Aruba 2920 triple Stack Trunk Status

[nettec]

Good morning everybody

I actually have a simple question. I searched the WWW about this, but I didn't find alot of solutions. The ones that I found were not helping me. I have set up a Switch stack with three Aruba 2920 48G switches. Now I want to trunk some ports together for an VMWare esxi enviroment. 

Is it possible to get a view of a single trunk via ssh? Because all I get is the complete view of all trunks with command "show trunk", which not gets me a very clear sight on single trunks:

I tried commands like "show trunk trk6" or "show trunking trk6", nothing worked. 

I would be very thankful for any ideas to this.

Best regards

Cedric

It should.

Via CLI, once entered into the Manager Level (prompt will be a #), with commands like:

• show trunks <port-list> (it shows the Port Trunking status of specified <port-list>, where <port-list> is optional)
• show lacp (it shows data for LACP configured ports, if any <-- if you haven't LACP Port Trunks but only No Protocol Port Trunks the show lacp command is not useful)

Hey Parnassus

Thank you for your reply. I already found this command, but it only shows me if a port is member of a trunk. What I want is to list all members of a trunk. Going throu all ports and see what trunk they are member of is a little bit troublesome.

Is it really possible that there is no command for listing all members of a trunk?

Best regards

It's hard for me to follow your request: I mean, are you working with Static Port Trunking (Non Protocol = No IEEE802.3ad LACP) or what?

If so (and I think - hope not to be wrong here - you're doing thing that way - Non Protocol Port Trunking - if you're playing with VMware ESXi and VSS, that setup requires Non Protocol Port Trunking switch side) then the show trunks command shows exactly what your switch has in terms of Port Trunking, respectively:

• Eight (8) Interfaces 1/15, 1/16, 2/14, 2/15, 2/16, 3/14, 3/15 and 3/16 are all members of Port Trunk group 6 (LAG6, BAGG6, Trk6, call it the way you like...).
• Three (3) Interfaces 1/A1, 2/A1 and 3/A1 are all members of Port Trunk group 60 (LAG60, BAGG60, Trk60, call it the way you like...).
• You have Two (2) Port Trunks actually defined: Trk6 and Trk60.

That's all. Static trunk means non protocol port trunking...so the (more informative) show lacp command will show you nothing because LACP is not used at all in those trunks' definition.

Am I wrong? Have I misunderstood your request?

Have your read the Port Trunking chapter of the HPE ArubaOS-Switch Management and Configuration Guide manual (specifically for your Aruba 2920 WB software branch).

What is the output of show lacp (copy and paste, please)?

What is your stack running configuration (only related to Trk6 or Trk60 and related member interfaces)?

What is your Switch (3 Aruba 2920 switches stacked through backplane stacking) running Firmware version?

Hey Parnassus

Thx for your answer. I apologize as it seems that my explanation was a little missleading.

At the moment there are two trunks configure as you mentioned above. Trk60 are three fibre channel uplinks to the core switch. Trk6 is one esxi Host with 8 interfaces, static trunked on switch side and configured to "route by IP-Hash" on VMware esxi side.

There are a few more trunks coming on this switch, so to keep the overview on all trunks the overall "show trunk" is not what I am searching for.

Now the command you gave me says following, for example:

"Please tell me to which trunk Port 2/14 is assigned"

The command that I am searching for says this, for example:

"Please tell me which ports are member of Trunk Trk6"

I hope I could explain you the difference, as my english is not the best.

Best regards

Hi,

have you tried

sh run | incl trunk

Hey AbeAbe

Thank you for your answer.

The command you mentioned shows following:

sw-stack01# sh run | incl Trk6
untagged
1/1-1/14,1/17-1/48,1/A2,1/B1-1/B2,2/1-2/13,2/17-2/48,2/A2,2/B1-2/B2,3/1-3/13,3/
17-3/48,3/A2,3/B1-3/B2,Trk6,Trk60
spanning-tree Trk6 priority 4
spanning-tree Trk60 priority 4

greetings, Cedric

[AbeAbe]

sure if you are doing it like that.. thats the expected outcome,

but

sh run | incl trunk

gives you something like:

sh run | incl trunk
trunk E1,F1 trk1 trunk
trunk F8 trk2 dt-trunk
trunk A13-A14 trk6 trunk
trunk A15-A16 trk7 trunk
trunk A17-A18 trk8 trunk
trunk F2 trk21 dt-trunk

which is close to what you are looking for....

Just to be informative: the "|" symbol is used to pipe the output of first command (the "show run") as the input for the next one (the "include trunk") which is then able to extract all the lines of the entire configuration which include the word "trunk" (sort of a grep).

[nettec]

Thank you Alex

I already tried that command like this, but it just gives me "invalid input"

Greetings, Cedric

[AbeAbe]

Too bad....

perhaps... not as good but either helpful:

sh int brief | incl Trk5
C3-Trk5 1000SX | No Yes Up 1000FDx NA off 0
C4-Trk5 1000SX | No Yes Up 1000FDx NA off 0
C5-Trk5 1000SX | No Yes Up 1000FDx NA off 0
C6-Trk5 1000SX | No Yes Up 1000FDx NA off 0

but take care it's Trk5 not trk5

Hey Alex

Unfortunately still no luck... The command only shows:

sw-stack01# sh int brief | incl trk6
sw-stack01#

It actually does just nothing...

Thx, Cedric

[AbeAbe · Accepted solution]

ok...

try

sh int brief | incl Trk6

it's important that it is Trk6 not trk6!

example from a 2920 stack:

sw21-2920-3# sh int brief | incl Trk26
1/47-Trk26 1000SX | No Yes Up 1000FDx NA off 0
3/47-Trk26 1000SX | No Yes Up 1000FDx NA off 0

If it's case sensitive...it's case sensitive! ;-).

[nettec]

Good Morning

Yeah I actually knew that, but forgot case sensitivity anyway... :)

That did the trick:

sw-stack01# sh int brief | incl Trk6
1/15-Trk6 100/1000T | No Yes Up 1000FDx MDI off 0
1/16-Trk6 100/1000T | No Yes Up 1000FDx MDIX off 0
1/A1-Trk60 SFP+SR | No Yes Up 10GigFD NA off 0
2/14-Trk6 100/1000T | No Yes Up 1000FDx MDI off 0
2/15-Trk6 100/1000T | No Yes Up 1000FDx MDI off 0
2/16-Trk6 100/1000T | No Yes Up 1000FDx MDI off 0
2/A1-Trk60 SFP+SR | No Yes Up 10GigFD NA off 0
3/14-Trk6 100/1000T | No Yes Up 1000FDx MDI off 0
3/15-Trk6 100/1000T | No Yes Up 1000FDx MDIX off 0
3/16-Trk6 100/1000T | No Yes Up 1000FDx MDI off 0
3/A1-Trk60 SFP+SR | No Yes Up 10GigFD NA off 0

I think it shows Trk60 too because it also begins with a 6, but I can live with that. This was exactly what I was searching for.

Thank you very much you two

Best regards, Cedric
