I got the opportunity to play around with a Dell managed switch from the 2000 series with OS10. I tried to configure a management IP adress 10.10.12.141 (/24) according to the manual but somehow failed miserably, so I have a few questions (Dell OS10 commands as far as I can remember).

First, configuring it via DHCP works as expected, so I know the network is working and DHCP is served. I can SSH into the device/can ping other devices from the device:

configure
interface mgmt 1/1/1
ip address dhcp
no shutdown
copy running-config startup-config

But as soon as I switch to a static IP I can't reach the managed switch nor can I ping other systems from the switch:

configure
interface mgmt 1/1/1
no ip address dhcp
ip address 10.10.12.141/24
no shutdown
copy running-config startup-config

Now I am a bit confused because it looks like I make a fundamental mistake (Question 1: What mistake). From what I know and can remember about the OSI layer 2 and 3 a ping in a local network doesn't require a gateway nor a configured management route. The source devices takes the target IP/own IP + subnet and checks if the target address is within the network. If so the ARP table is checked to lookup a potential MAC adress for the target IP adress (If not, an ARP request is sent through the network). Then the frame is created and sent (Question 2: Is this correct).

In addition as question 3: How to I configure a potential gateway 10.10.12.254 (Syntax wise) for the network, so I can leave the current network (Assuming my understanding from question 2 is correct).

    The management interface of a switch is like a host on the network, so, yes, it does require a configured gateway to be able to send traffic to a different network. The management interface does not take part in the switching, which does not require a gateway to switch, but the management of the switch does require a gateway. – Ron Maupin Sep 30 at 18:12

    Not sure about Dell, but try ip route. – Zac67 Sep 30 at 19:08
