MacTrack + SNMPv3 and Security contexts

Post by ceyounger »

Has anyone gotten around SNMPv3 security context issues?

SNMPv3 config on router/switch:

Code: Select all

snmp-server group viewers v3 auth read viewConfig
snmp-server view viewConfig internet included
snmp-server view viewConfig mib-2 included
snmp-server view viewConfig system included
snmp-server view viewConfig cisco included
snmp-server view viewConfig snmpMIB included
snmp-server view viewConfig ciscoConfig included
snmp-server view viewConfig ciscoMgmt included
snmp-server view viewConfig ciscoImageMIB included
Output from mactrack_scanner:

It seems that since SNMPv3 requires a context change (ie: vlan-60, vlan-70, etc.) to scan in VLANs MacTrack cannot scan for active ports and MACs with the default context vlan-1. SNMPv2 switches work just fine--in fact, this same switch polls without error with version 2.

I thought that using SNMP options I could populate multiple SNMPv3 contexts--but I cannot add any entries to SNMP options other than sets.

This is very interesting. I just closed a bug and the user confirmed it was working. Are you sure your on 2.9?

EDIT: This can not be the latest version of mactrack_cisco.php

I installed MacTrack from SVN--that is current, right?

So I unTARed 2.9-1 and now I get this when I mactrack_scanner -id=1 -d

Code: Select all

PHP Notice:  Undefined variable: snmp_readstring in /usr/local/cacti-0.8.7g/plugins/mactrack/lib/mactrack_cisco.php on line 356
I don't get the authorizationErrors...but it is not grabbing MACs from the SNMPv3 device.

I can still say its working, using rev 1312 from svn trunk.
Thread starter needs this v3 group config:

Code: Select all

snmp-server group viewers v3 auth match prefix read viewConfig
Maybe we need to match the context prefix ("vlan-") because mactrack is actually using contexts? Never thought about that...

We are using c3560-ipbasek9-mz.122-53.SE2.bin.

Edit: On our older ios switches there is no "match prefix" to use, mactrack doesnt work on these.

Cisco, by abusing the standard, then causes problems with folks who need to use contexts. I'm sure it'll break again soon... With regard to your old IOS switches, what do you mean by 'match prefix'?

That argument is not available to configure even.
For instance, with the older c3560-ipbase-mz.122-44.SE1.bin:

Code: Select all

<hostname>(config)#snmp-server group aef v3 priv ?
  access   specify an access-list associated with this group
  context  specify a context to associate these views for the group
  notify   specify a notify view for the group
  read     specify a read view for the group
  write    specify a write view for the group
  <cr>
And with c3560-ipbasek9-mz.122-53.SE2.bin

Code: Select all

<hostname>(config)#snmp-server group aef v3 priv ?
  access   specify an access-list associated with this group
  context  specify a context to associate these views for the group
  match    context name match criteria
  notify   specify a notify view for the group
  read     specify a read view for the group
  write    specify a write view for the group
  <cr>
I cant actually find a command reference about the "match prefix" command from Cisco, but its there and really works, without it, mactrack fails (for me) :)

For those wondering, I'm still here, but lost in the shadows. Yearning for less bugs. Who want's a Cacti 1.3/2.0? Streams anyone?
