 on 802.1q trunking 1Gi1/2 on 802.1q trunking 1 Port Vlans allowed on trunkGi1/1 1,3-9, 301-305,400 Gi1/2 1,3-9, 301-305,400 Port Vlans allowed and active in management domainGi1/1 1,3-9, 301-305,400 Gi1/2 1,3-9, 301-305,400 Port Vlans in spanning tree forwarding state and not prunedGi1/1 1,3-9, 301-305,400 Gi1/2Based on the output from the switch, what is preventing I/O#1 from communicating with PLC#1 and PanelView?
Refer to the exhibit.L3SW1 has a spanning-tree priority of 8192 set on VLANs 1, 300, and 301, and these VLANs are configured on and trunked between all switches. Executing the command show spanning-tree blockedports on L2SW5 results in:L2SW5# show spanning-tree blockedportsName Blocked Interfaces List-------------------- ------------------------------------VLAN0001 Gi1/1 -VLAN0300 Gi1/1 -VLAN0301 Gi1/1 -An additional VLAN, VLAN302, is defined on all switches and trunked between them. VLAN302 access ports are set up on each of the switches and PLC#1, I/O#1, and the PanelView are attached. You expect the new VLAN to be listed as blocked on interface GigabitEthernet1/1 of L2SW5 but it is not. The three new devices are able to communicate with each other.After executing the same command on all switches you see this output on L2SW4:L2SW4# show spanning-tree blockedportsName Blocked Interfaces List-------------------- ------------------------------------VLAN0001 Gi1/2 -VLAN0300 Gi1/2 -VLAN0301 Gi1/2 -Why is VLAN302 forwarding on L2SW5 interface GigabitEthernet 1/1 and L2SW4 interface GigabitEthernet 1/1 and 1/2?
Refer to the exhibit.All of the vlans listed in the routing table below are trunked using 802.1q and are active on all switches. PLC1, PLC2, and PLC3 each has IP address192.168.0.1/24 and are connected to ports configured for vlan 50. L2SW1, L2SW2, and L2SW3 are not using vlan trunking for vlan 50.L3SW1 has following routing table:10.0.0.0/8 is variably subnetted, 12 subnets, 2 masksC 10.3.138.0/23 is directly connected, Vlan307C 10.3.136.0/23 is directly connected, Vlan306C 10.15.153.0/24 is directly connected, Vlan398C 10.3.142.0/23 is directly connected, Vlan309C 10.3.140.0/23 is directly connected, Vlan308C 10.3.186.0/23 is directly connected, Vlan293C 10.15.154.0/24 is directly connected, Vlan399C 10.3.184.0/23 is directly connected, Vlan292C 10.3.190.0/23 is directly connected, Vlan295C 10.3.188.0/23 is directly connected, Vlan294C 10.3.182.0/23 is directly connected, Vlan291C 10.3.180.0/23 is directly connected, Vlan290PLC1, PLC2, and PLC3 cannot be reconfigured. What can be done to be able to simultaneously communicate with PLC1, PLC2, and PLC3?
Refer to the exhibit.SW1, SW2 and virtual switch are connected in a loop. SW1 and SW2 are standard layer-2 switches. Which loop prevention mechanism is best suited for use within this topology?
