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

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

The following table describes common CPU processes.

Process Name

Process Description

VIDL

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

SOCK

Packet receiving and processing task. If this task has a high CPU usage, the CPU is receiving and processing a large number of protocol packets. If this occurs, the device may be undergoing 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. If this occurs, the device may be undergoing a packet attack.

bcmRX

Bottom-layer packet receiving task. This task has a high CPU usage when the CPU receives a large number of packets.

AGNT

IPv4 SNMP protocol stack task. This task has a high CPU usage when network management operations are frequently performed.

AGT6

IPv6 SNMP protocol stack task. This task has a high CPU usage when network management operations are frequently performed.

SFPM

Optical module management task. This task has a high CPU usage when the system is frequently querying and detecting optical module information.

ROUT

Route management task. This task has a high CPU usage when the system is learning a large number of routes or many routes flap. If 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.
