Hello,
i recently inherited a small network composed entirely of enterasys gear.
I have been reading the many helpful posts in this forum, including the faq on the matrix n-series on how to create a 802.1q trunk, but still im struggling and im not one to give up but i decided to reach out for help.
Basically i have this setup with 2 remote locations:
- Site A with the matrix n7
- Site B with the B5
- Trying to setup a new vlan in the N7 and having it forward the new VLan across the trunk to the B5...simple eh...well, not for me 😞
The moment i create a new vlan and tag that vlan to the port, i lose connectivity between the 2 switches.
- In matrix n7 i have this:
set vlan create 2-11,99
set vlan name 2 Oficinas
set vlan name 3 Maq_Cafe
set vlan name 4 DataCenter
set vlan name 5 Piso1
set vlan name 6 Piso2
set vlan name 7 VilaConde
set vlan name 8 vlan8
set vlan name 9 consulta_externa
set vlan name 10 ILOS
set vlan name 11 vc2
set vlan name 99 outside
clear vlan egress 1 host.0.1;ge.1.23,25-48,52,54;rtr.1.1;ge.2.23-48,52;ge.3.37-48
set vlan egress 1 lag.0.1-48;ge.1.1-22,24,49-51,53;ge.2.1-22,49-51,53-54;ge.3.1-36,49-54 untagged
set vlan egress 2 lag.0.1-3;ge.1.49-53;ge.2.49-54 tagged
set vlan egress 2 ge.1.54 untagged
set vlan egress 3 lag.0.1-3;ge.1.49-54;ge.2.49-54 tagged
set vlan egress 4 lag.0.1-4;ge.1.49-54;ge.2.49-54;ge.3.1-2 tagged
set vlan egress 4 ge.1.25-48;ge.2.23,25-48;ge.3.37-48 untagged
set vlan egress 5 lag.0.1-3;ge.1.49-51,53-54;ge.2.49-54 tagged
set vlan egress 5 ge.1.52 untagged
set vlan egress 6 lag.0.1-3;ge.1.49-54;ge.2.49-51,53-54 tagged
set vlan egress 6 ge.2.52 untagged
set vlan egress 7 ge.2.24 untagged
set vlan egress 8 lag.0.5;ge.1.53;ge.2.53 tagged
set vlan egress 9 ge.3.49-50 tagged
set vlan egress 10 lag.0.1-5;ge.1.47-54;ge.2.24,49-54;ge.3.1-2 tagged
set vlan egress 10 host.0.1;ge.1.23 untagged
set vlan egress 11 ge.2.24 tagged
set vlan interface 9 create
- In the B5 i have this:
set vlan create 7
set vlan create 10
set vlan create 11
set vlan name 11 vc2
clear vlan egress 1 ge.1.7
set vlan egress 10 ge.1.1;ge.1.41-48;lag.0.1-6 tagged
set vlan egress 11 ge.1.43;ge.1.45 tagged
set vlan egress 11 ge.1.7 untagged
In bold is the port assigned vlan that its used for the trunking between the 2 switches, but i see them as untagged at port ge.2.24 in the N7 side and as tagged at port ge.1.43 in the B5 side.
What im trying to do is to tag same vlan 7 at both ends of the trunks on respective ports and configure a new vlan to span across the trunk, but the minute i add set vlan egress 7 ge.1.43 tagged to the B5 side, and tag the ge.2.24 at vlan 7 in the N7 side, i lose everything.
I really hope anyone can help me with this, and explain to me what am i not seing with the concept used by extreme networks, as i will be needing this to manage this network and im really depending on it.
Sorry for the long text .
Thank you.
António.

While doing my daily, painful by now i must say, visit to this small EN network, i have noticed a protocol activated in the N7 side: GVRP.
Read an article in this community about that protocol, and would be very happy if anyone could take the time to tell me if the issue im having with VLAN creation can be related to this protocol.
Thank you.

Hi Tyler,
thank you for your quick reply. Unfortunately i have been away for personal reasons, but im returning to this subject as it is important for me to get it fixed.
I dont have acess to the SW at the moment, but i do know that the management vlan for the B5 is Vlan1.
As soon as i can i get the info you requested. If you can find just by looking at the config what is wrong, it would be great.
Thank you again..
António.

Antonio,
Try running the command 'show port egress ge.2.24' on the N7 and 'show port egress ge.1.43' on the B5. Those commands should give you a good idea about what's tagged and what's not tagged. That command does require the port link state is up though.
Right now it looks like the following is true for the N7:
ge.2.24 is:
Untagged - VLAN 7
Tagged - VLAN 10,11
B5:
ge.1.43 is:
Tagged - VLAN 10,11
Check to see if the show port egress shows the same information. That will help determine what is going on. Also, what vlan is the management of the B5 on? You can find this out by typing 'show host vlan'.
