Using Telnet
A Telnet connection offers the convenience of accessing the switch from any workstation connected
to an interface port. Telnet access provides the same options for user access and administrator
access as those available through the console port.
To configure the switch for Telnet access, the switch must have an IP address. The switch can get its
IP address in one of two ways:
 Dynamically, from a DHCP server on your network (available only for IP interface 1)
 Manually, when you configure the switch IP address
Once you have configured the switch with an IP address and gateway, you can access the switch
from any workstation connected to the management network. Telnet access provides the same
options for user and administrator access as those available through the console port.
By default, Telnet access is enabled. Use the following command to disable/enable Telnet access:
To establish a Telnet connection to the switch, you can run the Telnet program on your workstation
and issue the Telnet command, followed by the switch IP address:
BOOTP Relay Agent
BOOTP Relay Agent Overview
The G8000 can function as a Bootstrap Protocol relay agent, enabling the switch to forward a client
request for an IP address up to two BOOTP servers with IP addresses that have been configured on
the switch.
When a switch receives a BOOTP request from a BOOTP client requesting an IP address, the
switch acts as a proxy for the client. The request is then forwarded as a UDP Unicast MAC layer
message to two BOOTP servers whose IP addresses are configured on the switch. The servers
respond to the switch with a Unicast reply that contains the default gateway and IP address for the
client. The switch then forwards this reply back to the client.
