Configuring Telnet Access To The Switch - Extreme Networks ExtremeWare XOS Guide Manual

Managing the Switch
NOTE
As a general rule, when configuring any IP addresses for the switch, you can express a subnet mask by using
dotted decimal notation or by using classless inter domain routing notation (CIDR). CIDR uses a forward slash
plus the number of bits in the subnet mask. Using CIDR notation, the command identical to the previous
example is: configure vlan default ipaddress 123.45.67.8/24
6 Configure the default route for the switch using the following command:
configure iproute add default <gateway> {vr <vrname>} {<metric>} {multicast-only |
unicast-only}
For example:
configure iproute add default 123.45.67.1
7 Save your configuration changes so that they will be in effect after the next switch reboot.
If you want to save your changes to the currently booted configuration, use the following
■
command:
save
ExtremeWare XOS allows you to select or create a configuration file name of your choice to save
■
the configuration to. If you want to save your changes to an existing or new configuration file,
use the following command:
save configuration
8 When you are finished using the facility, log out of the switch by typing:
or
logout

Configuring Telnet Access to the Switch

By default, Telnet services are enabled on the switch and all virtual routers listen for incoming Telnet
requests. Beginning with ExtremeWare XOS 11.2, the switch accepts IPv6 connections.
NOTE
The BlackDiamond 8800 family of switches and the Summit X450 switch do not support user-created virtual
routers.
ExtremeWare XOS 11.2 introduces the concept of safe defaults mode. Safe defaults mode runs an
interactive script that allows you to enable or disable SNMP, Telnet, and switch ports. When you set up
your switch for the first time, you must connect to the console port to access the switch. After logging
in to the switch, you enter safe defaults mode. Although SNMP, Telnet, and switch ports are enabled by
default, the script prompts you to confirm those settings.
If you choose to keep the default setting for Telnet—the default setting is enabled—the switch returns
the following interactive script:
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 SNMP public and private strings
* consider using SNMPv3 to secure network management traffic
