Using Telnet
ExtremeWare 7.2e Installation and User Guide 49
NOTE
Maximize the Telnet screen so that automatically updating screens display correctly.
To open the Telnet session, you must specify the IP address of the device that you want to manage.
Check the user manual supplied with the Telnet facility if you are unsure of how to do this.
After the connection is established, you will see the switch prompt and you may log in.
Connecting to Another Host Using Telnet
You can Telnet from the current CLI session to another host using the following command:
telnet [<ipaddress> | <hostname>] {<port_number>}
If the TCP port number is not specified, the Telnet session defaults to port 23. Only VT100 emulation is
supported.
Configuring Switch IP Parameters
To manage the switch by way of a Telnet connection or by using an SNMP Network Manager, you must
first configure the switch IP parameters.
Using a BOOTP Server
If you are using IP and you have a Bootstrap Protocol (BOOTP) server set up correctly on your network,
you must provide the following information to the BOOTP server:
• Switch Media Access Control (MAC) address, found on the rear label of the switch
• IP address
• Subnet address mask (optional)
After this is done, the IP address and subnet mask for the switch will be downloaded automatically.
You can then start managing the switch using this addressing information without further
configuration.
You can enable BOOTP on a per-VLAN basis by using the following command:
enable bootp vlan [<vlan name> | all]
By default, BOOTP is enabled on the default VLAN.
If you configure the switch to use BOOTP, the switch IP address is not retained through a power cycle,
even if the configuration has been saved. To retain the IP address through a power cycle, you must
configure the IP address of the VLAN using the command-line interface, Telnet, or web interface.
All VLANs within a switch that are configured to use BOOTP to get their IP address use the same MAC
address. Therefore, if you are using BOOTP relay through a router, the BOOTP server relays packets
based on the gateway portion of the BOOTP packet.
NOTE
For more information on DHCP/BOOTP relay, see Chapter 12.
