NETGEAR 8800 Chassis Switch CLI Manual Syntax Description This command has no arguments or variables. Default Enabled. Usage Guidelines Enables the switch to use the timestamp IP option (0x44). When the switch receives an IP packet with the timestamp option turned on, it inserts the timestamp into the IP options header before forwarding the packet to the destination. Example The following command enables processing of the record timestamp IP option: enable ip-option record-timestamp enable ip-option strict-source-route enable ip-option strict-source-route Description Enables processing of the strict source route IP option in the IPv4 packet header. Syntax Description This command has no arguments or variables. Default Enabled. Usage Guidelines This enables the switch to forward IP packets that have the strict source route IP option (0x89) enabled. Source routing is used when a sending host specifies the router interfaces that the packet must traverse on it's way to it's destination. When strict source routing is used, it means that the packet must use the exact path of routers that lie in the designated router path. With strict source routing enabled, the switch forwards IP packets with the strict source route option enabled, only if the switch's IP is in the designated list and as long as the next hop in the list is directly attached to one of the router's interfaces.
