VLAN setup for SAN with management on existing data network
Currently we have an existing data network - 10.10.10.0 (255.255.255.0).
We have a EqualLogic PS4000 and two PowerConnect 6224 switiches in a stack.
I have done the following so far:
enable
configure
spanning-tree mode rstp
flowcontrol
vlan database
vlan 10
vlan 100
exit
interface vlan 1
exit
interface vlan 10
name Management
exit
interface vlan 100
name iSCSI
exit
ip address vlan 10
interface port-channel 1
switchport mode access
switchport access vlan 10
exit
interface ethernet 1/g1
switchport access vlan 10
channel-group 1 mode auto
exit
interface ethernet 2/g1
switchport access vlan 10
channel-group 1 mode auto
exit
interface ethernet 1/g2
switchport access vlan 10
exit
interface ethernet 2/g2
switchport access vlan 10
exit
interface range ethernet 1/g3-1/g24
switchport access vlan 100
no storm-control unicast
spanning-tree portfast
mtu 9216
exit
interface range ethernet 2/g3-2/g24
switchport access vlan 100
no storm-control unicast
spanning-tree portfast
mtu 9216
exit
exit
copy running-config startup-config
So, what I hope has happened is that ports 1-2 on each switch in the stack can be connected to our existing network to allow me access to the switch's http interface over that network. The remaining ports should be for use by the SAN.
Currently I can't see the switches on our existing network - despite plugging in a network cable to port 1 on switch 1 - which flashes like it's getting used.
I have tried to set an IP address on vlan 10 but I'm told that I can't have routing on the management vlan.
I'm sure I've overlooked something but I'm very new to configuring switches like this!

Port one seemed to be assigned to VLAN1 which I didn't think I was using. I moved the connection from our existing network in to port 2 - which then gave me access to the web interface where I could see for certain that VLAN10 (management) was on port 2 only on each switch in the stack.
So, I can at least get more visibility of what is happening now which should help going forward.
This effectively closes my issue of not being able to assign an IP address - VLAN1 seems to not allow that, but my VLAN10 does.

Hi,
Currently, our existing non-SAN network is on 10.10.10.x
I hoped that I'd set the new switches so that ports one and two on each switch could connect to that network and the remaining ports used just for the SAN traffic.
So far I've been connecting to the switch using a serial cable. When I try and see the IP address for the switch it says 0.0.0.0. When I try and set the IP for VLAN10 to something in the 10.10.10.x subnet I'm told that I can't have routing on a management vlan.
Ideally, I want an IP address for the switch on our existing data network so that I can get to the management web site that way. Before I created the two VLANs it did appear on our data network after getting an address from DHCP. Since adding the two VLANS that no longer happens.

can you give a net topology - would be helpful to understand your connection path.
"Currently I can't see the switches on our existing network - despite plugging in a network cable to port 1 on switch 1"
Are you connecting a server directly into this port to verify you've set up your managment correctly (there are two methods to access your switch - Telnet, GUI).

First chance I get I'll look over what youve sent (just got back from a long trip). A quick note on the null ip address (0.0.0.0); I assume you've set the switch inband managment to "ip addresss DHCP". This return tells you that it did not recieve the DHCP BPDU. Assign an available static ip address and attempt to do a quick ping to verify your path. If that works but no DHCP then I suggest you utilize the helper-address feature...
I'll get back to you on the rest.
