View driver-level statistics for the data-plane port on the CPU for the specified stack-unit. It provides insight into the packet types entering the CPU to see whether CPU-bound traffic is internal (IPC traffic) or network control traffic, which the CPU must process. View input and output statistics on the party bus, which carries inter-process communication traffic between CPUs. View the ingress and egress internal packet-drop counters, MAC counters drop, and FP packet drops for the stack unit on per port basis. It assists in identifying the stack unit/port pipe/port that may experience internal drops. View the input and output statistics for a stack-port interface. View the counters in the field processors of the stack unit. View the details of the the FP Devices, and Hi gig ports on the stack-unit. Execute a specified bShell commands from the CLI without going into the bShell. View the Multicast IPMC replication table from the bShell. View the internal statistics for each port-pipe (unit) on per port basis. View the stack-unit internal registers for each port-pipe. View the tables from the bShell through the CLI without going into the bShell. Troubleshooting packet loss The show hardware stack-unit command is intended primarily to troubleshoot packet loss. • show hardware stack-unit cpu data-plane statistics • show hardware stack-unit cpu party-bus statistics • show hardware stack-unit 0-11 drops unit 0-1 port 0-49 • show hardware stack-unit 0-11 stack-port 48-51 • show hardware stack-unit 0-11 unit 0-1 {counters | details | port-stats [detail] | register | execute-shell-cmd | ipmc-replication | table-dump}: • show hardware {layer2| layer3} {e.g. acl |in acl} stack-unit 0-11 port-set 0-1 • show hardware layer3 qos stack-unit 0-7 port-set 0-1 • show hardware ipv6 {e.g.-acl |in-acl} stack-unit 0-11 port-set 0-1 • show hardware system-flow layer2 stack-unit 0-11 port-set 0-1 [counters] • clear hardware stack-unit 0-11 counters S-Series Debugging and Diagnostics | 791
