Mac Address

[Fabrice35]

Is it possible to add the mac address to each detected equipment?

The mac address is as important as the serial number and is present on the boxes when they are delivered.

This would be very useful!

that's not quite possible. OID for mac address exists but it isn't mandatory. Testing now ... a lot of devices return mac address. Ok, I will add it

[xmacan]

Please test code from actual master branch and let me know

[Fabrice35]

It's good for a single device, not for a stack.

When I query my stack in snmp, I get the individual mac addresses: snmpwalk -v2c -c "***" 10.60.2.70 1.3.6.1.4.1.9.9.500.1.2.1.7

Ideally, it should be added to each device: Name: Switch 1 Description: C9200L-24T-4X MAC address: XX:XX:XX:XX:XX:XX HW revision: V01 FW revision: 0.1 SW revision: Amsterdam 17.03.05 Serial number: **** Model name: C9200L-24T-4X

[xmacan]

ups, my bad. I will fix it soon

[xmacan]

Fixed, please try actual master branch

1.3.6.1.4.1.9.9.500.1.2.1.6 - it is cisco proprietary MIB. I will add it too

[Fabrice35]

This is not good for me. First there are 2 instances of the same mac address, followed by a long list of mac addresses that don't match the devices (I think it's the mac addresses of the interfaces). Also, for my stack of 4 devices, I only have the same mac address listed twice.

I got the wrong CISCO OID. It is 1.3.6.1.4.1.9.9.500.1.2.1.1.7 for my switches But I can't find it for the Nexus...

[Fabrice35]

I think there is another problem for the nexus (N9K for me)

The "HW revision", "Serial number" and "Model name" info is displayed for the "module-1" and for my N9K-C93180YC-EX device. I think it should only relate to the equipment, right?

Also, the revision number "SW revision" is only displayed for the module (when it should be displayed for the equipment).

Name: Module-1 48x10/25G + 6x40/100G Ethernet Module Description: 48x10/25G + 6x40/100G Ethernet Module HW revision: V03 FW revision: 7.0(3)I7(6) SW revision: 7.0(3)I7(6) Serial number: XXXXXXXXXXX Manufact. name: Cisco Systems, Inc. Model name: N9K-C93180YC-EX

Name: N9K-C93180YC-EX Description: N9K-C93180YC-EX HW revision: V03 Serial number: XXXXXXXXXXX Manufact. name: Cisco Systems, Inc. Model name: N9K-C93180YC-EX

It is Entity MIB. Vendor can use this MIB or not. If they use it, they may not use all items, sometimes it is not even possible. So snver is trying read information from this MIB and from some other (vendor specific MIBs - I will add cisco soon).

Maybe another nexus type has more (or less) information, I don't know. Maybe is problem in snver. You can try snmpwalk 1.3.6.1.2.1.47.1.1.1.1.2 and compare result with snver.

The same situation as Entity MIB - maybe for cisco is my MAC adress list useless but for other vendors (HPE, 3com) works fine. There is no common solution for all vendors, so I need add cisco vendor specific oids

[Fabrice35]

ok, thanks. With the display info as img/snver.png, it would be great for my cisco stacks :-) I also have cisco 4500, 9800 and old nexus 5K (yes, we're married to cisco :-|) BB

[xmacan]

@Fabrice35 - do you have any other oid for cisco device which could be useful in snver?

[Fabrice35]

Hi,

Here are the OIDs I found to get the mac addresses:

• C9200 and C2960: 1.3.6.1.4.1.9.9.500.1.2.1.1.7
• C4500 and C9800: 1.3.6.1.2.1.2.2.1.6.1
• Nexus N5K and N9K: 1.3.6.1.2.1.2.2.1.6.151060481

1.3.6.1.2.1.2.2.1.6..... it is EntityMIB and it has been functional before. Added the first one.

Please test actual master branch

[Fabrice35]

ok, it's done. Thank you.

Is it possible to force the check of the information of all the devices?

[xmacan]

It isn't possible to run snver for more devices. I will add it

[Fabrice35]

This is not good for my C9200 and c2960. I get a large list of mac addresses (more than 50). They correspond to each interface and not the device. If I query the oid 1.3.6.1.4.1.9.9.500.1.2.1.1.7 I get a single mac address (or N stacked hardware)

Same thing for C4500 and C9800: In cacti I get more than 200 mac addresses, while a snmpwalk shows me the hardware address: snmpwalk -v2c -c "***" 129.20.4.78 1.3.6.1.2.1.2.2.1.6.1 IF-MIB::ifPhysAddress.1 = Hex-STRING: XX XX XX XX XX XX

This is also the same for the nexus and the oid 1.3.6.1.2.1.2.2.1.6.151060481

Sincerely, BB

[Fabrice35]

Is it possible to add the oid cisco?

Currently, the plugin does not collect the mac addresses of the different devices in a stack.

Example: snmpwalk -v2c -c "r" 10.0.20.14 1.3.6.1.4.1.9.9.500.1.2.1.7 CISCO-SMI::ciscoMgmt.500.1.2.1.1.7.1000 = Hex-STRING: 44 B6 BE ... ... 80 CISCO-SMI::ciscoMgmt.500.1.2.1.7.2000 = Hex-STRING: 44 B6 BE ... ... 00

The second address does not appear in the plugin snver list on cacti.

Kind regards, BB

Yes, you got more addresses, but it is correct for me because all of these addresses belongs to your switch.

The second address does not appear in the plugin snver list on cacti.

Kind regards, BB

ok, I need have a look to the MIBS for the right query for more switches in stack

[xmacan]

please could you send me full output from OID 1.3.6.1.4.1.9.9.500.1.2.1.7? Thank you

[Fabrice35]

Hi,

I sent it to you by email.

In fact, with Cisco, everything is a stack! A single material is a stack of 1 :O

[xmacan]

Please try run SQL query: INSERT INTO plugin_snver_steps (org_id,description,oid,result,method) VALUES (9,'Port mac addr','1.3.6.1.4.1.9.9.500.1.2.1.1.7','.*','walk');

And test it.

[Fabrice35]

It works. I get the right mac address(es) in the "Vendor specific" section.
