Using Telnet
ExtremeWare XOS 11.0 Concepts Guide 43
The same is true if you use the switch to connect to another host. From the CLI, you must specify the IP
address or host name of the device that you want to connect to. If the host is accessible and you are
allowed access, you may log in.
For more information about using the Telnet client on the switch, see “Connecting to Another Host
Using Telnet” on page 43.
About the Telnet Server
Any workstation with a Telnet facility should be able to communicate with the switch over a TCP/IP
network using VT100 terminal emulation.
Up to eight active Telnet sessions can access the switch concurrently. If you enable the idletimeouts
parameter, the Telnet connection times out after 20 minutes of inactivity. If a connection to a Telnet
session is lost inadvertently, the switch terminates the session within 2 hours.
For information about the Telnet server on the switch, see the following sections:
• Configuring Telnet Access to the Switch on page 45
• Disconnecting a Telnet Session on page 46
Connecting to Another Host Using Telnet
You can Telnet from the current CLI session to another host using the following command:
telnet [<host_name> | <remote_ip>] {vr <vr_name>} {<port>}
If the TCP port number is not specified, the Telnet session defaults to port 23. If the virtual router name
is not specified, the Telnet session defaults to VR-Mgmt (previously VR-0). 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 or DHCP 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 are downloaded automatically. You
can then start managing the switch using this addressing information without further configuration. If
you use a Dynamic Host Configuration Protocol (DHCP) server, make sure DHCP is enabled on the
required VLAN to receive IP configuration information.
You can enable BOOTP or DHCP per VLAN by using the following commands:
enable bootp vlan [<vlan> | all]
enable dhcp vlan [<vlan_name> | all]
