What Do Common CPU Processes Such as VIDL, SOCK, and RPCQ Mean?

VIDL

Idle task. A larger value for this task indicates a lower CPU usage.

SOCK

Packet receiving and processing task. When the CPU is receiving and processing a large number of protocol packets, this task has a high CPU usage. This may indicate that the device is the target of an IP packet attack.

RPCQ

Inter-card communication task. The RPCQ and SOCK tasks can be analyzed together. If the device receives a large number of packets and needs to respond to these packets, the RPCQ task has a high CPU usage. This may indicate that the device is the target of packet attack.

bcmRX/mv_rx

Bottom-layer packet receiving task. When the CPU receives a large number of packets, this task has a high CPU usage.

AGNT

IPv4 SNMP protocol stack task. When network management operations are frequently performed, this task has a high CPU usage.

AGT6

IPv6 SNMP protocol stack task. When network management operations are frequently performed, this task has a high CPU usage.

ROUT

Route management task. When the system is learning a large number of routes or many routes flap, this task has a high CPU usage. When this occurs, view routing information to determine whether the route management module is faulty.

VPR

Packet receiving task. This task receives the packets transmitted through the inter-card CPU data packet channel.
