How do you troubleshoot a VPC?

To verify vPCs using the CLI, perform one of these tasks:

1. Purpose. Command.
2. show running-config vpc. Checks the status of the vPCs.
3. show vpc peer-keepalive. Verifies that the vPC peers have the identical type-1 parameters.
4. show vpc consistency-parameters.
5. show tech-support vpc.
6. show port-channel summary.

How do I know if VPC is working?

Verify that your VPC route table allows traffic to and from the internet.

1. Open the Amazon EC2 console.
2. In the navigation pane, under Instances, choose Instances.
3. Select your instance.
4. Choose the Description view.
5. Note the VPC ID.
6. Open the Amazon VPC console.

What happens when you create a VPC?

AWS will automatically create a default VPC for you and will create a default subnet in each Availability Zone in the AWS region. Your default VPC will be connected to an Internet gateway and your instances will automatically receive public IP addresses, just like EC2-Classic.

What is an internet gateway?

An internet gateway is a horizontally scaled, redundant, and highly available VPC component that allows communication between your VPC and the internet. An internet gateway supports IPv4 and IPv6 traffic. It does not cause availability risks or bandwidth constraints on your network traffic.

What happens if VPC peer link fails?

vPC peer-link failure If peer-link fails, then all the member ports from vPC secondary node will be suspended. Here important to note, keep-alive is active in this scenario, which allowing nodes to exchange heartbeat. Solution: Make sure peer-link is UP and running.

How do I check my VPC keepalive link?

What are the pros and cons of VPC?

VPC-enabled functions are allowed to stay idle for longer to increase the likelihood that existing ENis are reused. However, even with these optimizations, VPCs still impose serious scalability and performance limitations on Lambda functions. Learn more about AWS Lambda deployment in our guide: Deploying AWS Lambda with CloudFormation

What happens if there is a failover on a VPC?

Repeat rate and failover times are tunable parameters. This could have many impacts. New incoming L3 messages may fail to make it to their destination (in the case of a vPC member link failure).

What do I need to know about VPC consistency?

The vPC on the switch remains up and running. The global configuration, such as Spanning Tree Protocol (STP), and the interface-level configurations are included in the consistency check. Verify that all vPC interfaces in a vPC domain are configured in the same virtual device context (VDC).

What to do if VPC Peer Link fails?

In case vPC peer-link fails, check active status of remote vPC peer via vPC pk-link (heartbeat). If both peers are active, then Secondary will disable all vPC ports to prevent loops.
