Output Fields
Table 1 lists
the output fields for the show services link-services cpu-usage command. Output fields are listed in the approximate order in which
they appear.
Field Name |
Field Description |
Level of Output |
|---|---|---|
Role |
CPU functional category. |
brief |
1 Second Average |
Percentage of usage during 1-second duration. |
All levels |
5 Second Average |
Percentage of usage during 5-second duration. |
All levels |
QoS |
Quality of service (QoS) CPU, which takes care of queuing and scheduling of incoming IP packets on a per-bundle basis. It schedules packets with higher QoS values first. |
All levels |
Sequencer |
Assigns sequence numbers to outgoing MLPPP fragments and interleaves link fragmentation and interleaving (LFI) traffic. |
All levels |
Load Balancer |
Distributes load across different fragmenter CPUs. |
All levels |
Fragmenter |
Main LSQ CPU; fragments IP packets into MLPPP fragments and also reassembles MLPPP fragments into IP packets. |
All levels |
Total |
Sum of all CPU functions. |
brief |
Idle |
Counts idle cycles when the CPU does not have any work. |
detail |
Timer |
Takes care of periodic events driven by a timer, such as timeouts. |
detail |
System |
System housekeeping thread. |
detail |
Input (QoS) |
Acquires and queues incoming IP frames from hardware interfaces. |
detail |
Output (QoS) |
Sends scheduled frames to the next processing CPU. |
detail |
Output Frags (QoS) |
Sends outstanding frames to the fragmenter CPU. |
detail |
Bypass (QoS) |
Sends outstanding frames for LFI. |
detail |
Free frame (QoS) |
Frees dropped frames. |
detail |
CPUnumber |
Identifier number of specific CPU. |
detail |
Drop (Fragmenter) |
Drops frames that have been marked by the QoS CPU. |
detail |
Frag (Fragmenter) |
Fragments IP frames into MLPPP fragments. |
detail |
Reass (Fragmenter) |
Reassembles MLPPP fragments into IP frames. |
detail |
Freeback (Fragmenter) |
Handles freeback of credits from other CPUs (MultiServices PICs only). |
detail |
Input LFI (Sequencer) |
Receives LFI traffic from QoS CPU and transmits it with strict priority over MLPPP. |
detail |
Input Frag (Sequencer) |
Receives MLPPP fragments from fragmenter CPUs, assigns sequence numbers, and appends MLPPP headers. |
detail |
Output Frag (Sequencer) |
Load-balances and transmits fragments across links. |
detail |
Retry (Sequencer) |
Retries transmission if hardware was busy in the previous attempt. |
detail |
Input Alloc (Load Balancer) |
Acquires frames from hardware interfaces and validates them. |
detail |
Input (Load Balancer) |
Performs error and sanity checks and check frames for PortMapping. |
detail |
Output (Load Balancer) |
Sends frame to next processing CPU. |
detail |
Freeback (Load Balancer) |
Handles freeback of credits from other CPUs. |
detail |
