Cisco 3750-X management ethernet port

I have configure 3750-X fastethernet 0 interface with IP which is same subnet with my production LAN. according product manual, the management port should connect to seperated network.
Just curious, i have set up a additional switch and connect a uplink to 3750-X, my laptop also connected to 3750 as well, but i can't ping to the switch. I only can ping the Cisco 3750 when my laptop is connected to same switch with the F0 interface.

thanks

If I understand correctly. You can only ping the FA0 interface on the 3750x when you are connected to the switch that has an "uplink" port connected to the same interface? If you laptop is on another subnet then you will need a layer 3 device to do the routing to get the the FA0 port. The 3750 will do L3 routing for your, you just need to configure an vlan interface for the network that the other ports are on. If you need help doing that let's see some running configs for the 3750x and the other switch that you have connected.

My laptop is using same subnet with the F0 interface.
i tried plug F0 interface to gig interface of the switch itself. and i can't ping it. but the f0 can grap dhcp ip if i change it to ip address dhcp, and still cannot ping.

The only result that i can get through is when the F0 and my laptop is connected to seperated switch from 3750-X.

Trying to picture what your trying to accomplish .. if you just want to put the switch on your LAN then be able to access it . take the switch connect an Ethernet cable and plug it into the switch the other end , plug into your LAN data-jack ,, make sure the port is configured properly .accessport(switchport mode access) ,,check your vtp( sho vtp status),,check your domian name( ip domainname xxx),,you may have to check the vtp password , maybe,, once the port arps out it'll get and address....if your helper address and option route is correct in DHCP you should be good...remember the management port is vlan 1 ..having a look at you configs would help though

thanks nativevlan, what im try to achieve is intead get another switch work as management switch for that particular port, thinking if i can route the F0 cable and connect to front switch port to manage it.
If that is designed purpose for Out Of Band management, then it is fine.

thanks

So you are trying to set this switch up as a OOB management switch? Sounds like you already have that accomplished. Assign your switches a routed interface and then connect that interface to the management switch, then you would have a computer connected to that switch on the same network. You could probably do this easier by assigning a separate VLAN and VLAN interface for management and then apply inbound ACLs to the network and the VTY lines allowing only traffic from admins.

Thanks nativevlan.. currently all users are in defult vlan 1. can enable vlan routing for vlan 1 to route from management PC to OOB interface in other vlan..? if im not mistaken, there is not possible to have routing on defaut vlan...

thanks

nativevlan

You should be able to route on VLAN1.
