Re: How do you find directly connected Aruba Devices in S2500 switch?

Attached you will find a show tech-support.

 

This is the main switch stack in our building. We have 2 switch stacks.

Re: How do you find directly connected Aruba Devices in S2500 switch?

So at least based on the profile names, I don't think 2/1/0 and 3/1/1 are connected to other switches. I think they are connected to a Mobility Controller.

 

!
interface gigabitethernet "2/1/0"
   lldp-profile "lldp-factory-initial"
   lacp-profile "LACP_ToController"

!
interface gigabitethernet "3/1/1"
   lacp-profile "LACP_ToController"
!

The Mobility Controllers do not currently transmit/receive LLDP so you won't see them. How many switches are supposed to be attached to this one? We might have to look at the MAC address table to find ports with large numbers of MACs to track them down.

There is really one 1 switch stack that I'm not sure where it connects in. If those two ports are controllers, then that must leave the third uplink port for the other switch stack. Does that sound reasonable to assume? 

 

Based on this is sounds like 2/1/1 may be the missing link? This raises the question of why didn't it show up as an lldp neighbor though.

Based on the profile name "Tower Access" that definitely leads me to belive that this is the port for access to our other stack, our other stack is called the Tower Stack.

 

So I guess we have found what I needed, but still brought the question to light of why did this link not show in a show lldp neighbor?

Re: How do you find directly connected Aruba Devices in S2500 switch?

Can you attach the techsupport file for that other switch. Let's see how it is configured.

Attached is the show tech support from the other stack. 

 

Thanks for taking the time to look it over.

Re: How do you find directly connected Aruba Devices in S2500 switch?

Puzzling, the config is enabled for lldp (notice the lldp-factory-initial) on the default group. Let's check this, run this command on both stacks:

 

show lldp statistics

 

That way we can see who is and isn't sending LLDP.

Here is the requested info. Sorry for the delay in my response.

 

This is our main stack (seems to be the issue?)

Re: How do you find directly connected Aruba Devices in S2500 switch?

Yeah if the main stack is not giving you any output for "show lldp statistics", something is wrong. On that chassis did you previously say that you could see at least APs in the show neighbor-devices output?

Re: How do you find directly connected Aruba Devices in S2500 switch?

I only tried from the tower stack, which is the one that is showing output. So I'm not sure if it was working. Do you happen to have any idea what might by the cause of not having lldp data?
