buffer-profile csf csqueue • Change the dedicated buffers on a physical 1G interface. BUFFER PROFILE mode buffer dedicated • Change the maximum number of dynamic buffers an interface can request. BUFFER PROFILE mode buffer dynamic • Change the number of packet-pointers per queue. BUFFER PROFILE mode buffer packet-pointers • Apply the buffer profile to a line card. CONFIGURATION mode buffer fp-uplink linecard • Apply the buffer profile to a CSF to FP link. CONFIGURATION mode buffer csf linecard Examples of Viewing Buffer Information Dell Networking OS Behavior: If you attempt to apply a buffer profile to a non-existent port-pipe, Dell Networking OS displays the following message: %DIFFSERV-2DSA_BUFF_CARVING_INVALID_PORT_SET: Invalid FP port-set 2 for linecard 2. Valid range of port-set is . However, the configuration still appears in the running-config. Configuration changes take effect immediately and appear in the running configuration. Because under normal conditions all ports do not require the maximum allocation, the configured dynamic allocations can exceed the actual amount of available memory; this allocation is called oversubscription. If you choose to oversubscribe the dynamic allocation, a burst of traffic on one interface might prevent other interfaces from receiving the configured dynamic allocation, which causes packet loss. You cannot allocate more than the available memory for the dedicated buffers. If the system determines that the sum of the configured dedicated buffers allocated to the queues is more than the total available memory, the configuration is rejected, returning a syslog message similar to the following: 00:04:20: %S50N:0 %DIFFSERV-2-DSA_DEVICE_BUFFER_UNAVAILABLE: Unable to allocate dedicated buffers for stack-unit 0, port pipe 0, egress port 25 due to unavailability of cells. Dell Networking OS Behavior: When you remove a buffer-profile using the no buffer-profile [fp | csf] command from CONFIGURATION mode, the buffer-profile name still appears in the output of the show buffer-profile [detail | summary] command. After a line card reset, the buffer profile correctly returns to the default values, but the profile name remains. Remove it from the show bufferprofile [detail | summary] command output by entering no buffer [fp-uplink |csf] linecard port-set buffer-policy from CONFIGURATION mode and no buffer-policy from INTERFACE mode. To display the allocations for any buffer profile, use the show commands. 1068 S-Series Debugging and Diagnostics
