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-profile fp fsqueue-fp buffer dedicated queue0 3 queue1 3 queue2 3 queue3 3 queue4 3 queue5 3 queue6 3 queue7 3 buffer dynamic 1256 ! buffer-profile fp fsqueue-hig buffer dedicated queue0 3 queue1 3 queue2 3 queue3 3 queue4 3 queue5 3 queue6 3 queue7 3 buffer dynamic 1256 ! buffer fp-uplink stack-unit 0 port-set 0 buffer-policy fsqueue-hig buffer fp-uplink stack-unit 0 port-set 1 buffer-policy fsqueue-hig !

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 Debugging and Diagnostics 281
