Displaying socket information

Displaying socket information
The following socket information is available from the BP console within the rconsole mode.
• Socket detail in open status
• All sockets in open status
• Socket state information
To access the display command that present this information, you must enter the BP console using
the rconsole command as shown in “Using Rconsole” on page 188.
Displaying socket details in open status
Use the show socket id command in the rconsole mode to display socket detail in open status, as
shown in the following.
ServerIronADX1/1# show socket id 0
Sock Peer Local State rx_q_bytes tx_q_byptes
0000 0.0.0.0: 0 10.10.1.100: 443 LISTEN 00000000 00000000
Syntax: show socket id <HEX>
The <HEX> variable specifies the socket ID number in hexadecimal form of the socket that you
want to display details for.
Displaying all sockets in open status
Use the show socket list command in the rconsole mode to display all sockets in open status, as
shown in the following.
Syntax: show sock list
ServerIronADX# rconsole 1 1
ServerIronADX1/1# show sock lis
Sock Peer Local State rx_q_bytes tx_q_byptes
0000 0.0.0.0:0 10.10.6.10: 443 LISTEN 00000000 00000000
0001 0.10.6.50:3832 10.10.6.10: 443 ESTABLISHED 00000000 00000000
0002 209.157.22.1:80 10.10.6.50:3832 SYN_SENT 00000000 00000000
