Chapter 9 Switch Operating Procedures
Managing Telnet Access Features
Note
You must enter values for all command parameters, even if you want to change only one of them.
Table 9-27 describes the parameters for this command.
Step 4 To verify your configuration change, enter the dspxbarmgmt command.
Managing Telnet Access Features
The Cisco MGX switches include Telnet client and server software. The Telnet server software allows
you to establish CLI management sessions with a switch using a Telnet client. The Telnet client software
allows you to log into a switch and then establish a Telnet session with another switch.
Starting with Release 5, you can disable the Telnet feature to force users to use secure sessions to access
the switch. The following sections describe how to start Telnet sessions from workstations and switches
and how to enable or disable Telnet access.
Tip
For instructions on establishing secure CLI management sessions from a workstation, see “Starting a
Secure (SSH) CLI Session” in Appendix C, “Supporting and Using Additional CLI Access Options.”
For instructions on establishing secure CLI management sessions between switches, see “ Starting and
Managing Secure (SSH) Access Sessions Between Switches ,” which appears later in this chapter.
Table 9-27 Command Parameters for cnfxbarmgmt
Parameter Description
loadSharing Enables or disables load sharing. Enter -1, 0, or 1. These values control load
sharing as follows:
• -1 unconditionally disables load sharing, regardless of switch plane status
•
0 disables load sharing only when there are no switch plane alarms
• 1 enables load sharing
If you do not want to change the setting, enter the value that corresponds to the
current setting displayed with the dspxbarmgmt command.
autoShutdown Enables or disables the Auto Shutdown feature. Enter 0 to disable this feature,
or enter 1 to automatically shut down a failed link between a switch plane and
a card slot.
If you do not want to change the setting, enter the value that corresponds to the
current setting displayed with the dspxbarmgmt command.
planeAlarmThresh Defines when a switch plane should be reported as bad. Set the threshold to the
number of failed links (between a switch plane and the card slots it services)
that exceeds your acceptable limit. The default threshold is 3. The PXM card
supports up to 14 links.
If you do not want to change the setting, enter the value that appears when you
enter the dspxbarmgmt command.
