Ntp Interface

This scenario restricts where the NTP daemon listens via set system ntp listen local-address|local-interface|local-vrf.

Test NTP Listen Local-Address

Description

DUT0 binds NTP to a specific local address. DUT1 must still synchronize against it.

Scenario

Step 1: Set the following configuration in DUT0 :

set interfaces ethernet eth0 address 10.100.0.50/24
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
set system ntp listen local-address 10.100.0.50
set system ntp master prefer
set system ntp master stratum 3

Step 2: Set the following configuration in DUT1 :

set interfaces ethernet eth0 address 10.100.0.60/24
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 3: Ping IP address 10.100.0.50 from DUT1:

admin@DUT1$ ping 10.100.0.50 count 1 size 56 timeout 1
Show output
PING 10.100.0.50 (10.100.0.50) 56(84) bytes of data.
64 bytes from 10.100.0.50: icmp_seq=1 ttl=64 time=0.339 ms

--- 10.100.0.50 ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.339/0.339/0.339/0.000 ms

Step 4: Run command set date ntp 10.100.0.50 at DUT1 and check if output contains the following tokens:

Date was successfully updated
Show output
Date was successfully updated!

Test NTP Listen Local-Interface

Description

DUT0 binds NTP to a specific interface. DUT1 must still synchronize against it.

Scenario

Step 1: Set the following configuration in DUT0 :

set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
set system ntp listen local-interface eth0
set system ntp master prefer
set system ntp master stratum 3

Step 2: Set the following configuration in DUT1 :

set interfaces ethernet eth0 address 10.100.0.60/24
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 3: Ping IP address 10.100.0.50 from DUT1:

admin@DUT1$ ping 10.100.0.50 count 1 size 56 timeout 1
Show output
PING 10.100.0.50 (10.100.0.50) 56(84) bytes of data.
64 bytes from 10.100.0.50: icmp_seq=1 ttl=64 time=0.681 ms

--- 10.100.0.50 ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.681/0.681/0.681/0.000 ms

Step 4: Run command set date ntp 10.100.0.50 at DUT1 and check if output contains the following tokens:

Date was successfully updated
Show output
Date was successfully updated!

Test NTP Listen Local-VRF

Description

DUT0 binds NTP to interfaces in a VRF. DUT1 must still synchronize against it.

Scenario

Step 1: Set the following configuration in DUT0 :

set interfaces ethernet eth0 address 10.100.0.50/24
set interfaces ethernet eth0 vrf ntp-vrf
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 4: Run command set date ntp 10.100.0.50 at DUT1 and check if output contains the following tokens:

Date was successfully updated
Show output
Date was successfully updated!

Test NTP No Listen Restriction

Description

Without listen, NTP binds everywhere.

Scenario

Step 1: Set the following configuration in DUT0 :

set interfaces ethernet eth0 address 10.100.0.50/24
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
set system ntp master prefer
set system ntp master stratum 3

Step 2: Set the following configuration in DUT1 :

set interfaces ethernet eth0 address 10.100.0.60/24
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
