To configure traffic replication to the monitoring software for your Tampa web overlay segments with bi-directional traffic, you need to follow these steps:

• Log in to the NSX Manager UI with admin credentials. The default URL is https://.
• Navigate to Networking > Segments and select the Tampa web overlay segment that you want to replicate the traffic from. For example, select Web-01 segment that you created in Task 2.
• Click Port Mirroring > Set > Add Session and enter a name and an optional description for the port mirroring session. For example, enter Tampa-Web-Monitoring.
• In the Direction section, select Bi-directional as the direction from the drop-down menu. This will replicate both ingress and egress traffic from the source to the destination.
• In the Source section, click Set and select the VMs or logical ports that you want to use as the source of the traffic. For example, select Web-VM-01 and Web-VM-02 as the source VMs. Click Apply.
• In the Destination section, click Set and select Remote L3 SPAN as the destination type from the drop-down menu. This will allow you to replicate the traffic to a remote destination outside of the NSX-T environment.
• Enter the IP address of the destination device where you have installed the network monitoring software, such as 10.10.10.200.
• Select an existing service profile from the drop-down menu or create a new one by clicking New Service Profile. A service profile defines the encapsulation type and other parameters for the replicated traffic.
• Optionally, you can configure advanced settings such as TCP/IP stack, snap length, etc., for the port mirroring session.
• Click Save and then Close to create the port mirroring session.

You have successfully configured traffic replication to the monitoring software for your Tampa web overlay segments with bi-directional traffic using NSX-T Manager UI.

To troubleshoot why the Tampa web servers cannot communicate to any northbound networks, you need to follow these steps:

• Log in to the NSX Manager UI with admin credentials. The default URL is https://.
• Navigate to Networking > Tier-0 Gateway and select the tier-0 gateway that connects the NSX-T network segment to the northbound networks. For example, select T0-GW-01.
• Click Interfaces > Set and verify the configuration details of the interfaces. Check for any discrepancies or errors in the parameters such as IP address, subnet mask, MTU, etc.
• If you find any configuration errors, click Edit and modify the parameters accordingly. Click Save to apply the changes.
• If you do not find any configuration errors, check the connectivity and firewall rules between the tier-0 gateway and the northbound networks. You can use ping or traceroute commands from the NSX Edge CLI or the vSphere Web Client to test the connectivity. You can also use show service router command to check the status of the routing service on the NSX Edge.
• If you find any connectivity or firewall issues, resolve them by adjusting the network settings or firewall rules on the NSX Edge or the northbound devices.
• After resolving the issues, verify that the Tampa web servers can communicate to any northbound networks by pinging the Control Center @ 192.168.110.10 from one of the web servers.

To create a logical load balancer for several web servers, you need to follow these steps:

• Log in to the NSX Manager UI with admin credentials. The default URL is https://.
• Navigate to Networking > Load Balancing > Load Balancers and click Add Load Balancer.
• Enter a name and an optional description for the load balancer. Select the tier-1 gateway where you want to attach the load balancer from the drop-down menu or create a new one by clicking New Tier-1 Gateway. Click Save.
• Navigate to Networking > Load Balancing > Application Profiles and click Add Application Profile.
• Enter a name and an optional description for the application profile. Select HTTP as the application type from the drop-down menu. Optionally, you can configure advanced settings such as persistence, X-Forwarded-For, SSL offloading, etc., for the application profile. Click Save.
• Navigate to Networking > Load Balancing > Monitors and click Add Monitor.
• Enter a name and an optional description for the monitor. Select HTTP as the protocol from the drop-down menu. Optionally, you can configure advanced settings such as interval, timeout, fall count, rise count, etc., for the monitor. Click Save.
• Navigate to Networking > Load Balancing > Server Pools and click Add Server Pool.
• Enter a name and an optional description for the server pool. Select an existing application profile from the drop-down menu or create a new one by clicking New Application Profile. Select an existing monitor from the drop-down menu or create a new one by clicking New Monitor. Optionally, you can configure advanced settings such as algorithm, SNAT translation mode, TCP multiplexing, etc., for the server pool. Click Save.
• Click Members > Set > Add Member and enter the IP address and port number of each web server that you want to add to the server pool. For example, enter 192.168.10.10:80 and 192.168.10.11:80 for two web servers listening on port 80. Click Save and then Close.
• Navigate to Networking > Load Balancing > Virtual Servers and click Add Virtual Server.
• Enter a name and an optional description for the virtual server. Enter the IP address and port number of the virtual server that will receive the client requests, such as 10.10.10.100:80. Select HTTP as the service profile from the drop-down menu or create a new one by clicking New Service Profile. Select an existing server pool from the drop-down menu or create a new one by clicking New Server Pool. Optionally, you can configure advanced settings such as access log, connection limit, rate limit, etc., for the virtual server. Click Save.
• You have successfully created a logical load balancer for several web servers using NSX-T Manager UI.

To troubleshoot ICMP traffic and make any necessary changes to the Boston application security policy, you need to follow these steps:

• Log in to the NSX Manager UI with admin credentials. The default URL is https://.
• Navigate to Security > Distributed Firewall and select the firewall policy that applies to the Boston application. For example, select Boston-web-Application.
• Click Show IPSec Statistics and view the details of the firewall rule hits and logs. You can see which rules are matching the ICMP traffic and which actions are taken by the firewall.
• If you find that the ICMP traffic is allowed by a rule that is not intended for it, you can edit the rule and change the action to Drop or Reject. You can also modify the source, destination, or service criteria of the rule to make it more specific or exclude the ICMP traffic.
• If you find that the ICMP traffic is not matched by any rule, you can create a new rule and specify the action as Drop or Reject. You can also specify the source, destination, or service criteria of the rule to match only the ICMP traffic from the main console to the Boston web VMs.
• After making the changes, click Publish to apply the firewall policy.
• Verify that the ICMP traffic is blocked by pinging the Boston web VMs from the main console again.You should see a message saying “Request timed out” or “Destination unreachable”.
