This command can be used on both the MP and the LP modules. On the LP module, thiscommand displays brief counters only for a specific LP module. The following example outputdisplays the total number of packet statistics that are processed and dropped on module 4 andmodule 7 on the MP.Brocade# show lp-cpu packet statistics briefMODULE 4--------Packets processed: 1000Packets dropped: 200MODULE 7--------Packets processed: 236076Packets dropped: 194163show lp-cpu packet statistics protocolSyntax: show lp-cpu packet statistics protocol [l2 | l3] [ | ]• l2 - Displays Layer 2 protocol packet counters received by the LP CPU.• l3 - Displays Layer 3 protocol packet counters received by the LP CPU.• - Displays protocol packet statistics for an individual port.• - Displays protocol packet statistics for all ports on the LP.This command displays Layer 2 or Layer 3 protocol packets received on a specific slot port, or for allports on the LP. This command can be used on both the MP and the LP, and the output display isthe same for both types of modules when Layer 2 or Layer 3 protocol counters are displayed.The following example output displays Layer 2 protocol packet counters received by the LP CPU onport 4/1 on the MP.358 Brocade MLX Series and Brocade NetIron XMR Diagnostic Guide53-1002426-02
