Nexus 3k can´t connect by remote access

[marcio.tormente]

Hello Folks!

I have a nexus 3k as L2 configured just the mgmt0 with an IP 101.1.1.2/20 with default route on the management VRF point to 10.1.1.1.1 that is my firewall.

I can´t even ping the core from any device, much less access by remote access.

Anyone knows what is missing?

Thanks

Hi,

If you are trying to ping any device from the Nexus, you would need to use the vrf as the source.

ping 101.1.1.1 vrf <vrf name>

Hello Reza!

It is the opposite, I'm trying to ping the Nexus from any other device from the same network and I can´t.

The goal is to ping and access using SSH, I already enable the feature ssh.

First form nexus you able to ping 10.1.1.1 ? using VRF, is this works ?

From FW are you able to ping 10.1.1.2 ?

Do you have FW allow ICMP from your network ? do you see routing table have this IP address ?

(if this is p2p IP address, how is other device able to know how to reach this IP, you sure need Routing arrangement right ?)

Hello, I clicked on the wrong button, this is not solved.

this is a flat network, all devices are in the same network /20.

It is not possible to ping from or to Nexus.

It is not possible to ping from any device, firewall, workstation or other switches.

when you mentioned flat network, VRF means separate instance routing it does not participate in GRT network.

i suggest below if you like the flat network to work.

Remove VRF config  from mgmt  interface and configure IP address again and test it,
