Hello,
I have Cisco ASA5508-X Threat Defense (75) Version 7.0.2 (Build 88).
Image upgraded without any issues in accordance with this instruction via management interface in "rommon" and "firepower-boot>" modes https://www.cisco.com/c/en/us/support/docs/security/firepower-ngfw/200884-installing-and-upgrading-firepower-threa.html
Then tansparent firewall mode is configured and FTD management interface br1 is configured in accordance with the instruction: https://www.cisco.com/c/en/us/support/docs/security/asa-5500-x-series-firewalls/212420-configure-firepower-threat-defense-ftd.html
configure network ipv4 manual 192.168.11.2 255.255.255.0 192.168.11.1
As, I see, management interface on ASA and on neighboring device is UP (and I tried to use 5 different devices to test - 2 switches, 2 PCs, one router):

But the network doesn't work, no pings response, no ARPs even no any outgoing packets from Cisco ASA management interface:

From what I see in neighboring devices statistics and on packet capture there is literally zero outgoing packets from Cisco ASA management interface.
Please kindly help with this, as I have no ideas what else to do this fix that.

Hello, this is fixed now. The problem was that in rommon register setting was wrong, now this is changed to 0x1 and the system works well.

Do you see the MAC address "C0:14:FE:7E:FE:68" of the FTD on the switch port where it is connected?
09-19-2023 03:02 AM
09-19-2023 03:15 AM
Not really sure then. If you try to disconnect the network cable connected to the management port, does it show the link down?
09-19-2023 05:42 AM
Yes, when I disconnect the cable, this br1 interface goes down.
