New 7030 Controller Deployment

Hello Airheads;

 

I've been struggling to setup a new Aruba 7030 in my school enviroment. I've spent the better part of two days on what I'm sure is going to amount to something trivial, but as of yet its not obvious to me.

 

Ultimately I want my controller on my Management VLAN (ex: VLAN-1), my APs on another (VLAN-2), and my users on their own VLAN (VLAN-3). My controller currently has GE0/0/0 connected to my switch, and planned to put this on a untagged VLAN1 port on my switch. GE0/0/4-7 I planned to create an LACP bond with VLAN2-VLAN4  ( I would *like* to have my SSID's on different VLANS to set different rules on my content filter ).

 

Please see the attached diagram. I have decided to start from scratch on a config, so I didn't post that. I am migrating from an Aruba Instant based system consisting of AP-105s.

 

If there is a better way, I'd love to learn.

Re: New 7030 Controller Deployment

Update 1: I now have my controller sorta working the way I want - I can manage it on the management VLAN, it has IPs in different subnets, and actually got it providing a WLAN on the desired VLAN. However, I cannot seem to get any kind of bonding via LACP or Trunk to work..

 

Here is the config from the 7030:

interface gigabitethernet 0/0/4
description "GE0/0/4"
trusted
trusted vlan 1-4094
switchport mode trunk
switchport trunk native vlan 20

And from my HP 5406zl:

( D21-D24 are connected to ports 0/0/4-0/0/7 on the Aruba 7030 )

Re: New 7030 Controller Deployment

Update 2: So, I've given up on making LACP work. I made the 4 ports between the HP 5406zl and the Aruba 7030 into a regular trunk and stacked my VLANs on that.


For my wifi clients, it appears to be working just fine. However, from other hosts on my network, it comes and goes - I can ping the IP of the Aruba 7030 on the VLAN assigned to that trunk, and it just seems to come and go. I'm lost as to why.

 

Here is the updated relevant parts of my configuration:

Re: New 7030 Controller Deployment

Is Spanning Tree running on the 5400 and/or 7030? If so, what does each device show the links between them to be operating as?

 

Are you able to see the LACP trunks on both sides?

 

From what you've described, it sounds like there is either some links in the channel that aren't active, or something causing links to come in and out of service leading to the dropped traffic.

Re: New 7030 Controller Deployment

When I was trying LACP, according to the console on both my switch and my controller, the links were active - I couldn't find any reason they weren't working. 

 

I didn't think of spanning tree, but here is what I have:

Do I need to explictly enable spanning tree on the Aruba for that VLAN?


 

The 7030 shows STP is forwarding on Gig0/0/1, which from your previous documentation I believe is your mgmt interface, correct? It also shows as discarding on the port channel.

 

There might be an STP mismatch here, with the 7030 running RSTP and the 5400 running MST.

Re: New 7030 Controller Deployment

I suspect that what's happening here is that since there is one spanning tree instance, the port channel and the single mgmt interface between the 7030 and 5400 are being treated as a loop, and consequently getting blocked. I would either move the mgmt vlan into the port channel rather than have it as it's own unique interface, or possibly disconnect the mgmt interface for quick testing to see if the port channel transitions to the forwarding state.

Re: New 7030 Controller Deployment

I don't know that I fully grasp the implications of MSTP/RSTP/STP, or in other words, whats involved in switching from MSTP to RSTP, as it appears the Aruba supports just RSTP or RSTP-PVST. 

 

That being said, I have disabled the other interfaces, so now there is just the portchannel-0. However everything appears to be in the discarding state, and I do not know how to change that.

I do believe that you may be correct - that STP may be my issue, but I don't know what I need to do to make the 5406 and the Aruba play nicely. I suppose I could dump the rest of the trunk and just use one interface.... but that seems like a bad solution.

Re: New 7030 Controller Deployment

What happens if you disable STP on the 7030?

Charlie Clemmer

Re: New 7030 Controller Deployment

I will try that... I'm assuming the procedure is as follows?

 

(config) #spanning-tree
(spanning-tree) #no mode
(spanning-tree) #exit

 

Thank you btw
