NETGEAR 8800 Chassis Switch CLI Manual gw_address seconds number vrname Specifies the gateway router IP address of the multicast router to which the unicast mtrace query is sent. Specifies a maximum time to wait for the mtrace response before making the next attempt. The range is 1 to 30 seconds. Specifies the maximum number of hops for the trace. The range is 1 to 255. Specifies a VR name. Default destination: IP address of interface from which mtrace query is generated. group: 0.0.0.0 from: IP address of interface from which mtrace query is generated. gateway: 224.0.0.2 when the destination is in the same subnet as one of the IP interfaces. For a non-local destination address, it is mandatory to provide a valid multicast router address. timeout: 3 seconds maximum-hops: 32 vr: DefaultVR Usage Guidelines The multicast traceroute initiator node generates a multicast query and waits for timeout period to expire. If there is no response for the timeout period, the initiator node makes 2 more attempts. If no response is received after 3 attempts, the initiator node moves to a hop-by-hop trace by manipulating the maximum hop fields to perform a linear search. The multicast trace response data contains the following fields: • Incoming interface address-Interface on which traffic is expected from the specific source and group • Outgoing interface address-Interface on which traffic is forwarded from the specified source and group towards the destination • Previous hop router address • Input packet count on incoming interface • Output packet count on outgoing interface • Total number of packets for this source-group pair • Multicast routing protocol • Forwarding code NETGEAR switches set the packet count statistics field to 0xffffffff to indicate that this field is not supported.
