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

Hello,

I am a new Network Admin and I have come into a fully Aruba enviorment. Controller, Switches, APs, ClearPass, and Airwave are all installed here. However, there is no network diagram to speak of, so short of tracing out each cable, I'm not sure where everything is going. 

 

I know in my training with Cisco I was able to use a Show CDP neighbor command to build a network diagram, is there something similar on the Aruba Switches?

 

Show neighbor-devices seems to show all the APs connected, but not the stacked switches or the link between the two stacks we have. I don't believe show cdp neighbors worked for stacked switches either, because it is seen as one large switch.  Is there a way to determine which stack ports are are used between each switch and where other switches are connected between eachother?

 

Also, the stacked switches are all on seperate floors which is why tracing out the cable would be a challenge.

Do you have LLDP enabled on all interfaces / links between your stacks?

I believe so. If I do a show lldp neighbor it shows the APs that are connected as well, but not the links between switches.  I just assumed it was on by default.

ereader22,

To see the stack topology you can use the following commands:

 

(S3500) #show stacking members

Stack status: Active, Stack Id: 001a1e17b98050f9e894
Stack uptime: 61 days 6 hours 17 minutes 1 seconds
Id    Role       MAC Address        Priority  State     Model            Serial
--    ----       -----------        --------  -----     -----            ------
0  *  Primary    00:1a:1e:17:b9:80  Preset    Active    ArubaS3500-24F   BW0000044
1     Secondary  00:0b:86:6c:25:00  Preset    Active    ArubaS3500-48P   AW0000549
2     Linecard   00:0b:86:6b:7b:c0  Preset    Active    ArubaS3500-48P   AW0000446

(S3500) #show stacking topology

Member-id  Role       Mac Address          Interface  Neighbor Member-id
---------  ----       -----------          ---------  ------------------
0  *       Primary    00:1a:1e:17:b9:80    stack1/2   1
                                           stack1/3   2
1          Secondary  00:0b:86:6c:25:00    stack1/3   0
                                           stack1/2   2
2          Linecard   00:0b:86:6b:7b:c0    stack1/2   0
                                           stack1/3   1

 

So what this shows is that the primary switch has a stack link going from its 1/2 (3rd port on the uplink) to member 1 and a stack link going from its 1/3 (4th port on the uplink) to member 2.

 

Now in terms on non-stack switch to switch links, those you would see via LLDP if the profile was attached to those links. Please send over the output of "show interface-config gigabitethernet <x/y/z>" for your switch to switch links and we'll see what's going on with LLDP.

 

Best regards,

Show stacking members is exactly what I needed for that portion. Thank you!  Below is the output for one of the ports I know for sure is an uplink.

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

Alright, so this side of the switch has an LLDP profle:

 

Interface LLDP Profile lldp-factory-initial default

 

And its the factory default so unless someone changed the settings, it whould be sending and receiving LLDP. You can check this by using 'show interface-profile lldp-profile lldp-factory-initial'.

 

Now the question is how is the upstream switch configured. If it doesn't have LLDP enabled on its end, you obviously won't see it. Since you're buidling the network diagram, can you at least log into all your switches and verify that the above is configured?

 

Best regards,

 

Madani

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

I edited my above reply to add in the output from our other switch stack. It's possible that the interface 2/1/0 is causing the issue because it doesn't claim to be factory default. 

 

Is there any issues I should be aware of by running factory default lldp? I'm not sure why it would be changed on just the 1 single port. 

Aruba

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

Yes, there is quite a difference between the two, the default has LLDP disabled.

 

(S1500-1) #show interface-profile lldp-profile lldp-factory-initial

LLDP Profile "lldp-factory-initial"
-----------------------------------
Parameter                               Value
---------                               -----
LLDP pdu transmit                       Enabled
LLDP protocol receive processing        Enabled
LLDP transmit interval (Secs)           30
LLDP transmit hold multiplier           4
LLDP fast transmit interval (Secs)      1
LLDP fast transmit counter              4
LLDP-MED protocol                       Enabled
Control proprietary neighbor discovery  Disabled

(S1500-1) #show interface-profile lldp-profile default

LLDP Profile "default"
----------------------
Parameter                               Value
---------                               -----
LLDP pdu transmit                       Disabled
LLDP protocol receive processing        Disabled
LLDP transmit interval (Secs)           30
LLDP transmit hold multiplier           4
LLDP fast transmit interval (Secs)      1
LLDP fast transmit counter              4
LLDP-MED protocol                       Disabled
Control proprietary neighbor discovery  Disabled

 

So on the uplinks that have the default lldp-profile, apply the lldp-factory-initial.

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

So I configured the port with the lldp factory default profile, it still doesn't appear to show the connected switch stack, though I can be almost certain that it's connected to that port. The issue I think now has to do with the Config Derivation, it's set to N/A. I'm not familiar with how to set that. I used this command to set the profile. 

 

(config)# interface gigabitethernet  2/1/0

lldp-profile lldp-factory-initial

 

 

This is what the interface config currently displays.

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

You don't need to worry about the config derivation as it applies to which interface-group the config was derived from, since you've applied the command specifically on to the interface that takes precedence. However there are other things that are now standing out such as the fact that the switched profile is set to default. Is it possible to attach the 'show tech-support' for this switch? It will give a much better picture of the configuration.
