I also untagged port 25 with VLAN 9. Then, I created VLAN 5 and Untagged port 1,2,3 assign PVID 5. Everyting work wonderfully. expect, I lost the ablility to Manange the switch, once I applied the changes.... Yea, I can do a direct connect from my laptop into the switch (10.6.9.15), If i assign a static ip address on the laptop (10.6.9.16), but only if I unplug it from the cisco switch. Any ideas how to fix this issue ? Hello: I have a powerconnect 2748, and was able to create a trunk on my Cisco 3750 to port 48 on my 2748 (tag T) assign PVID 9 for (VLAN9).

No uplink to other switches are required as this is purely a network for the storage array and this new network receives a new IP subnet. As I understand the documentation, under VLAN Membership, I create a new vlan (vlan 2), then assign ports 17-24 (set to 'U'). Then, under VLAN Settings, I assign PVID '2' to ports 17-24, right? At this point, do I need to set anything on the end points (the VMware server allows me to configure a vlan ID for the virtual NIC that is connecting to the newly create vlan but the Drobo does not. When I do this though, traffic between the VMware host and the Drobo fails; if I do not set the VLAN Settings PVID (leave as default '1'), then I am able to ping devices on ports 17-24 from ports 1-16 on a device that has the same subnet info. Any help is appreciated. Hi, I’m trying to segment off a section of my 274 (ports 17-24) for use as a mini-iSCSI network between a VMware host and a Drobo storage device.

I created a Link Aggregated Group (LAG) on each one consisting of 3 ports on ports 2-4. This LAG membership was trunked. A lag allows the following: • Fault tolerance protection from physical link disruption • Higher bandwidth connections • Improved bandwidth granularity • High bandwidth server connectivity The only difference was I used 4 Dell powerconnect 2724 switches.

You should be able to see DHCP requests being sent over the trunk. I have a very similar setup as you can see. Yes. You should be able to see DHCP requests being sent over the trunk.

Just need confirmation from you techies to make sure vlan 1 is the same broadcast domain on both switches over the trunk. More information to my post above

SW1—-trunk—-SW2

Vlan1
ports 1-24 untagged
port 48 tagged

Vlan2
ports 25-48 untagged
port48 tagged

same configuration on both switches. Just need confirmation from you techies to make sure vlan 1 is the same broadcast domain on both switches over the trunk.

If I have vlan 1 and vlan 2 and I trunk to another powerconnect 2848 will I be able to see the vlan 1 across the trunk link meaning will they be in the same broadcast domain because I plan to run DHCP in vlan 1 across multiple 2848 switches. Reason I am asking is because of the management interface defaulting to vlan1 so I want to put a network on vlan 1 and a second network on vlan2 but want the capability to manage the switches from vlan1.

I created 3 vlans on the switch 1. vlan2 (internet connection) 2. vlan3 (web app) 3. vlan4 (database) vlan1 is the Dell default. In vlan2, I have the Internet cable and & the public interface of the FW. I picked port 11 to be the trunk where the internal fw interface is plugged in. I could ping servers on vlan1 from vlan3 but not vice versa. The fw guy told to create another vlan100 and match that up with the vlan100 tagged on the FW. So I created the vlan100 selecting a port leaving it untagged (U) and picked the trunk port 11 for the vlan100. After I did that, I lost connection to the Internet. I am not sure why that would make a difference to solve the problem of pinging vlan3 from vlan1. Please advise. Thanks. Shank,

On Port 11 & 12 I have a server running ESX with VMs configured for VLANs 10 & 50. In the cisco world i would "trunk" ports 11 & 12 so all VLANs come communicate across those ports. With a Dell 2716, do I simply tag ports 11 & 12 with each VLAN? So port 11 would have a "T" for VLAN 10 & 50 (same for port 12)?? If so, what PVID should be set for ports 11 & 12? Thanks...this was a great article!!!! here is my config:

- VLAN 10: Ports 1-5
- VLAN 50: Ports 6-10

Each Port is setup as “T” for the appropriate VLAN, and the PVID is set as “10″ or “50″ for each port.
