Can`t make SVI or port promiscuous in NX-OS

Hello,

I am trying to do a lab in CML for my studies in Private VLANs, and I can`t seem to make the SVI or the interface eth5/1 act as a promiscuous port. I am using a 9000v NX-OS. The community and isolated ports work fine, but they can`t reach the SVI or the eth5/1 configured as promiscuous.

Hello @BertiniB,

You have correctly configured the interface Ethernet 5 as a promiscuous port and associated it with the primary VLAN 50 and secondary VLANs 60, 70, and 80. However, you have also assigned it to access VLAN 50 (switchport access vlan 50). This is not necessary and could be causing issues.

--To fix this, remove the line switchport access vlan 50 from Ethernet 1/5.

In the output of your show interface private-vlan mapping, it appears that interface Ethernet 1/5 (promiscuous port) is not properly mapped to the secondary VLANs 60, 70, and 80. Instead, it is only associated with VLAN 50:

--To fix this, you need to correctly map the promiscuous port Eth1/5 to the secondary VLANs.

interface Ethernet1/5
no switchport access vlan 50
switchport private-vlan mapping 50 60,70,80

After making these changes, please verify the mapping using [show interface private-vlan mapping].

 

Best regards

Hello M02@rt37, thanks for the reply!

I did all the commands and the port still doesn't show in the PVLAN mapping and the Community and Isolated ports still can't reach the SVI.

BertiniB_0-1691639516439.png

As you can see from the picture below, the server connected to a community port still can't ping the SVI:

BertiniB_1-1691639579443.png

BertiniB_2-1691639672657.png

Could this be a bug of the NX-OS 9000v? Because it seems I did everything correctly according to the official Cisco documents.

Hello @BertiniB,

Your configuration seems to be good.

Do you have ARP entries after icmp attempt?

Do you check about any  security software on the devices is not interfering with the network communication ?

In the Server connected to the interface Eth1/3 (Community Port) the following ARP entries are:

BertiniB_0-1691650810496.png

Interestingly, it seems that the 9000v was able to learn the MAC address of the server-1(192.168.0.3):

BertiniB_1-1691651020812.png

It doesn`t seem to be a security software, since I can ping from the SVI to the other server running the same OS (Tiny Core Linux).  Also, I can ping the servers in the same community (server-1 and server-2):

BertiniB_2-1691651158833.png

They are all running Tiny Core Linux in CML.

OK @BertiniB 

Thanks for the output.

Since is Linux, is it possible to tcpdump from you Linux in order to see the icmp echo request from N9k ?

Sorry for the late response.

There is no tcpdump in the TinyCore Linux. I however captured the frames between the SVI and Community Server:
