Problem: I am using dual server to offer IP address to the extreme mgmt vlan. Ip address is getting assigned. but the tftpserver IP and file name are not used to down load config. Do we need to do any specific configuration to download this config at startup time.

This switch currently has all management methods enabled for convenience reasons.
Please answer these questions about the security settings you would like to use.

Telnet is enabled by default. Telnet is unencrypted and has been the target of
security exploits in the past.

Would you like to disable Telnet? [y/N]: Yes
Disabling telnet access ... done

SNMP access is enabled by default. SNMP uses no encryption, SNMPv3 can be
configured to eliminate this problem.

Would you like to disable SNMP? [y/N]: No

All ports are enabled by default. In some secure applications, it maybe more
desirable for the ports to be turned off.

Would you like unconfigured ports to be turned off by default? [y/N]: No

Changing the default failsafe account username and password is highly
recommended.  If you choose to do so, please remember the username and
password as this information cannot be recovered.
Would you like to change the failsafe account username and password
now? [y/N]: No

Would you like to permit failsafe account access via the management port?
[y/N]: Yes
Enabling failsafe account access via the management port ... telnet ssh

The switch can proactively attempt to send basic configuration and
operational switch information for the purpose of assisting technical
support to resolve customer-reported issues. Uploaded data is encrypted if
the ssh.xmod is installed. Otherwise, a reduced switch data set is sent
in clear text that contains no customer-specific information.

Would you like to disable the automatic switch reporting service?
[Y/n]: No
Enabling the automatic reporting service ... done

Since you have chosen less secure management methods, please remember to
increase the security of your network by taking the following actions:

  * change your admin password
  * change your failsafe account username and password
  * change your SNMP public and private strings
  * consider using SNMPv3 to secure network management traffic
  * install the ssh.xmod
