Management Ethernet Interface

I am kinda confused.
L2 switch cannot be controlled by ip address but we can control it via a management ethernet interface.
where goes the connection of the management ethernet interface go to?

Are you referring to where does traffic traverse?

A L2 switch needs a management IP, we then trunk the device to a L3 switch for routing purposes (i.e. inter-vlan routing). You will also want to designate a default gateway on your L2 switch that will most definitely point to the L3 SVI on the Core switch as an example.

L3 Switch will have as an example

interface vlan 10
ip add 192.168.10.1 255.255.255.0

interface vlan 20
ip add 192.168.20.1 255.255.255.0

interface vlan 30
ip add 192.168.30.1 255.255.255.0

Now let's say VLAN 10 is our Mgmt Vlan, meaning only our network devices will be assigned IP's on this segment. So our L2 switch will look like this

interface vlan 10
ip add 192.168.10.20 255.255.255.0

ip default-gateway 192.168.10.1

Now you can set your L2 vlans for 20 and 30

vlan 20
name Finance

vlan 30
name Engineering

Now configure a trunk interface to your L3 switch

interface G0/1
switchport mode trunk
description ** trunk - CoreSW G0/1 **

Configure access ports on your L2 switch

interface FastEthernet 0/1
switchport mode access
switchport access vlan 20
spanning-tree portfast
spanning-tree bpduguard enable

interface FastEthernet 0/2
switchport mode access
switchport access vlan 30
spanning-tree portfast
spanning-tree bpduguard enable

All VLANs by default will span the trunk port, so there you go!

It's a L3 host port. You can basically connect your computer to it and use the management port instead of the console port to manage it. It's on the front of some of the newer 2960S. I took a pretty picture for you of where it is on the front right next to the console port:

It's capable of some pretty basic management like Telnet, SSH, etc. It's usually Fastethernet0

Unless of course, you mean the SVI on the switch and then we're talking about something different (See RouteMyPacket's explanation above)

You are so smart Iris, I was assuming "management" of the switch itself..not why or how we utilize Mgmt Interfaces. I typed an awful lot to be wrong. ha

He probably meant exactly what you explained but on the off-chance he was actually talking about the management port, well, there he goes :P He gets both explanations from us

So I am configuring a SVI on the management interface.
Am I right or wrong?
