camSTABrTabDevPort broken?

Hi!

I'm trying to find out what devices are behind our stations, but this OID always is answering "N/A". According the doc:

http://support.cambiumnetworks.com/framed/onlinetools/content.CAMBIUM-PMP80211-MIB.html#camSTABrTabDevPort

Is there a way to know the MAC address connected to the ethernet port?

Thanks in advance!

Hi, 

Which release are you using? We found a problem with the Bridge Table and it is fixed in Release 2.4.1.

Thanks,
Sriram

Hi,

Thanks for your quick answer. I had read the release notes in 2.4.1 and I'm trying with that version.

The snmp answer isn't showing the only mac SM should find connected to the ethernet port. Another problem is with the interfaces. Any of the entries isn't showing a correct value

I have attached two images with an example.

Regards,

Mario.

Hi Mario, 

I have feedback from one of our engineers on this.

The Bridge Table is a table/group in SNMP. Do the following:

Use snmpwalk method to get values from cambiumSTABridgeEntry table:

snmpwalk -v 2c -c public localhost 1.3.6.1.4.1.17713.21.1.2.50.1

OR

Specify indexes for each table cell at the end of snmpget request.

The following is an example from snmpwalk on Release 2.4.1:

root@Cambium-Device:~# snmpwalk -v 2c -c public localhost 1.3.6.1.4.1.17713.21.1
.2.50.1
CAMBIUM-PMP80211-MIB::camSTABrTabBridgeName.1 = STRING: br-lan
CAMBIUM-PMP80211-MIB::camSTABrTabBridgeName.2 = STRING: br-lan
CAMBIUM-PMP80211-MIB::camSTABrTabDevMACAddress.1 = STRING: 00:0C:29:71:1E:9B
CAMBIUM-PMP80211-MIB::camSTABrTabDevMACAddress.2 = STRING: 00:04:56:C3:0C:7D
CAMBIUM-PMP80211-MIB::camSTABrTabDevPort.1 = STRING: LAN
CAMBIUM-PMP80211-MIB::camSTABrTabDevPort.2 = STRING: Own
CAMBIUM-PMP80211-MIB::camSTABrTabAgingTime.1 = Counter32: 106
CAMBIUM-PMP80211-MIB::camSTABrTabAgingTime.2 = Counter32: 0

snmpwalk -v 2c -c public localhost 1.3.6.1.4.1.17713.21.1.2.50.1.2.1

returns correct MAC addresses values from Bridge table.


root@Cambium-Device:~# snmpwalk -v 2c -c public localhost 1.3.6.1.4.1.17713.21.1.2.50.1.2.1
CAMBIUM-PMP80211-MIB::camSTABrTabDevMACAddress.1 = STRING: 00:0C:29:71:1E:9B

Anyway, you are doing the snmp requests to localhost. Is there a way to have access to shell(not the standard cli)? It would be ver useful to execute wget, tcpdump and other unix tools. Thanks in advance

Mario.

Hello Mario,

issue has been already fixed in release 2.4.2.

Thank you.
