We have a Firepower Management Centre 2000 appliance (i.e. FS2000-K9) running 188.8.131.52 (build 57) software.
Currently we have the FMC appliance managed via it's eth0 interface i.e. physical NIC "1".
We have a request for the FMC appliance to be also manageable from a second subnet.
The question is, can the FMC appliance be managed by two interfaces? i.e. if we configure eth1 (physical NIC "2") with an IP address which is on a different subnet to the IP address which eth0 is allocated, will that work? is it a supported configuration?
I have research this online and looked through documentation on the Cisco Support Portal but cannot find it clearly stated anywhere that this will proposed configuration will work, or is a Cisco supported configuration, or if there are any banana skins lurking around to slip up on here.
If any of you have already done this and proven it to work, would appreciate your feedback.
As per document you can do this, but i didn't do this kind of configuration anywhere.
The following example shows the Firepower Management Center and managed devices using only the default management interfaces.
The following example shows the Firepower Management Center using separate management interfaces for devices; and each managed device using 1 management interface.
The following example shows the Firepower Management Center and managed devices using a separate event interface.
The following example shows a mix of multiple management interfaces and a separate event interface on the Firepower Management Center and a mix of managed devices using a separate event interface, or using a single management interface.
I think you can enable eth1 interface and assign IP then add the static route to your desired network.
For the record, have proven this work in our lab, with an FMC 4000 appliance (rather than an FMC 2000) under the following setup:
- Physical NIC “1” (logical interface “eth0”) – ORIGINAL interface connected to subnet/VLAN X
- Physical NIC “M” (CIMC/LOM) – ORIGINAL interface connected to subnet/VLAN X
- Physical NIC “2” (logical interface “eth1”) – NEW interface connected to subnet/VLAN Y
