HTTP Access to CMS
To configure the switch for Telnet access, follow these steps:
HTTP Access to CMS
CMS uses Hypertext Transfer Protocol (HTTP), which is an in-band form of communication with the
switch through any one of its Ethernet ports and that allows switch management from a standard web
browser. The default HTTP port is 80.
If you change the HTTP port, you must include the new port number when you enter the IP address in
the browser Location or Address field (for example, http://10.1.126.45:184 where 184 is the new HTTP
port number).
Note The HTTP Port option on CMS is not available if your access level to the switch is read-only. For more
information about the read-only access mode, see the“Access Modes in CMS” sectiononpage2-31.
Do not disable or otherwise misconfigure the port through which your management station is
communicating with the switch. You might want to write down the port number to which your station is
connected. Make changes to the switch IP information with care.
Note The HTTP Port option on CMS is not available if your access level to the switch is read-only. For more
information about the read-only access mode see the “Access Modes in CMS” sectiononpage2-31.
Refer to these topics in the release notes for information about accessing CMS:

• Running the setup program, which includes assigning a privilege-level 15 password for accessing
CMS
• Installing the required Java plug-in
