Persistence Commands
persistence
Syntax [no] persistence
Context config>system
Description This command enables the context to configure persistence parameters on the system.
The persistence feature enables state on information learned through DHCP snooping across reboots to be
retained. This information includes data such as the IP address and MAC binding information, lease-length
information, and ingress sap information (required for VPLS snooping to identify the ingress interface).
If persistence is enabled when there are no DHCP relay or snooping commands enabled, it will simply create
an empty file.
Default no persistence
dhcp-server
Syntax dhcp-server
Context config>system>persistence
Description This command configures DHCP server persistence parameters.
subscriber-mgmt
Syntax subscriber-mgmt
Context config>system>persistence
Description This command configures subscriber management persistence parameters.
