I'm about to implement it in my environment but I would like to confirm a few things with you if that's ok? This is what I have in my environment: Cisco ASA 5510 Port 1.1 - VLAN 10 (Local LAN) Port 1.2 - VLAN 20 (DMZ) Both are using PORT 1 on the Cisco. 2724 Port 24 - connected to Cisco ASA PORT 1 - VLAN Membership ID 10 & 20 is set to T. Port 23 - connected to 3Com 4200G - VLAN Membership ID 10 is set to T. Port 1-4 - connected to VMware Server - VLAN Membership ID 10 & 20 is set to T because few VM servers would be on the DMZ and some on local LAN. Port 5-22 connected to LAN PCs on VLAN 10 so I left the VLAN Membership to U. Now, this is the tricky part. I don't know what to set on VLAN Port Setting. Right now, everthing is defaulted to PVID 1. How do I make Port 24 and 1-4, PVID 10 & 20? Or I should just leave it at PVID 1? Do I need to make Port 23, PVID 10? Any help or suggestion would be appreciated. :) Thanks. CP Hi Shankaran,

Thanks for a great article.
I’m about to implement it in my environment but I would like to confirm a few things with you if that’s ok?

This is what I have in my environment:
Cisco ASA 5510
Port 1.1 – VLAN 10 (Local LAN)
Port 1.2 – VLAN 20 (DMZ)
Both are using PORT 1 on the Cisco.

2724
Port 24 – connected to Cisco ASA PORT 1 – VLAN Membership ID 10 & 20 is set to T.

Port 23 – connected to 3Com 4200G – VLAN Membership ID 10 is set to T.

Port 1-4 – connected to VMware Server – VLAN Membership ID 10 & 20 is set to T because few VM servers would be on the DMZ and some on local LAN.

Port 5-22 connected to LAN PCs on VLAN 10 so I left the VLAN Membership to U.

Now, this is the tricky part.
I don’t know what to set on VLAN Port Setting.
Right now, everthing is defaulted to PVID 1.

How do I make Port 24 and 1-4, PVID 10 & 20? Or I should just leave it at PVID 1?
Do I need to make Port 23, PVID 10?

Any help or suggestion would be appreciated. :)
Thanks.

This way all the traffic will be passed at the switch level. Can this be done on this model?

I'm back now though. I don't have these devices anymore to assist but I will try my best from memory. Brian you are probably on the wrong VLAN. Greg glad I could be of help. Steffo I am unaware of the similarities between that device and the 2700 series. Are any of the changes mentioned above visible in your device? Sorry for the LATE responses guys, been so busy.

There are so many places in my switch(PowerConnect 5424) that have LAG settings. Hello Shankaran,

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.
