Cisco 6500 Errdisable

I have a Cisco 6513 switch connected over a LACP port channel to a Huawei 9312 swich. The LACP group is 2 10GB fiber optic connections. This link ran fine for 3 months and then started having issues and going into errdisable state.

The errdisable log shows it as a channel-misconfig.
I have now set the 6513 to recover the link automatically after 30 seconds. I tried to turn off detection for it, however that is not an option for the particular error.

Below is my configuration for both sides. There are 2 physical ports in the channel. Does anyone have any thoughts that would cause this to suddenly be a problem?

CISCO 6513:
interface Port-channel48
 description URI-COE-SS1-Po48
 switchport
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 13
 switchport mode trunk
 switchport nonegotiate
 load-interval 30
 mls qos trust dscp

interface TenGigabitEthernet13/5
 switchport
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 13
 switchport mode trunk
 switchport nonegotiate
 load-interval 30
 mls qos trust dscp
 channel-group 48 mode active

HUAWEI 9312:
interface Eth-Trunk0
 description MOU-COR-RS1-PO48 SAN
 port link-type trunk
 port trunk allow-pass vlan 13
 mode lacp-static

interface XGigabitEthernet1/0/0

Do you have this command enabled on HUAWEI end?

Can you post the exact error from the log?

Not that it matters that much, but why are you running in trunk mode if you are only allowing a single VLAN?

Because there are two physical interfaces in the Trunk.

I don't have that enabled on the Huawei side

What are the configs for the 2nd ports? Also make sure you're giving us the running configs, not the written configs.

Need to look at the original error as to why it went it error-disable. that message should have a little more detail (I hope) as to what the misconfiguration is.


Port-channels by definition should have multiple ports.  However there is no requirement to have them in trunk mode.  If you have a single VLAN you can make them access mode with VLAN id of 13.  The only reason to have them in trunk mode is if you have multiple VLAN's you want to go over those ports.  Based on your configuration currently you only allow a single VLAN so there is no technical reason why you need them in trunk mode.

That's all I get in the log for an error.

Also, it must be in a trunk because of it talking from Cisco to Huawei across multiple links.

Just to clarify: On the Cisco side at least, it does not have to be in trunk mode in order to use multiple links. that's called a port channel in Cisco-speak, but on other platforms including HP, it is sometimes called trunking.

I know nothing about HUAWEI but I think that the problem is a difference in configured operation between the 2 sides. This could be as simple as a difference in default settings such as port-channel type (LACP vs. PAgP) or the native VLAN for the trunk (VLAN 1 on cisco, could be something else on the HUAWEI).

One thing I'm concerned about is the fact that the HUAWEI is configured to statically use LACP while the Cisco side is not. They should be set the same way- to aither assume LACP and its parameters, or to negotiate those parameters.

I'm currently looking into the option to make the Huawei side an Access port on the Ethernet trunk. However, that would only help on this link.,.. I do have another set of links that carry multiple VLANS.

As far as setting the static LACP on the cisco side, what needs to be changed?

--> "channel-group 48 mode active"

The option active:

LACP mode that places a port into an active negotiating state, in which the port initiates negotiations with other ports by sending LACP packets.

You said it ran fine for 3 months and then started having problems.  Did ANYTHING change the day it starting having problems?  I new switch in the network that could be creating a loop?

Not that I can think of. VLAN 13 for my network is SAN traffic.

So each of the two switches has a Bladecenter connected to it along with several Lefthand Nodes. That's the only place VLAN 13 exists. I think I did find a way to configure the huawei side of the link as access ports which may help alleviate the problem.

However, I'll soon have to do a trunk port that does carry multiple VLANs across it, so I would still like to find a solution.

Instead of mode Active, should I try mode on?

As my understanding, Huawei is must to have "bpdu enable" for LACP.

I don't  think the problem has to do with having this in Trunk mode.  It was just something I saw.

Something has to have changed.  You may not know about it.  Example:  A config change was made to the running config 3 months ago to get this to work, but nobody did a "write mem" to save it.  Then the switch was restarted, reverting back to the non-working config.

Stupid question.  After you reset everything how long do the ports stay up and working?

We never did find a solution for it besides to have errdisable recovery turned on and reenable the ports after 30 seconds. My real solution is replacing all of the equipment mentioned above with Nexus switches. Thanks for the assistance!
