asked on
management vlan for 2950
I am trying to configure management vlan for my new 2950 to not use vlan1. Upstream is a ASA 5500.
This switch will need to support etherchannel and multiple vlans for other devices. Does anyone have a configuration example?

Yes. You can use etherchannel between the two switches.

Does the following looks right for the uplink port?
BPDU keeps slamming the port when I try to bring up 2950-4. Looks like I need to port the config to GNS3 and test.

Please see below. I was wrong about 2 and 3. The physical layout should be as following.

What do you mean by "BPDU keeps slamming the port when I try to bring up 2950-4."?
You don't have any loops and all you're doing is connecting a switch to a port on the ASA. It doesn't get much easier than this.

ASKER
The switchport in C2950-4 went to error disable with BDP error when I try to bring it up.
cdp neighbor doesn't show router ...... I missed one link to the ASA, By looking the port description in C2950-2 and ASA. I think this should be physical layout. (Apologize for the confusion) Would this leg to the ASA causing aloop?
Is there a way to spill out verbose log of what is causing the loop from STP?

It's impossible to say for certain without a more detailed understanding of your network, but I can almost guarantee that you should not have BPDU guard enabled on the switch 4 ports connecting to any other network devices (switches, ASA).
ASKER
I can provide any log except C2950-4 as the port is shut and I have no console access until tomorrow. Would that help?
The picture above should provide the complete topology .

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
There is more to this than a diagram. For example, where is the root bridge. I'm assuming it's not switch 4. So you do not want BPDU guard on that switch.
As long as you have BPDU guard enabled on that switch, the port will go err-disable within 2 seconds of connecting it.

Thanks. I verified the links between between the switch have no bpdu guard and portfast.
Once I removed bpdu on switch4 (No devices are connected yet), the link comes up but there are errors. Is it correct that I should only enable BDPU and portfast on access port?

Is it correct that I should only enable BDPU and portfast on access port?
By "BPDU" do you mean BPDU guard? If so, that is correct. Portfast (and other related enhancements) should never be applied to ports which connect to other network devices.
The error you're receiving is due to a VLAN mis-match on port f0/47. Most likely, the allowed VLANs for the port are not the same as on switch 4 or you have a native VLAN mis-match.
Would need to see the config for that switch to know for sure.

VLAN 100 is in the trunk on ASA 0/2 and so does on C2950-4. (See my previous post)

Minor point: On the ASA, it shows connecting to port "C2950-4-0/48", but you say that it's connected to port 47.
Are you certain that VLAN 100 is correctly defined on the ASA?

Yes sir. It was a typo in the label.

Does the following matter? switch 1-3 are using vlan 1. Literally vlan 1 is the same 100 but I would like to migrate off vlan 1 for best practice.

Literally vlan 1 is the same 100 but I would like to migrate off vlan 1 for best practice.I'm not sure what you're trying to say here, but 1 and 100 are not the same thing. You may be using them as the same thing, but they are most certainly not the same.
That said, you're going to want to have the same approach on all the switches. Otherwise, it's just going to confuse the issue.

This setup was done by someone long time and will be replaced by vlan 100 with the exact same subnet and ip address. I am curious if the messages can be ignored in the meantime?

I made the change over the weekend (Can't make the change during business hours) on the ASA / switch and the error went away.
It is a requirement on setting native vlan the same on all the trunk ports in ASA, when one of them is have native vlan set?

Mar 16 20:24:36: %SPANTREE-2-UNBLOCK_CONSIST_PORT: Unblocking FastEthernet0/47 on VLAN0100. Port consistency restored.
It is a requirement on setting native vlan the same on all the trunk ports in ASA,No. The native VLAN only has to match both ends of a trunk.

Thanks. Going to swap the switch this weekend!
