xStack DES-3800 Series Layer 3 Stackable Fast Ethernet Managed Switch CLI Manual config vrrp ipif Purpose Syntax Description Parameters Restrictions To configure the authentication type for the VRRP routers of an IP interface. config vrrp ipif [authtype [none | simple authdata | ip authdata ] This command is used to set the authentication type for the VRRP routers of an IP interface. ipif - Enter the name of a previously configured IP interface for which to configure the VRRP entry. This IP interface must be assigned to a VLAN on the Switch. authtype - Specifies the type of authentication used. The authtype must be consistent with all routers participating within the VRRP group. The user may choose between: • none - Entering this parameter indicates that VRRP protocol exchanges will not be authenticated. • simple authdata - This parameter, along with an alphanumeric string of no more than eight characters, to set a simple password for comparing VRRP message packets received by a router. If the two passwords are not exactly the same, the packet will be dropped. ip authdata - This parameter will require the user to set an alphanumeric authentication string of no more than 16 characters to generate a MD5 message digest for authentication in comparing VRRP messages received by the router. If the two values are inconsistent, the packet will be dropped. Only Administrator or Operator-level users can issue this command.
