No MAC adress table with Cisco switches
-
Hello together,
I have a problem getting connected mac-adresses for the ports of my Cisco switches. This occures on different models and software-releases.
CDP isn't activated at ports conected to enduser systems.
Same problems occure in my production environment with version 2.0.5 and my testenvironment with version 2.2.16.
As my production environment has old software implemented and I have to migrate the next weeks lets concentrate on version 2.2.16.
The switches are Cat 3850, 3650, 2960, 4500, 6500 and Nexus n5k.
Within NETxms I only see the MAC-Adresses of the peersystems when CDP is enabled on the interface. It seems that the Mac address table can not be read for the other systems.
Drivers for the systems are CISCO-GENERIC and CATLYST-Generic.
Is there a possibility detecting MAC-adresses for the endsystem ports without activating CDP on these ports at the switch so that they are searchable via tools?
Best regards
Georg
