dell powerconnect and mactrack

[gary2006]

I have mactrack running in our setup ... however, it seems that Dell switches are not correctly giving information on mac addressing on user ports using generic_switch_ports template.

I suspect that this function needs to be modified to accommodate dell switches.

I have attached snmp walk output ... however, I am bit lacking in what needs to be changed for this.

Any assistance is appreciated.

Thanks

more info ... with generica switch_ports function, it seems we are unable to get vlan's identified and we are pulling default vlan 1 addressing.

I will appreciate help on deciphering SNMP strings or update needed for this function.

You need to drop your dell MIB files into your net-snmp mibs directory and then set an environment variable called MIBS to the special keyword ALL and then run again. Without that change, it's a difficult read.

Hi TheWitness,

Here is Take 2 on snmpwalk with Dell MIBs loaded.

I see some of the items have description now attached as opposed to generic SNMPv2 strings.

I used 34xx series mibs to match the switch type ... hope, this is what you were looking for.

Thanks for your attention and time to this.

NSL. Here are your VLAN Names. Until you get your MIB's to work showing things like ..."VLAN_Name"... or something like that, it will be difficult.

Once you have that listing working correctly, send me the walk again as both named and numeric OID's.

Hi TheWitness,

Somehow -- I could not get this to work with net-snmp ... however, it worked with NuDesign's MIB browser ... may be it could load MIBS with dependencies etc.

Here is walk on 1.3.6.1.2.1 tree ... names are now getting converted into description for dot1q vlans.

I suspect that you would need few more of such mappings ... if that's so, let me know.

Thanks

Instead of associating your switch with "getGenericSwichPorts", associate it wit "getGenericDot1QSwitchPorts" and see what happens

TheWitness

[gary2006]

Ummm .. seems that we may be getting close.

I do not have that function ... I searched for latest SVN posted in one of the forums with 07/10/2006 date ... and under mactrack_fucntions ==> it only has generic_switch_ports and generic_wireless_ports listed.

So, can you point me or post latest file with generic_dot1q stuff, please?

[TheWitness]

Crap. I hope I published it. Will look into it.

TheWitness

[TheWitness]

You are correct. It is a simple matter of code. I will address before release.

TheWitness

[gary2006]

Thanks, TheWitness.

I would anxiously be waiting for it to try out.

[gary2006]

TheWitness,

Thanks for "genericDot1q switch port" function ... however, it did not work.

"genericSwitchports" was giving me all MAC addresses from default vlan 1.

From my struggle, I tried to modify HP function ... so, following query gets me # of vlans.

/* get VLAN information */
$vlan_ids = xform_standard_indexed_data(".1.3.6.1.2.1.17.7.1.4.2.1.3", $device);

/* get VLAN Trunk status */
$vlan_trunkstatus = xform_standard_indexed_data(".1.3.6.1.2.1.17.7.1.4.2.1.6", $device);
$device["vlans_total"] = sizeof($vlan_ids);
mactrack_debug("VLAN data collected. There are " . (sizeof($vlan_ids)) . " VLANS.");

Above query returns ---> There are XX vlans.

However, it would seem that following is where I am having trouble with ...

/* get the port status information */
$port_results = get_base_dot1dTpFdbEntry_ports($site, $device, $ifInterfaces, "", "", FALSE);
$port_vlan_data = xform_standard_indexed_data(".1.3.6.1.2.1.17.7.1.4.5.1.1", $device);


I have attached visual SNMP walk on dot1Q portion of the tree .. if it helps.

[TheWitness]

Could you get the tree's in net-snmp in both numeric oid format and text oid format and e-mail to me. Just to be clear:

Numeric .1.3.6.xxx

Text .iso.something....vlanname

I work much better from that type of list.

Thanks,

TheWitness

[gary2006]

Attached are numerical and descriptive SNMPwalks.

Following is sample from dot1Q trunk:

Q-BRIDGE-MIB::dot1qVlanStaticName.2 = STRING: VLAN 2
Q-BRIDGE-MIB::dot1qVlanStaticName.3 = STRING: VLAN 3
Q-BRIDGE-MIB::dot1qVlanStaticName.4 = STRING: VLAN 4
Q-BRIDGE-MIB::dot1qVlanStaticName.5 = STRING: test 5


SNMPv2-SMI::mib-2.17.7.1.4.3.1.1.2 = STRING: "A VLAN"
SNMPv2-SMI::mib-2.17.7.1.4.3.1.1.3 = STRING: "W VLAN"
SNMPv2-SMI::mib-2.17.7.1.4.3.1.1.4 = STRING: "E VLAN"
SNMPv2-SMI::mib-2.17.7.1.4.3.1.1.5 = STRING: "t"

BTW, I did get some errors running SNMPwalk as I loaded whole bunch of MIBS ... and some may not have proper dependency (or so I think).

Let me know if this looks unusual and I will work on removing thsoe errors on net-SNMP.
Thanks again for your attention to this.

Hi,

We are deploying some Dell PowerConnect 6248's in our infrastructure and I have yet to get MacTrack to work with them. Are there any new functions available which will successfully query these switches?

Thanks,

Shawn
