the remote TCP, or an acknowledgment of the connection
termination request previously sent.
ˆ FIN-WAIT-2 - Waiting for a connection termination request from the
remote TCP.
ˆ CLOSE-WAIT - Waiting for a connection termination request from
the local user.
ˆ CLOSING - Waiting for a connection termination request
acknowledgment from the remote TCP.
ˆ LAST-ACK - Waiting for an acknowledgment of the connection
termination request previously sent to the remote TCP which
includes an acknowledgment of its connection termination request.
ˆ TIME-WAIT - Waiting for enough time to pass to be sure the
remote TCP received an acknowledgment of its connection
termination request.
ˆ CLOSED - No connection.
The entries for the listening sockets for the Telnet, SSH, and web
browser servers are identified in the table with a TCP state of LISTEN.
If you disable a server on the switch, its corresponding LISTEN entry is
removed from the table. Disabling all the servers leaves the table
empty. (The SSH server is disabled by default on the switch.)
The example in Figure 54 on page 172 shows that the Telnet and web
browser servers are active on the switch. The table also includes two
active TCP connections. Entry 4 is for a Telnet connection and entry 24
is for a web browser HTTP connection.
A web browser management session can have more than one TCP
connection open at a time. The different connections are used to carry
different packets of the management session.
You cannot change any of the information in this table. The only
operating parameter on the switch that affects management TCP
connections that you can adjust, other than enabling or disabling the
servers, is the TCP port used by the web browser server. The default
values are port 80 for HTTP and 443 for HTTPS. For instructions on
how to change this setting, refer to “Configuring the Web Server” on
page 687. The management software does not allow you to change
the default port number of 23 for Telnet connections or 22 for SSH
connections.
