CISCO 2900XL AND BAYSTACK 450 TOGETHER WITH TRUNK LINK

[jippo]

HI!

I have this kind of problem:

I have Cisco Catalyst 2900XL and Baystack 450-24T switches. Both switches has three VLAN. Trunk link between two baystack switches is working well, but the trunk link between Cisco and Baystack is not working so well.

I have set the cisco port to a trunk and used type dot1.q and then set the trunk on the Baystack as tagged a member of all the vlans. They are connected via fibre and the link is up and working fine. Also all ports work fine IF they are in VLAN 1 (in Cisco switch) but if I change any of Cisco switch port other VLAN then there is no response that port.

I have tried almoust everything and I'm losing my hope!
Please give me some HELP !

Do the VLAN numbers on both switches match? Are the VLANs in question "allowed" on the Cisco trunk port?

Can we get to see that part of the Cisco configuration (trunk port and associated vlans)?

Hi!

Okey, VLAN numbers is same both switches they ID numbers in Cisco are 1,2 and 3

Here is configurations:

kacd49#sw int fa 1/1 sw

Name: Fa1/1
Switchport: Enabled
Administrative mode: trunk
Operational Mode: trunk
Administrative Trunking Encapsulation: dot1q
Operational Trunking Encapsulation: dot1q
Negotiation of Trunking: Disabled
Access Mode VLAN: 0 ((Inactive))
Trunking Native Mode VLAN: 1 (default)
Trunking VLANs Enabled: ALL
Trunking VLANs Active: 1-3
Pruning VLANs Enabled: 2-1001 <-- WHAT THAT MEAN?

Priority for untagged frames: 0
Override vlan tag priority: FALSE
Voice VLAN: none
Appliance trust: none


kacd49#s vlan

&quot;Pruning VLANs Enabled: 2-1001&quot; are the vlan not allowed accross this link. you need to turne off pruning for you vlans. (sorry i don't remeber the commands)

HI!

Okey I turn off pruning thode vlans which I use, but it does not help.

Do you or anybody else have more good tips that I could test?

Thanks anyway

If you display statistics on the vlans in question, do you see any of the counters increment?

Can you get screen captures from the Baystack switch. I just went through this with at 350 and I didn't find the documentation description for the dot1q trunking to be intuitive, but I did get it to work. The important point was the designation of tagging the port used for trunking, while not tagging the access ports.

HI!

What do you mean about vlan statics?
If you mean, Display Port Statistics, then answer to you question is yes. Trafic between cisco and bay is working fine if all port in cisco is on VLAN 1

This is the port that is connected to Cisco

VLAN Port Configuration



Port: [ 25 ]
Filter Tagged Frames: [ No ]
Filter Untagged Frames: [ No ]
Filter Unregistered Frames: [ No ]
Port Name: [ Port 25 ]
PVID: [ 1 ]
Port Priority: [ 0 ]
Tagging: [ Tagged Trunk ]

AutoPVID (all ports): [ Disabled ]

Use space bar to display choices, press <Return> or <Enter> to select choice.
Press Ctrl-R to return to previous menu. Press Ctrl-C to return to Main Menu.

And this is VLAN 1:

VLAN Configuration

Create VLAN: [ 1 ] VLAN Type: [ Port-Based ]
Delete VLAN: [ ] Protocol Id (PID): [ None ]
VLAN Name: [ default ] User-Defined PID: [ 0x0000 ]
Management VLAN: [ Yes ] VLAN State: [ Active ]

Port Membership
1-6 7-12 13-18 19-24 25-28
------ ------ ------ ------ ------


Unit #1 TUUUUU UUUUUU UUUUUU UUUUUU TTTU


KEY: T = Tagged Port Member, U = Untagged Port Member, - = Not a Member of VLAN
Use space bar to display choices, press <Return> or <Enter> to select choice.
Press Ctrl-R to return to previous menu. Press Ctrl-C to return to Main Menu.


Can you capture you configuration on your cisco switch ?

Thanks!

1. Do NOT configure the BS450 uplink port as &quot;trunk&quot;. &quot;trunk&quot; means something different on BS450 - comparable to Cisco EtherChannel. BS450 &quot;tagging&quot; is equivalent to Cisco &quot;trunk&quot;.

2. Disable &quot;pruning&quot; on the Cisco (has been stated before).

3. For the uplink port on the BS450 configure VLAN 1 as &quot;untagged&quot;, all other VLANs as &quot;tagged&quot;

4. To put a port on the BS450 into another VLAN, e.g. VLAN 2, set it to &quot;not a member&quot; in VLAN 1 and to &quot;untagged&quot; in VLAN 2.

Unfortunately, the philosophy and terminology for VLANs is very different between Cisco and Nortel (and a lot of other vendors, for that matter).
