Network device of CCM/CUCM can't be blacklisted

[gzalo]

Hi. I'm trying to measure the status of a Cisco Call Manager, using the hardware-health mode. I need to blacklist an interface which is supposed to be down:

[HRDEVICENETWORK_Classes::Cisco::CCM]
hrDeviceDescr: lo
hrDeviceErrors: 0
hrDeviceIndex: 3
hrDeviceStatus: running
hrDeviceType: hrDeviceNetwork
info: hrDeviceNetwork (lo) has status running

[HRDEVICENETWORK_Classes::Cisco::CCM]
hrDeviceDescr: eth0
hrDeviceErrors: 0
hrDeviceIndex: 4
hrDeviceStatus: running
hrDeviceType: hrDeviceNetwork
info: hrDeviceNetwork (eth0) has status running

[HRDEVICENETWORK_Classes::Cisco::CCM]
hrDeviceDescr: eth1
hrDeviceErrors: 0
hrDeviceIndex: 5
hrDeviceStatus: down
hrDeviceType: hrDeviceNetwork
info: hrDeviceNetwork (eth1) has status down

I can't seem to blacklist the down interface, I tried some alternatives such as

--blacklist "HRDEVICENETWORK_Classes:eth1"
--blacklist "HRDEVICENETWORK_Classes::Cisco::CCM"
--blacklist "hrDeviceNetwork:eth1"

and many more, but it doesn't seem to be working. Thanks, Gonzalo
