You are configuring Ethernet Ring Protection Switching (ERPS) on an ArubaOS-CX switch. Is this a guideline for configuring timers?

Solution: The guard interval is set in units of 10 ms and should exceed the maximum expected delay for forwarding a frame around the complete ring.

Refer to the exhibit.

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: 51 protected VLANs: 51-100 Ring 1, Instance 2:

control VLAN: 51 protected VLANs: 101-150 Ring 2, Instance 1: control VLAN: 181 protected VLANs:

181-200 Ring 2, Instance 2: control VLAN: 181 protected VLANs: 201-220

Is this correct positioning of AtubaOS-CX switches in the data center?

Solution: A data center will use a leaf-spine topology and requires 64 leaf switches. Aruba CX 8325 switches can be a good choice for both the leaf and spine switches.

An ArubaOS-CX is \ssmq DCBX on Interface 1/1/1. You enter this command:

show dcbx interface 1/1/1

Is this where you can see whether the connected converged network adapter (CNA) has accepted the application priorities advertised with DCBX?

Solution: in the Application Priority Map Local advertisement section

Is this how you should position switches in the ArubaOS-CX portfolio for data center networks?

Solution: Deploy Aruba 8400 switches as data center leaf switches.

Does this correctly describe how the Virtual Switching Extension (VSX) fabric reacts to various component failure scenarios?

Solution: The ISL goes down, and after a few seconds, the keepalive link goes down too. Switch-1 and Switch-2 remains up.

The Split-recovery mode is enabled. In this case the secondary switch first shutdowns and then enables SVis.

A data center has a three-tier topology with ArubaOS-CX switches at each layer, is this a use case for implementing Virtual Switching Extension (VSX) at the core?

Solution: The customer wants to deploy a single control plane for the core fabric.

Refer to the exhibit.

You are adding a VLAN 30, subnet 10.0.30.0/24 to the network shown in the exhibit. (This network is simplified to just the relevant switches for this item.) This subnet belongs in VRF A, and you have added a Layer 3 VLAN 30 interface attached to this VRF on Switch-1. You want to make the services in this VLAN available to devices in 10.1.20.0/24 in VRF B.

Is this part of a valid setup for meeting these requirements?

Solution: Add VRF B as the secondary VRF on VLAN interface 30.
