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, as shown in the following
example.

Troubleshooting Packet Loss

The show hardware stack-unit commands are 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 0-7 drops unit 0-5 port 0-49
•
show hardware stack-unit 0-7 unit 0-5 {counters | details | port-stats
[detail] | register | execute-shell-cmd | ipmc-replication | table-dump}:
•
show hardware {layer2| layer3} {e.g. acl |in acl} stack-unit 0-7 port-set 0-5
•
show hardware layer3 qos stack-unit 0-7 port-set 0-5
•
show hardware ipv6 {e.g.-acl |in-acl} stack-unit 0-7 port-set 0-5
•
show hardware system-flow layer2 stack-unit 0-7 port-set 0-5 [counters]
•
clear hardware stack-unit 0-7 counters
•
clear hardware stack-unit 0-7 unit 0-5 counters
•
