How does ftd add static routes in ctl and configure priorities?

Translator

My ftd can't connect to fmc because of routing reasons, now I need to add a static route and make the configuration priority higher than ospf

Does the management traffic for the FTDs pass through FTD-B ?  If yes, instead of an any any rule right now, I suggest doing a packet tracer first. One with source of FMC and destination of FTD mgmt IP and destination port of tcp/8305.  Then also in the reverse direction FTD mgmt IP to FMC with destination port of tcp/8305.

If you are looking for technical support I suggest contacting your local Cisco partner, or if you are able to open a TAC case directly then you can do so.

I've tried in fmc ping  FTD  Three are available but only 172.17.2.10 display is disabled.

FMC 172.16.1.31FMC 172.16.1.31FMC 172.16.1.31FTD-B 172.17.2.11FTD-B 172.17.2.11FTD-B 172.17.2.11FTD-SX 172.16.2.251FTD-SX 172.16.2.251FTD-SX 172.16.2.251FTD-A 172.17.2.10FTD-A 172.17.2.10FTD-A 172.17.2.10

The FTD devices reach out to the FMC out of their management ports. It could be that the FTD-A is not configured with the right gateway? you can check that with the command "show network" from the > mode (CLISH mode) on the FTD. If the gateway is correct, it could be related to some firewall in the middle between the FTD devices and the FMC? if you have a firewall, that firewall should allow the FTD traffic between the FTD and the FMC on port 8305/tcp, that is bidirectional, from the FTD to the FMC and vice-versa.

How to use the command to add an any any policy on a FTD that cannot be controlled by FMC

You need to identify the route that management traffic is taking between FMC and FTD.

Are the two FTDs in HA pair?

Is management traffic being routed through a data interface on the FTD that is having issues?

Or, is traffic being routed through the other FTD that is not having issues?

can you ping the FTD from 172.17.3.254 to 172.17.2.10 (the gateway that mgmt traffic is using)?

You can add an ACL entry using the commands I posted earlier, just change the configuration from routing to access-list.  If this solves the issue you will need to add the correct access rule in the FMC before you deploy or the configuration will be overwritten.

1. I can use the gateway on my core switch to ping ftd-A or FMC
Ping -a 172.17.3.254 172.17.2.10

Ping -a 172.17.3.254 172.16.1.31


2. Whether forcing a refresh of the HA status will cause such effects as a device reboot.
How to Manually Refresh on the FTD CLI to Detect the Availability of HA Status.


FTD-A
ping system 172.16.1.31 (FMC) OK
FTD-B

FTD-B

FMC (172.16.1.31) ping FTD-A -B (172.17.2.10, 172.17.2.11) returns normally.

It seems that the 172.16.1.254 does not know how to get back to the FTD-A IP address? Please share your L1/L3 topology diagram for review.

Since you are able to ping from FMC to both FTD, communication is there.  Has the FTD or FMC been replaced? is that how this issue happened?

could you run the command "sftunnel-status" on FTD-A.  This is done from the > prompt

You might also want to try restarting the sftunnel on FTD-A
