Re: Unable to reach Mgmt0 via ping from VDC to VDC in Nexus 7706

DJay11 · ‎10-18-2022

I need to access our core switch from VDCx (Core_VDC) to VDCy (Admin_VDC) via L2 via SSH. Upon pinging, getting an RTO reply. This is just once device. Should be able to access without passing through the gateway since mgmt IP is within the same subnet.

From Admin_VDC

it should work as expected, how is your mgmt0 interface connected ? where ?

VDC means 2 different devcies, that means, you need to have Layer 2 connectivity ?

mgmt0 is connected in the Server_VDC (Same device).

interface Ethernet5/31
description [LINK TO ADMIN_VDC]
switchport
switchport mode trunk
switchport trunk native vlan 501
no shutdown

interface Vlan501
description Management
no shutdown
ip address 172.26.1.1/24

This is just 1 physical device but different vdc.

I need to have a L2 connectivity in situation that FW is down. My only connection if ever FW is down is thru Core_VDC. No direct access to Admin_VDC in case our FW is down.
