Will SGE2010 do the tagging?

Answered Question
May 16th, 2011

Hi all

I'm trying to find out if SGE2010 will do the following feaute:

Port 1: Vlan X Untagged

Port 2: Vlan Y Unttaged

Port 3: Vlan X tagged, Vlan Y tagged.

port 3 would be a ASA apliance with two virtual interfaces on that VLANS. Will the swich add the tags when untagged frames comes from port 1 or 2 and will forward it to port 3 tagged.

Will switch remove tags from port 3 and deliver it to corresponding Port 1 or Port 2.

I've achieved this behaviour with a netgear switch.

Thanks

I have this problem too.

Hi Jose,

Why not try Cisco Network Assistant (CNA), it's availble to configure the Catalyst switch, and you don't have to be highly skilled with cisco CLI to use it. Grab it from the following location;.    http://www.cisco.com/en/US/products/ps5931/index.html

Check out the manual or release notes on CNA there might be a couple of commands needed on the switch so that CNA can gain access to the switch.

I just tried the following via CNA, it should be easy.

Make sure you select the option to  save the configuration.  If you want a CLI example, here is a configuration example;

Jose,


The switch will do that for you, it will remove the tag once it comes back in on the trunk port.


However, this switch will not allow you to tag vlan 1 so you will have to use 2 different vlans other than one and tag them on the trunk port.

Hi David

Thanks! ok, i wont use VLAN 1 at all, I need 8 different VLAN, i've seen these switches supports up to 256.

Is that correct?

Yes Mr. Montes that is correct.  The switch will support up to 256 vlans.

Let me ask you one final question...

These SGe2010 will be in same envirnment as Catalyst 3750

Could you please provide an example for this configuration on a Catalyst?

Port 2 --> Untaged VLAN2

Port 3 --> Untaged VLAN3

Port 4 --> Untagged VLAN4

Port 5 --> Unttaged VLAN2, Tagged VLAN3, Tagged VLAN4.

Thanks!

Hi!

Thanks! But I'd rather get used to IOS

I think this is equivalent for the complex port

interface GigabitEthernet0/17

  switchport trunk encapsulation dot1q
switchport trunk native vlan 100
switchport trunk allowed vlan 100,200
switchport mode trunk

Thanks a lot!!
