Example of NTPv3 Configuration to NTPv4 Migration

Note

Note

This procedure only applies to VSP 8600 Series.

Procedure

  1. Configure a Segmented Management Instance.
    Switch:1(config)#mgmt vlan 10
    Switch:1(mgmt:vlan)#ip address 192.0.2.1/24
    Switch:1(mgmt:vlan)# enable
    

    OR

    Switch:1(config)#mgmt clip 
    Switch:1(mgmt:clip)#ip address 198.51.100.1/32
    Switch:1(mgmt:clip)#enable
    
  2. Configure routing for the Management Instance.

    For the VLAN interface, create a static route to reach the NTP server:

    Switch:1(config)#mgmt vlan 
    Switch:1(mgmt:vlan)#ip route 203.0.113.1/24 next-hop 192.0.2.2 
     
    

    OR for the CLIP interface:

    Switch:1(config)#router ospf
    Switch:1(config-ospf)#redistribute direct 
    Switch:1(config-ospf)#redistribute direct enable 
    Switch:1(config-ospf)#exit
    Switch:1(config)#ip ospf apply redistribute direct
     
    
  3. Verify connectivity between the Management Instance and the NTPv4 server.
    Switch:1(config)#ping 203.0.113.1 mgmt
      
  4. Disable NTP globally.
    Switch:1(config)#no ntp
  5. Change the NTP version.
    Switch:1(config)#ntp version 4
  6. Enable NTP globally.
    Switch:1(config)#ntp
  7. Enable NTP master.
    Switch:1(config)#ntp master
