[FC] MacTrack on 3Com Switches

[gilles184]

Hi everyone,

i've tried to make Mactrack working with 3com switch.

first of all, i'm not a php developper so be kind

for this i've copied get_dot1dTpFdbEntry_ports and get_base_dot1dTpFdbEntry_ports form mactrack_functions.php into
mactrack_3com.php
and modify them renamed as get_3Com_dot1dTpFdbEntry_ports and
get_3Com_base_dot1dTpFdbEntry_ports

i do this because i didn't want to modify mactrack_functions.php and :

1) 3Com 1100 have IfName empty so it is not possible to use "Ports to Ignore"

3Com 1100 have ifDescr instead but names use this format : "RMON:Vx Port Y on Unit z"
as you can see it is not realy simple and use ":" in it which will makes "Ports to Ignore" unusable.
So this script check for IfDescr if IfName are empty
transform it to "PortN/M" where N is stack unit an M port Number
In this way you can specify port to ignore as "PortN/M"
this is true for 3com 1100 and 42xx

2) 3Com 5500 have IfType 117 (Gigabit Ethernet)

Macktrack check IfType as >=6 and <=9
i've just added || == 117

NB: my linux print snmp enums as text so i'v edited /etc/snmp/snmp.conf and added "printNumericEnums 1"

3) in get_base_dot1dTpFdbEntry_ports "Ports to Ignore" looks useless
"if (!in_array($port_number, $ignore_ports)" compare portname to portnumber ?
(Again i'm not a developper so maybe i miss something).


So to use It copy attached file in :
<cactidir>/plugins/mactrack/lib
edit <cactidir>/plugins/mactrack/lib/mactrack_vendors.php
and add

Code: Select all

include_once($config["base_path"] . "/plugins/mactrack/lib/mactrack_3com.php");

then in cacti : Tracking Utilities -> Refresh Scanning Functions


this have been tested on 3com : 1100 4200 4900 and 5500


NB: these switches have 802.1Q but 3com seems to use special mib tree and code mac address in binary in oid as index so i didn't investigate this way too much. (too much headhache:) )

Any comments welcome.

Gilles.

PS: my english is not as good as it shoud be sorry...

Your scripts work fine:)

Has anyone got this to work so mactrack get's the VLAN# from the 3com switches to?

Gilles,

I have added this script to the 2.0 development. Thanks for your contribution.

I figured out that the script doesn't update neither the "mac_track_interfaces" table with the new "ifName" values nor the "mac_track_interface_graps" table, because your function "complete_3com_ifName()" is called after "build_InterfacesTable()". So the bug which result is that, in the interface tab of mactrack, we can't see the graph which is normally associated with an interface.
So I modified your function, I hope you don't mind, here is my file "mactrack_3com.php". You can now see correctly the associated graphs. Hope it will work for everyone else.

Cool, thanks. Sending upstream.

Hi,
i'm configuring mactrack 2.9 for someone switches (Cisco 3750,6509,HP Procurve& 3Com 3870/4400) and is all ok; working fine
But now i have serious problem to configure this plugin for 3Com 4500 ( switches L2/L3)
This is very important for me and my society because i am deployment this mactrack control plugin for about 600 3Com 4500 switches and
i am trying this configuration but without success.
Nothing happen in Device Tracking - MAC to IP Report View and and nothing in Device Tracking - ARP/IP View
This is the configuration
[*]Switch/Router
[*]Vendor snmp Object ID Match -->.1.3.6.1.4.1.43
[*]MAC Address Scanning Function--->get_3com_dot1d
[*]IP Address Scanning Function --->get_standard_arp_table
[*]Serial Number Base OID --->.1.3.6.1.4.1.43.1.16.4.3.31
[*]Serial Number Collection Method
[*] Lw/Hig port ---> 0

Can you help me ?? have you some documentation about this plugin ??
thank

Try this. This is modified version of mactrack_3com.php script. You need to place it in <mactrack plugin>/lib directory and add a corresponding entry to <mactrack plugin>/lib/mactrack_vendors.php file.

For me, this version works less or more reliably with 3Com 4500/5500/4500G/4200G/5500G and H3C S3600 switches, but it better than nothing.

AFAIR here I added support for dot1q vlans and fixed some incompatibility with switches listed above. Also I removed support for older 3Com interface name remapping.

really, how many times can I say THANK YOU ?!?!?!
