Active DHCP Leases OID

[jjiles]

Is there an OID to pull the active dhcp leases on a Cat3750 running c3750-ipbasek9-mz.122-46.SE.bin? We are running dhcp server in this switch on one of our remote sites and I would like to graph the data.

I looked online and there is a mib under .1.3.6.1.4.1.9.10. Which is the experimental brunch of Cisco. This MIB it is not supported on the IOS mentioned above.

Thanks for any info.

You can use the following:

CISCO-DHCP-SNOOPING-MIB

http://tools.cisco.com/Support/SNMP/do/BrowseMIB.do?local=en&step=2&mibName=CISCO-DHCP-SNOOPING-MIB

1.3.6.1.4.1.9.9.380.1.4.1.1

The above requires that you enable dhcp snooping:

ip dhcp snooping

ip dhcp snooping vlan  

From the cli, its the same as "sh ip dhcp snooping binding" output.

The CISCO-MAC-NOTIFICATION-MIB should get the dhcp based users info based on mac address, vlan, and ip address.

ciscoMacNotificationMIB

1.3.6.1.4.1.9.9.215

Let me know if it works or not.
