Cisco 3750 stack not reporting MACs on other than commander

[BSHuff]

I have tried standalone cacti and CactiEZ (0.2B) and can not seem to find a way past this. The behavior is the same on both installs.

My central switch in a lab is a 'stackwise' stack of 3 3750s (2X48 port 10/100 & 1 24 port Gig). Mactrack does not detect any of the addresses that are not on the 'commander' of the stack. -So I see Fa1/0/X, but not Fa2/0/X or Gi3/0/X. I am detecting 100+ IP addresses and ports, but only < 48 MAC addresses. I have several other single 3750s around my lab that update fine. The stack is the L3 device for the network.

if I run a php mactrack_scanner.php -d -id=1 I get a bunch of:

PHP Notice: Undefined index: 103 in /var/www/html/plugins/mactrack/lib/mactrack_cisco.php on line 403
PHP Notice: Undefined index: in /var/www/html/plugins/mactrack/lib/mactrack_cisco.php on line 404
PHP Notice: Undefined index: in /var/www/html/plugins/mactrack/lib/mactrack_cisco.php on line 405
towards the end.

attached is a copy of the complete output from the php mactrack_scanner.php -d -id=1 >mactrack.txt

Anyone have input on how to get around this?

Can I test remotely to solve this problem? I am prepping a new release of MacTrack and this feature of 3750's is pretty popular. I would like to address it, but I have not access to hardware.

Hi,

I see this issue is still open,

I have a few stacks of 3750's available.

The Gigabit ones some are showing the same issue.

Switch Ports Model SW Version SW Image
------ ----- ----- ---------- ----------
* 1 52 WS-C3750G-48TS 12.2(25)SEE2 C3750-IPSERVICESK9-M
2 52 WS-C3750G-48TS 12.2(25)SEE2 C3750-IPSERVICESK9-M

In another office with the same stack, but running another IOS version :
Switch Ports Model SW Version SW Image
------ ----- ----- ---------- ----------
1 28 WS-C3750G-24TS-1U 12.2(50)SE3 C3750-IPSERVICESK9-M
* 2 28 WS-C3750G-24TS-1U 12.2(50)SE3 C3750-IPSERVICESK9-M
We don't have the issue, mactrack works fine.


All our 3750 Fastethernet stacks work well with mactrack.

I can give you a remote login to my cacti install, and even to some more if you wish to investigate this ?

Problem is resolved in SVN trunk version of MacTrack.

Thanks,

still had a version from before 6 of july somewhere.

I just installed the latest trunk and did the database upgrade.

Thank you for the quick response.

You're doing a great job.

[JorisFRST]

Ok, all works, but the one stack I have, wich is identical to another stack we have in the company,

so must be down to something I have done on the switches.

1 stack, same IOS as the other, 1 reporting both switches ports, the other only the master in mac track.

i'll try to dig a bit deeper on this...

[JorisFRST]

I can confirm upgrading the one stack to 12.2.50 fixed the issue, mac track started polling all the ports immediately after.

There must be something wrong with the IOS versioin that was on it that didn't work nice with the fibre and copper mix.

Joris.

Good to know.

[TheWitness]

MrRat. Did this solve your issue?

TheWitness

[MrRat]

Not sure yet, trying to schedule a downtime to upgrade a switch to test.

[MrRat]

No , the upgrade to Version 12.2(50)SE3 made no difference.

[TheWitness]

Please follow my other instructions then.

[mariejones]

i followed your instructions and everything is ok now, thanx

Wondering what instructions were provided to Mr Rat/Mariejones. I have a handful of 3750 stacks. They all run the same IOS ((C3750-IPBASEK9-M), Version 12.2(25)SEE2).
The PoE stacks (WS-C3750G-48PS) do not report active MACs. The Non PoE stacks are working correctly (WS-C3750G-48TS). I would like to know if there is something I can do to fix this. I can attach results of PHP mactrack_scanner.php -ID=device_ID -d for a working vs non working stack if that helps
