How to search/Scan Vlan of cisco switch ports

navaidmallick2009 · ‎10-31-2014

Can any one tell me how i can scan/search vlans of cisco switch port through any monitoring tool (orion/solarwinds).

Consider this scenario as i have no access to switch and i want to know below things:

1-Vlans created on switch?

2-which switch port belongs to which vlan id?

Thanks

Hi,

You can do it only with hub in between and also please note that when sniffing with Wireshark on Windows the OS would remove VLAN tag so you may need to use Linux machine.

Regards,

Perhaps an OID such as vlanTrunkPortVlansEnabled 1.3.6.1.4.1.9.9.46.1.6.1.1.4 or perhaps dot1dBasePortIfIndex (1.3.6.1.2.1.17.1.4.1.2)

Hope this may help.
