Note: When configuring the Ethernet switch by Telnet, do not modify the IP
address of it unless necessary, for the modification might terminate the Telnet
connection. By default, after logging on, a Telnet user can access the commands
at Level 0.
Connecting Two Switch 7700 Systems
After you have correctly configured IP address of a VLAN interface for an Ethernet
Switch through the console port (using the ip address command in VLAN
interface view), and have added the port (that connects to a terminal) to this VLAN
(using the port command in VLAN view), you can telnet the Switch 7700 to
another Switch 7700 to carry out the configuration, as shown in Figure 10. The
local end is the Telnet client and the peer is the Telnet server. If the two switches
are located on the same LAN, their IP addressed should be configured on the same
segment or have a route between them.
After you telnet to an Ethernet switch, you can run the telnet command to log in
and configure another Ethernet switch.

the PC to the Switch 7700".
4 Perform the following operations on the Telnet client:
<SW7700> telnet xxxx
(xxxx can be the hostname or IP address of the Telnet Server. If it is the hostname,
the switch shall have the static resolution function.)
5 Enter the preset login password. The Switch 7700 prompt (
