which shows the topology tot an Ethernet Ring Protection Switching (ERPS) solution.

Is this a valid design for the control and protected VLANs on the VSX fabric 1 switches?

Solution: Ring 1, instance 1:

control VLAN: 1000protected VLANs: 51-135 Ring l,Instance2:

control VLAN: 1001 protected VLANs: 136-220 Ring 2, Instance 1: control VLAN: 1000 protected VLANs: 181 -200 Ring 2, Instance 2: control VLAN: 1003 protected VLANs: 201 -220

  1. Yes
  2. No

Answer(s): B

Explanation:

Ring 1, instance 1: control VLAN: 1000protected VLANs: 51-135 Ring l,Instance2: control VLAN: 1001 protected VLANs: 136-220 Ring 2, Instance 1: control VLAN: 1000 protected VLANs: 181 -200 Ring 2, Instance 2: control VLAN: 1003 protected VLANs: 201 -220 is not a valid design for the control and protected VLANs on the VSX fabric 1 switches for an Ethernet Ring Protection Switching (ERPS) solution. The control VLANs must be unique for each ring instance and must not overlap with any protected VLANs. In this design, the control VLAN 1000 is used for both ring 1 instance 1 and ring 2 instance 1, which can cause conflicts and errors. Also, the protected VLANs 181-220 are used for both ring instances on ring 2, which can cause loops and traffic duplication2.

Is this a valid design for the control and protected VLANs on the VSX fabric 1 switches?

Solution: Ring l, instance 1:

control VLAN: 1000 protected VLANs: 51-135 Ring 1, Instance 2:

control VLAN: 1000 protected VLANs: 136-220 Ring 2, Instance 1: control VLAN: 1001 protected VLANs: 181 -200 Ring 2, Instance 2: control VLAN: 1001 protected VLANs: 201 -220

  1. Yes
  2. No

Answer(s): A

Explanation:

Ring l, instance 1: control VLAN: 1000 protected VLANs: 51-135 Ring l,Instance2: control VLAN: 1001 protected VLANs: 136-220 Ring 2, Instance l: control VLAN: 1002 protected VLANs: l8l -200 Ring 2, Instance2: control VLAN: l003 protected VLANs:201 -220 is a valid design for the control and protected VLANs on the VSX fabric l switches for an Ethernet Ring Protection Switching (ERPS) solution. The control VLANs are unique for each ring instance and do not overlap with any protected VLANs. The protected VLANs are also unique for each ring instance and do not overlap with any control VLANs2.



You enter this command on an ArubaOS-CX switch:

Switch# show erps status ring 1

Is this what the specified status means?

Solution: The status is Protection, which means that the ring is up and fully connected with the RPL port blocked.

  1. Yes
  2. No

Answer(s): A

Explanation:

The status is Protection, which means that the ring is up and fully connected with the RPL port blocked is what the specified status means for Ethernet Ring Protection Switching (ERPS) on an

ArubaOS-CX switch. Protection is one of the possible statuses for an ERPS ring instance, and it indicates that the ring is operating normally with one port blocked to prevent loops. The RPL port is the port that connects to the RPL node, which is responsible for blocking and unblocking traffic on the ring2



You enter this command on an ArubaOS-CX switch:

Switch# show erps status ring 1

Is this what the specified status means?

Solution: The status is Idle, which means that the ring is up and fully connected with the RPL port blocked.

  1. Yes
  2. No

Answer(s): B

Explanation:

The status is Idle, which means that the ring is up and fully connected with the RPL port blocked is not what the specified status means for Ethernet Ring Protection Switching (ERPS) on an ArubaOS-CX switch. Idle is one of the possible statuses for an ERPS ring instance, but it indicates that the ring is not operational and no port is blocked. This can happen when the ring is not configured properly or when there is a miscommunication between the nodes1.
