LACP issue

[jkay18041]

I've got 4 switch stacks setup in a hub and spoke. Each spoke has a LACP connection using 2 fiber connections to the hub. I seem to be having an issue where my monitoring VM can't see certain devices even though they are online and can be pinged from other devices. It only seems to be with one specific type of device (Ruckus AP). I've replaced the fiber, transceivers and even a switch and still no luck. If I unplug one of the LACP pairs it works, but once I plug it back in I loose connection.

Any advice? They are Cisco 3750e switches running 12.2

[balaji.bandi]

Can you post the configuration and how the device connected each other.

how is your Port-channel Loadbalance config ?

[jkay18041]

Here is the config on one of the switches.

interface Port-channel3
description MDF to Server Rack
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 2,3,10,20,63
switchport mode trunk
no vtp

I'm not sure about a load balance config or how to check that.

[balaji.bandi]

i would prefer to see both the switch full config to understand, and give us what port connection you removed to resolve the issue.

Here is switch 1, I've turned tengigabit 1/0/1 to fix the issue

Hi,

   Activate the port, leave it for like 1 minute and post the output of, from both sides of the channel, so from both switches: (make sure to use the proper ports, not sure about the port numbers on the other side)

show lacp neighbor

show lacp interface port-channel 3

show lacp interface TenGigabit1/0/1

show lacp interface TenGigabit1/0/2

show eherchannel summary

show eherchannel 3 detail

show spanning-tree vlan x (x is the VLAN with the AP)

Regards,

Cristian Matei.

Hi,

     I see nothing suspicious. I would recommend an upgrade of IOS code on both sides. But before that, have you tried moving that etherchannel to PAgP or even on mode, to see if the same issues comes up? This way, we isolate the issue being LACP/PAgP for whatever reason.

Regards,

Cristian Matei.

So I have both ends set to LACP mode active, what other mode should I change it to?

If I change to PAgP will I need to modify anything on STP? I've never used PAgP so not sure if it's much different than LACP or not.

Thanks for the help

[Cristian Matei]

Hi,

   No need for any changes in STP. The difference between LACP and PAgP is not relevant for this setup. Run "channel-group x mode desirable" for PAgP on both sides, or "channel-group mode on" for ON mode on both sides, and see if it works. This process is only to exclude something faulty related to LACP for that channel. Before moving to ON or PAgP, completely remove the Port-Channel and its configuration and ideally use a different Port-Channel number (to avoid further bugs, i've seen bugs related to Port-Channel number, yes).

Regards,

Cristian Matei.

Haven't been able to take down the LACP trunk yet to test PAgP. However this issue is only occurring on one vlan, which happens to be our management vlan.
