buffer-profile global [1Q|4Q]
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.
Example of a Single Queue Application with Default Packet Pointers

buffer dedicated queue0 3 queue1 3 queue2 3 queue3 3 queue4 3 queue5 3 queue6 3
queue7 3
buffer dynamic 1256

Troubleshooting Packet Loss
The show hardware stack-unit command is intended primarily to troubleshoot packet loss.
To troubleshoot packet loss, use the following commands.
•
show hardware stack-unit 0–5 cpu data-plane statistics
•
show hardware stack-unit 0–5 cpu party-bus statistics
•
show hardware stack-unit 0-5 drops unit 0-0 port 1–56
•
show hardware stack-unit 0-5 stack-port 33–56
•
show hardware stack-unit 0-5 unit 0-0 {counters | details | port-stats
[detail] | register | ipmc-replication | table-dump}:
•
show hardware {layer2| layer3} {eg acl |in acl} stack-unit 0-5 port-set 0-0
•
show hardware layer3 qos stack-unit 0-5 port-set 0-0
•
show hardware system-flow layer2 stack-unit 0-5 port-set 0-1 [counters]
•
clear hardware stack-unit 0-5 counters
•
clear hardware stack-unit 0-5 unit 0–0 counters
•
clear hardware stack-unit 0-5 cpu data-plane statistics
•
clear hardware stack-unit 0-5 cpu party-bus statistics
•
clear hardware stack-unit 0-5 stack-port 33–56
