Trunk between Cisco and Netgear

Hello,

 

At work we're working with cisco for Core and access layer (switches). Because we don't have enough outlets at certain points throughout the building we are forced to either make more or use a small switch. The problem is that we use different vlans for our printers and pc's. For this to work I need to set up a trunk but this won't work with the GS105. I'm looking for a netgear switch with which this WOULD work. It should have max 5 ports.

Any recommendations?

 

Thanks in advance.

Re: Trunk between Cisco and Netgear

I don't think that at 5 ports you'll be able to find a model satisfying your needs (not only with Netgear). Most models with proper VLAN support start at 8 ports or higher. Most switches of the smart managed pro line should have full VLAN support, hence models like the GS308T, GS310TP could be a fit.

 

However if you are used to CLI and plan on using many of these smaller switches, you might consider a fully managed model with a CLI and a console port. However I have come to realize that in the case of Netgear they don't make that many small, yet fully managed switches that are fanless (which is likely a requirement in an office space). That said: The same problem exists with other vendors as to.

 

The only fanless model (without PoE) that I have come across still seems to be the GSM5212 from the M4100 line. It should still be much less expensive than what Cisco proposes in that space though. If you are familiar with the IOS CLI, the Netgear CLI is very similar and easy to pick up.

The GSM5212 as mentioned above and also the GS108T and GS308T would fit the bill.  As a bonus, both can be PoE powered to simplify deployment, are fanless, and come with low port count.

 

FWIW, the GSM5212 really is a much better switch.

Hello,

After fiddling with this I got it going using Advanced VLAN 802.1q.

I think VLAN 1 has to exist but as I had been fiddling with this for hours I didn't want to risk removing it entirely.

Port 1 is my uplink.

Port 3, 4, 5 are links, each to different VLANs.

As using VLAN 1 is a no-no because it's usually the default everywhere I will give an example of mysetup using 11, 12, 13, and 14.

Cisco config real quickly:

 

usps#show run int gi 1/22
Building configuration...

Current configuration : 196 bytes
!

interface GigabitEthernet1/22
description wifi-uplink
switchport trunk encapsulation dot1q
switchport trunk native vlan 11
switchport trunk allowed vlan 11-14
switchport mode trunk
end

 

VLAN > 802.1q > Advanced > Port Configuration:

VLAN IDPort Members
1  2       
111         
121   3     
131     4   
141       5 

 

VLAN > 802.1q > Advanced > VLAN Membership:

 

VLAN ID 1: Port 2 (Untagged)

VLAN ID 11: Port 1 (Untagged)

VLAN ID 12: Port 1 (Tagged), Port 3 (Untagged)

VLAN ID 13: Port 1 (Tagged), Port 4 (Untagged)

VLAN ID 14: Port 1 (Tagged), Port 5 (Untagged)

 

VLAN > 802.1q > Advanced > Port PVID:

 

PortPVID
  
111
21
312
413
514

 

Hope this helps anyone else going forward.

 

There is just one issue. The IP I gave it which is on VLAN 11 takes 6 to 7 times longer than the other VLANs. Ports 3, 4, 5 connect to devices. I'm using this like an edge switch. So I average about 0.25ms from my core switch to the devices on port 3, 4, and 5 respectively. But I'm at about 2ms from my core switch to the Netgear switch. It makes no sense, I probably have something messed up somewhere but not sure where.

 

Regardless as the edge devices have low latency and everything is just fine, no packet loss, loops or drops, I'm good as I got what I wanted. A Cisco trunk w/ 802.1q tagging and a native working.

Model: GS105E|5 ports ProSafe Unmanaged Plus switch, GS108E|8 ports ProSafe Plus switch

Answered in the post here.

 

As you posted this now again in the Managed Switches community section, please note none of the Plus models you tagged [Gigabit Plus Switch Series (GS105Ev2), Gigabit Plus Switch Series (GS108E)] are in any aspect Managed Switches.
