vsx-sync dhcpv6-server


vsx-sync dhcpv6-server

no vsx-sync dhcpv6-server


Enables VSX synchronization of all DHCPv6 server configurations, including external storage configurations, on the primary VSX node to the secondary peer. To synchronize DHCPv6 server configurations associated with a particular VRF, configure the same VRF on the peer device.

The no form of the command disables VSX synchronization of DHCPv6 server configurations to the secondary peer; however, it does not remove the existing DHCPv6 server feature configurations from the secondary peer.

Command context



Administrators or local user group members with execution rights for this command.


The first six lines in the following example show the setting of a DHCPv6 server configuration. The last two lines of the example show the enabling of VSX synchronization for global DHCPv6 server configurations.

switch(config)# dhcpv6-server external-storage dhcpv6-dbs file dhcpv6_lease_file delay 600
switch(config)# dhcpv6-server vrf default
switch(config-dhcp-server)# pool test
switch(config-dhcpv6-server-pool)# range 2001::1 2001::10 prefix-len 64
switch(config-dhcpv6-server-pool)# option 22 ipv6 2001::12
switch(config-dhcpv6-server-pool)# static-bind ipv6 2001::11 client-id 1:0:a0:24:ab:fb:9c
switch(config)# vsx
switch(config-vsx)# vsx-sync dhcpv6-server

Disabling VSX synchronization for global DHCPv6 server configurations:

switch(config)# vsx
switch(config-vsx)# no vsx-sync dhcpv6-server
