The console port connects to the FXOS CLI.

We recommend using the console port. You can also connect using SSH to the management

interface, if configured in the chassis platform settings in the management center; however, if

you change the management IP address, you will be disconnected.

Note

Step 2 Log in with the username admin and the password you set during initial setup.

Step 3 Change the Management IP address. You can use a static IPv4 and/or IPv6 address.

IPv4:

scope fabric-interconnect

set out-of-band static ip ip_address netmask network_mask gw gateway_ip_address

IPv6:

scope fabric-interconnect

scope ipv6-config

set out-of-band static ipv6 ipv6_address ipv6-prefix prefix_length ipv6-gw gateway_address

Example:

IPv4:

firepower-3110# scope fabric-interconnect

firepower-3110 /fabric-interconnect # set out-of-band static ip 10.5.23.8 netmask

255.255.255.0

gw 10.5.23.1

IPv6:

firepower-3110# scope fabric-interconnect

firepower-3110 / fabric-interconnect # scope ipv6-config

firepower-3110 / fabric-interconnect /ipv6-config # set out-of-band static ipv6 2001:DB8::34

ipv6-prefix 64 ipv6-gw 2001:DB8::1

Step 4 Change the management center.

You should first unregister the chassis from the current management center.

enter device-manager manager_name [hostname {hostname | ipv4_address | ipv6_address}] [nat-id nat_id]

You are prompted for the registration key.

You can enter this command from any scope.

• hostname {hostname | ipv4_address | ipv6_address}—Specifies either the FQDN or IP address of the

management center. At least one of the devices, either the management center or the chassis, must have

a reachable IP address to establish the two-way, TLS-1.3-encrypted communication channel between

the two devices. If you do not specify a hostname, then the chassis must have a reachable IP address or

hostname and you must specify the nat-id.

• nat-id nat_id—Specifies a unique, one-time string of your choice that you will also specify on the

management center when you register the chassis when one side does not specify a reachable IP address

or hostname. It is required if you do not specify a hostname, however we recommend that you always
