Ok, did some more research on this, and this is what I found.  1. VLAN 1 is by default the management VLAN, which by default makes it non routable. So if you want VLAN1 to be routable, a different VLAN would need to be made the management VLAN. For instance if you made VLAN 5 and wanted it to be the management VLAN, you would run this command.  console(config)#ip address vlan 5  Which would make VLAN 5 the management VLAN, and then VLAN 1 would become routable at that point.  2. I was incorrect about the Trunk mode, we should change this to general mode. And make sure all VLANs are tagged. Similar to this.  console(config-if)# switchport mode general  console(config-if)# switchport general allowed vlan add 21,10,1,41 tagged  console(config-if)# end  The cisco should be using 802.1q for VLAN tagging, which I think you said was already set that way. Once that is set, let me know the outcome. Thanks.
I'm having trouble with configuring VLAN routing between L3 Dell 6224 and L2 Cisco 2970.  I don't know if I need routing on both our Dell 6224 switches and if all VLAN interfaces on all switches need an IP address, if only one 6224 will be providing VLAN routing. The VLANs were created on all Dell and Cisco switches.  There are only 4 VLANs: 1, 10, 21 and 41.  21 is a SAN VLAN and no other traffic should enter VLAN 21.  (Mainly concerned about routing between VLAN 1 and 10 at the moment.)  However, when I create a trunk between a 6224 and a 2970, the SAN spits out errors that the initiators log on to volumes.  That's a problem.  Not sure why this happens, if the SAN is on a VLAN that is not accepting any other traffic, tagged or untagged.  When I create a switchport in general mode instead of trunk mode and allow VLANs 1 and 10, the SAN error appear, but go away.  With either trunk mode or general mode, I can't PING clients from VLAN 1 to VLAN 10 or visa vera.  Clients can PING within their VLANs.  So, I guess this means there's a VLAN routing issue. What is "vlan routing 21 1", if routing is off on that VLAN interface?  Is it set globally? 1/g5 would have been the trunk to the 2970.  Uplink in the 2970 is a trunk. I have read the VLAN Interoperability App note #4.  Have also read the CLI PDF for the 6200 series switches. Thanks in advance for any guidance you can give.
