10LP CPU packet statisticsdebug iptunnel tunnel-typeSyntax: [no] debug iptunnel tunnel-type [gre | ipv6] [range - ]You can specify the type of tunnel to debug. The valid options are gre for GRE tunnels and ipv6 forIPv6 tunnels. Within a specified range of tunnels, information is filtered for the tunnel type if it isconfigured. If a tunnel type is not configured, debug messages are printed based on range only.The no debug iptunnel tunnel-type command resets the previously configured tunnel type (if any),and prints messages for tunnels within the specified range.LP CPU packet statisticsProtocol control packets and data packets are forwarded to the Line Processor Central ProcessingUnit (LP CPU) for packet processing. The LP CPU forwards the packets to a destination port or theForwarding ID (FID), and the packet is either sent to the Management Processor (MP) module forprocessing, or the packet is dropped based on the forwarding decision. At various stages of the LPCPU packet processing, packet counters are maintained to assist with debugging.NOTELP CPU packet statistics are maintained after MP switchover.NOTELP CPU packet statistics are reset to zero after hitless upgrade and LP reboot.LP CPU packet statistics show commandThis section describes the show commands that display LP CPU packet information.show lp-cpu packet statisticsSyntax: show lp-cpu packet statisticsThis command displays the total number of packets that are received, dropped, forwarded, orflooded by the LP CPU during packet processing. For packets that are dropped, packet drop causesare indicated in the output display. This command also displays the number of packets processedby the LP CPU received from Layer 2, Layer 3, MPLS uplinks, VPLS, and other data packets. The LPcounters are text-wrapped to zero on the CLI. The LP CPU counters are not cleared after you displaypacket statistics using the show lp-cpu packet statistics command. The LP CPU counters aredisplayed on both the MP and the LP.The following counters are not displayed on the CLI using the show lp-cpu packet statisticscommand:• PBIF RX or TX packet counters• XPP and TM packet counters• MP or LP IPC packet counters• Packets originated by the MP or LP.NOTEThe show lp-cpu packet statistics command displays statistics for packets that are received bythe LP CPU from hardware only.350 Brocade MLX Series and Brocade NetIron XMR Diagnostic Guide53-1002426-02
LP CPU packet statistics 10This command can be used on both the MP and LP modules. On the LP module, the show lp-cpupacket statistics command displays LP CPU counters only for a specific LP module. The followingexample output displays the total number of packets received by the LP CPU from MPLS, VPLS, VLL,ARP, and other data packets on module 4.Brocade# show lp-cpu packet statisticsMODULE 4----------Total Packets Received: 1000MPLS uplink packets received: 0VPLS packets received:0VLL packets received: 0L3 VPN packets received:0Other MPLS packets received:0ARP packets received:0ARP response packets received:0ARP request packets received:0IPV4 packets received:0IPv4 unicast packets routed:0IPv4 protocol packets received:0GRE tunnel packets received:06to4 tunnel packets received:0IPV6 packets received:0IPv6 unicast packets routed:0Ipv6 protocol packets received:0IPv4 multicast packets routed:0IPv6 multicast packets routed:0L2VPN endpoint packets received:0VPLS endpoint packets received:0VLL endpoint packets received:0Local-VLL endpoint packets received:0L2 packets received:1000L2 known unicast packets forwarded:600L2 unknown unicast packets flooded:100L2 broadcast Packets flooded:100L2 multicast Packets flooded:0Packets received for SA learning:0Other packets received:0Total Packets dropped:200Packet drop causes:[PP – Post Processing Drops; CV – Configuration Violation Drops;PE - Packet Error Drops; PFE - Potential Forwarding Error Drops;OD - Other Drops]3-L2 packet forwarded in hardware(PP):10020-L2 port state is blocking(CV):100ARP packets captured for DAI:0ARP packets failed DAI:0Table 6 displays the descriptions of the fields from the show lp-cpu packet statistics command.Brocade MLX Series and Brocade NetIron XMR Diagnostic Guide 35153-1002426-02
