Sample buffer profile configuration
The two general types of network environments are sustained data transfers and voice/data. Dell
Networking recommends a single-queue approach for data transfers (Figure 57-11).

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 0-0 port 0-63
• show hardware stack-unit 0-11 stack-port 0-63
• 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 0-0
• show hardware layer3 qos stack-unit 0-7 port-set 0-0
• show hardware ipv6 {e.g.-acl |in-acl} stack-unit 0-11 port-set 0-0
• show hardware system-flow layer2 stack-unit 0-11 port-set 0-0 [counters]
• clear hardware stack-unit 0-11 counters
• clear hardware stack-unit 0-11 unit 0-0 counters
• clear hardware stack-unit 0-11 cpu data-plane statistics
• clear hardware stack-unit 0-11 cpu party-bus statistics
• clear hardware stack-unit 0-11 stack-port 0-63
