Check the Cisco DNA Traffic Telemetry Appliance hardware status:
show platform Chassis type: DN-APL-TTA-M Slot Type State Insert time (ago) -------- ------------------- ---------- -------------- 0 DN-APL-TTA-M ok 1w2d 0/0 BUILT-IN-2T+6X1GE ok 1w2d 0/2 NIM-SSD ok 1w2d R0 DN-APL-TTA-M ok, active 1w2d F0 DN-APL-TTA-M ok, active 1w2d P0 ASR1001-X-PWR-AC ps, fail 1w2d P1 ASR1001-X-PWR-AC ok 1w2d P2 DN-APL-TTA-M-FANTRAY ok 1w2d Slot CPLD Version Firmware Version --------- ------------- ---------------- 0 14041015 17.1(1r) R0 14041015 17.1(1r) F0 14041015 17.1(1r)

Check the management and traffic interface status:
show ip interface brief Interface IP-Address OK? Method Status Protocol Te0/0/0 unassigned YES NVRAM up up Te0/0/1 unassigned YES NVRAM up up GigabitEthernet0/0/0 unassigned YES NVRAM up up GigabitEthernet0/0/1 unassigned YES NVRAM up up GigabitEthernet0/0/2 unassigned YES NVRAM up up GigabitEthernet0/0/3 unassigned YES NVRAM up up GigabitEthernet0/0/4 unassigned YES NVRAM up up GigabitEthernet0/0/5 10.56.197.144 YES NVRAM up up GigabitEthernet0 10.56.197.144 YES manual administratively down down

Verify the connectivity to Cisco DNA Center:
ping <Cisco-DNA-Center-IP-address> source gigabitEthernet 0/0/5
Example:
ping 10.56.197.145 source gigabitEthernet 0/0/5 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 10.56.197.145, timeout is 2 seconds: Packet sent with a source address of 10.56.197.144 !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 m

Display the interface statistics:
show interface <interface-name>

Show system information:
show version
The show version command displays the configuration of the system hardware, the software version, and the names and sources of configuration files and the boot images. This command also displays information about how the system was last started and how long the appliance has been running since that start.
The command output is similar to the following:
