Persistence Commands
Note: The commands described in this section apply only to the 7450 ESS and 7750 SR.
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
ancp
Syntax ancp
Context config>system>persistence
Description This command configures ANCP persistence parameters.
