 Enter the ID of a task, with the value ranging from 1 to 100.

Enter the ID of a socket, with the value ranging from 0 to 3072.

Use the 

command to display the information about the 

sockets in the current system.

To display the information about the socket of TCP type, enter the following:

<4500>display ip socket socktype 1

Table 14   Output Description of the 

Command

SOCK_STREAM

The socket type

Task

The ID of a task

socketid

The ID of a socket

Proto

The protocol number used by the socket

sndbuf

The sending buffer size of the socket

rcvbuf

The receiving buffer size of the socket

sb_cc

The current data size in the sending buffer. The value makes sense 
only for the socket of TCP type, because only TCP is able to cache 
data

rb_cc

The current data size in the receiving buffer

socket option

The option of the socket

socket state

The state of the socket
