To monitor and troubleshoot routing, open Firepower Device Manager (FDM) for the device and open the CLI console or log into the device CLI using SSH and use the following commands:
- show route displays the routing table for the data interfaces, including routes for directly-connected networks.
- show ipv6 route displays the IPv6 routing table for the data interfaces, including routes for directly-connected networks.
- show network displays the configuration for the virtual management interface, including the management gateway. Routing through the virtual interface is not handled by the data interface routing table, unless you specify data-interfaces as the management gateway.
- show network-static-routes displays static routes configured for the virtual management interface using the configure network static-routes command. Normally, there will not be any static routes, as the management gateway suffices for management routing in most cases. These routes are not available to traffic on the data interfaces. This command is not available in the CLI console.
