Virtual PortChannel (vPC) Configuration

[@vijayabhaskar207]

Sir you are the very dedicated person for doing hardwork on networking, Just because of your hardwork somany students earned good knowledge on networking ......thank you my real hero .....hats of...

[@PMNetworking]

So nice of you

[@lovenature3658]

Great explaination, please make more videos on nexus switch

[@johnlj_ciscocertified]

great help for nexus switch newbie like me, thanks mate.

[@PMNetworking]

Glad it helped

[@sidrish143]

Very informative thanks for sharing 😊

[@PMNetworking]

My pleasure 😊

[@AjayKumar-fm2rm]

Sir you have a clip discussing the same port channel but having traffic inspected by the firepower appliance.

[@mysuruvideography1284]

It's Great tutorial keep it up !

[@PMNetworking]

Thanks a lot!

[@dulichbatngo1342]

Great explaination, thank you very much

[@PMNetworking]

You are welcome!

[@tharakeshk8594]

very nice explanation sir

[@PMNetworking]

Thanks for sharing feedback

Hello Sir, First of all thanks for making a video on Nexus.... I request you to make VPC Complex topology for better understanding of this concept

[@PMNetworking]

Sure I will

[@jeffreysheltonjohnwesly7062]

nice explanation

[@PMNetworking]

Thanks for liking

After vpc domain config sw1 &2 are act as a single logical switch? Like stacked or vss... Show vpc 20 comand, it should show members of both switches like te 1/0/3, te 2/0/3 right? Sir can you do one video acl in and outbound direction how its matches with packet source ip

[@pramodghorpade9804]

Sir , if both peer link and uplink of primary goes down in VPC , what will happen as uplink failure will suspend secondary member ports

Nice video, great learning! I want to know how to add NX OS images in EVE-NG. If you can make video for this. This would be much appreciated. Thanks

Hello, Please resolve below query. I have 2 nexus 9k in vpc and operating as L2 switch..above that I have fire eye device as upstream and above that I have. Fortigate firewall as gateway for down stream...My requirement is I have to add 2 another switches in downstream how will I add

To add two additional switches in your downstream setup, you should ensure they integrate smoothly into your existing network while maintaining redundancy and avoiding any potential loops. To add two additional switches in your downstream setup, you should ensure they integrate smoothly into your existing network while maintaining redundancy and avoiding any potential loops. Here’s a step-by-step guide: ### Step 1: Preparation 1. **Ensure VLAN Consistency**: Ensure the VLANs configured on your existing Nexus 9k switches are propagated to the new switches. 2. **Check VPC Configuration**: Confirm the VPC configuration between the two Nexus 9k switches is healthy and stable. 3. **Plan the Connections**: Decide how you'll physically connect the new switches to your existing network. Typically, you would connect each new switch to both Nexus 9k switches for redundancy. ### Step 2: Connect the New Switches 1. **Connect Switch 1 to Nexus 9k Pair**: - Connect an uplink from the new Switch 1 to Nexus 9k Switch A. - Connect another uplink from the new Switch 1 to Nexus 9k Switch B. 2. **Connect Switch 2 to Nexus 9k Pair**: - Connect an uplink from the new Switch 2 to Nexus 9k Switch A. - Connect another uplink from the new Switch 2 to Nexus 9k Switch B. ### Step 3: Configure the Nexus 9k Switches 1. **Configure Interfaces**: - Configure the interfaces on both Nexus 9k switches that will connect to the new switches. For example, if you are using Ethernet1/10 and Ethernet1/11 on both Nexus 9k switches, you would configure them as trunk ports and include the necessary VLANs. ```shell interface Ethernet1/10 switchport mode trunk switchport trunk allowed vlan channel-group 10 mode active interface Ethernet1/11 switchport mode trunk switchport trunk allowed vlan channel-group 11 mode active ``` 2. **Configure Port Channels**: - Create port channels on the Nexus 9k switches for the connections to the new switches. ```shell interface port-channel 10 switchport mode trunk switchport trunk allowed vlan vpc 10 interface port-channel 11 switchport mode trunk switchport trunk allowed vlan vpc 11 ``` 3. **Add Port Channels to VPC**: - Ensure the port channels are added to the VPC domain. This step is crucial for redundancy and load balancing. ```shell vpc domain 1 peer-keepalive destination interface port-channel 10 interface port-channel 11 ``` ### Step 4: Configure the New Switches 1. **Trunk Ports Configuration**: - Configure the uplink ports on the new switches to connect to the Nexus 9k switches. Ensure they match the trunk settings. ```shell interface Ethernet1/1 switchport mode trunk switchport trunk allowed vlan channel-group 10 mode active interface Ethernet1/2 switchport mode trunk switchport trunk allowed vlan channel-group 11 mode active ``` 2. **Configure Port Channels on New Switches**: - Create corresponding port channels on the new switches. ```shell interface port-channel 10 switchport mode trunk switchport trunk allowed vlan interface port-channel 11 switchport mode trunk switchport trunk allowed vlan ``` ### Step 5: Verification 1. **Verify VPC Status**: - Check the VPC status on the Nexus 9k switches to ensure the new port channels are up and part of the VPC. ```shell show vpc brief ``` 2. **Verify Connectivity**: - Test connectivity from devices connected to the new switches to ensure they can reach upstream devices and the Fortigate firewall. 3. **Monitor the Network**: - Monitor the network for any potential issues such as loops or misconfigurations. By following these steps, you will have successfully added two new switches to your existing Nexus 9k VPC setup, maintaining redundancy and optimal network performance. 1. Ensure VLAN Consistency: Ensure the VLANs configured on your existing Nexus 9k switches are propagated to the new switches. 2. Check VPC Configuration: Confirm the VPC configuration between the two Nexus 9k switches is healthy and stable. 3. Plan the Connections: Decide how you'll physically connect the new switches to your existing network. Typically, you would connect each new switch to both Nexus 9k switches.

​@@PMNetworkingHello, In this Back to back VPC all 4 switches are acting as Layer 2 only...Is there any chance of loop happen? As servers are connected on upper side (existing switches) vpc switches also??

[@mannylenis9312]

Good Explanation

[@PMNetworking]

Keep watching

[@gokulhazarika3534]

Nice video sir..if possible please upload a lab with two isp with two different setup eg. Two routers , two firewall, two nexus switch, multilayered switch and access switch

Hello sir, I would like to know when will you broadcast live?

[@nareshabhira8728]

Hi sir- can u pls explain and do the configuration below topic- Please IDP websense how to apply pbf QOS creation on router

[@PMNetworking]

Sure

[@12123vijay]

What is the maximum ports that can be assigned to lacp?
