NETGEAR 8800 Chassis Switch CLI Manual The last column of the mtrace command output displays forwarding codes, which are described in Table 29. Table 29. mtrace Command Forwarding Codes Forwarding Code Description Wrong interface mtrace request arrived on an interface to which this router would not forward for this source and group. Prune sent upstream This router has sent a prune request upstream for the source and group in the mtrace request. Output pruned This router has stopped forwarding for this source and group in response to a prune request from the next hop router. Hit scope boundarya The group is subject to administrative scoping at this hop. No route This router has no route for the source or group and no way to determine a potential route. Wrong Last Hop This router is not the proper last-hop router. Not forwardinga This router is not forwarding for this source and group on the outgoing interface for an unspecified reason. Reached RP/Core Reached rendezvous point or core. RPF Interface mtrace request arrived on the expected RPF interface (upstream interface) for this source and group. Multicast disabled Info. Hiddena mtrace request arrived on an interface which is not enabled for multicast. One or more hops have been hidden from this trace. No space in packet Next router no mtracea There was not enough room to insert another response data block in the packet. The previous hop router does not understand mtrace requests. Admin. Prohibiteda mtrace is administratively prohibited. a. NETGEAR 8800 switches along the mtrace path do not provide this forwarding code. Example The following command initiates an mtrace for group 225.1.1.1 at IP address 1.1.1.100: Switch.6 # mtrace source 1.1.1.100 group 225.1.1.1 Mtrace from 1.1.1.100 to Self via 225.1.1.1 0 34.2.2.4 -1 34.2.2.4 PIM thresh^ 0 1.1.1.100/32 -2 34.2.2.3 PIM thresh^ 0 1.1.1.100/32 -3 23.1.1.2 PIM thresh^ 0 1.1.1.100/32 -4 2.2.2.1 PIM thresh^ 0 1.1.1.100/32 Round trip time 9 ms; total ttl of 4 required.
