Management VLAN
Hello,
I'm a bit confused with VLANs. Sorry about that.
I have a FX2 with 3 FC630 running ESXi and 2 FN410T as IOM. Uplink is a S4820T.
On the S4820T I use VLAN 1 as in the FN410T all ports are in this VLAN untagged. For iSCSI i use other VLANs.
My question what I don't understand is now the Management VLAN. Can I use a VLAN wich is not the Default-VLAN for the Management-Interfaces and can I mix Tagged and Untagged ports? This is necessary in my opinion because I want to use the same port of the router. This would than mean that the router has the default-VLAN for user-traffic and another VLAN for management. But the Management-Interface cannot bound to a VLAN. Now I'm stuck.
Thx in advance

I think I understand a bit more and I'm one step closer to the solution.
Now I have a router wich is the gateway for the User-Traffic without VLAN. It has a Subinterface for VLAN 157 and a different subnet for management. Routing on the Router seems okay (it's a Juniper Firewall Device). But I cannot ping the management-address of the connected Switch. I also tried to configure a management-route with no success.
Here are the interfaces of the Switch:
interface TenGigabitEthernet 0/28
no ip address
portmode hybrid
switchport
speed 100
no shutdown
!
interface TenGigabitEthernet 0/29
no ip address
portmode hybrid
switchport
speed 100
no shutdown
!
interface ManagementEthernet 0/0
ip address 192.168.152.243/24
no shutdown
!
interface Vlan 152
no ip address
tagged TenGigabitEthernet 0/28-29
shutdown
!
Are there any other things I have to think about? User-Traffic is coming fine thru the Switch.

Here is the information I have collected about the two management options.
OOB management:
This is done through the management interface. This OOB interface is not routable with the other traffic on the switch. This interface needs to be placed on a subnet separate from all other VLANs, and needs to have a management route in place.
Dell(conf)# interface ManagementEthernet 0/0
Dell(conf-if-ma-0/0)# ip address 10.10.10.2/24
Dell(conf-if-ma-0/0)# no shutdown
Dell(conf-if-ma-0/0)# exit
Dell(conf)# management route 10.10.10.1/24
In-band VLAN management:
This method is done through the VLAN interface.
Dell(conf)# interface vlan 1
Dell(conf-if-vl-1)# ip address 10.10.1.2/24
Dell(conf-if-vl-1)# exit
Dell(conf)# ip route 10.10.1.1/24 vlan 1
CMC console connection:
From the CMC there is a racadm command that can be run to connect to the switch console.
racadm connect -b switch-1
I am still not certain how the CMC connection was interfering.
The following command can be used to check the management interface/route.
Dell#show ip management-route all
Destination Gateway State Route Source
----------- ------- ----- ------------
10.11.0.0/16 ManagementEthernet 0/0 Connected Connected
The state and route source should come up as connected.

Oh, probably I forgot the Management-Route. I'm not completly sure now. And I have the management-network in it's own VLAn now up and running.
Thx
