Hi Muris,
My suggestion is to upgrade to Netdisco 2. The debugging and troubleshooting options in the new version are much better. 

The process is straightforward:

Hello,

I am trying to run a arpnip/macsuck from Cisco 877's however i am
unable to do so in Netdisco 1.3.
For some reason Cisco 877's do not work with Macsucks and arpnips, and 
show connected hosts. Is there any reason why it should not work on
Cisco 877s? Has anyone come accross this?

I had suggestions to change it from being detected as  Layer3::Cisco
device to Layer3::C3550 or Layer3::C6500 but still dont pickup
anything

Here is a debug of macsuck and arpnip off a 877. Anyone can give any
clue to get the hosts working and displaying as connected devices?
Thanks in advance

Hi Emma,

We have instances where we have a (cisco) phone connected to a port
and then a PC via that phone.  So the port configuration has a
switchport access vlan and a voice vlan.
I do know that Cisco's voice vlan feature is a little funky, but it's a long time since I've looked at how Netdisco handles it. Doesn't surprise me that something isn't right (tho if anyone with similar config reads this and has different output in ND2 - please pipe up, otherwise I assume what Emma reports is standard behaviour). 


Netdisco appears to only
show the data vlan when you look at a switch port vlan membership. Is 
there a known way to get it to show the voice vlan in addition under
VLAN membership?  It does mention the vlan if connected nodes is
selected, you see a phone symbol, its MAC/IP address and in brackets
'on vlan xxx' where xxx is the voice vlan.
So the data comes from two places, which might explain the difference. Associated with the Node is a VLAN that is stored when we do per-VLAN MAC address table retrieval. With the Device Port is associated a set of tagged VLANs and this seems to be missing the voice VLAN - but I suspect the device isn't actually reporting it in the place we're looking.
There's a special table for the voice VLANs, which SNMP::Info (inside Netdisco) supports: vmVoiceVlanId. What I guess the Cisco device class code should do is merge this with the Device Port VLAN table to get the complete picture.
Emma, please can you post the output of this command on one of the devices where you see the issue: 

~netdisco/bin/netdisco-do show -d <IP-of-device> -e i_voice_vlan
Everyone else - please squeak if you think it's a really bad idea to merge vmVoiceVlanId with vlanTrunkPortVlansEnabled* (looks like a bunch of other things are already merged on Cisco anyway, such as dynamic VLANs). I reckon most network engineers would think of the voice VLAN as a tagged VLAN and expect to see it in the VLAN Membership column. 

regards,
oliver.

real quick note:

We're using Aastra phones and NDv2 appears to generally
show the right stuff.  VLAN 2 is the data VLAN, 3005 is the
voice VLAN (see attached pic).
