SNR S2940-8G-v2 Switch Configuration Guide
Basic Switch Configuration
Example of SSH Server Configuration
Example 1:
Requirement: Enable SSH server on the switch, and run SSH2.0 client software such as Se-
cure shell client or putty on the terminal. Log on the switch by using the username and password
from the client.
Configure the IP address, add SSH user and enable SSH service on the switch. SSH2.0 client
can log on the switch by using the username and password to configure the switch.
Switch(config)#ssh-server enable
Switch(config)#interface vlan 1
Switch(Config-if-Vlan1)#ip address 100.100.100.200 255.255.255.0
Switch(Config-if-Vlan1)#exit
Switch(config)#username test privilege 15 password 0 test
In IPv6 networks, the terminal should run SSH client software which support IPv6, such as
putty6. Users should not modify the configuration of the switch except allocating an IPv6 address
for the local host.
2.3 Configure Switch IP Addresses
All Ethernet ports of switch are default to Data Link layer ports and perform layer 2 forwarding.
VLAN interface represent a Layer 3 interface function which can be assigned an IP address, which
is also the IP address of the switch. All VLAN interface related configuration commands can be
configured under VLAN Mode. Switch provides three IP address configuration methods:
• Manual
• BOOTP
• DHCP
Manual configuration of IP address is assign an IP address manually for the switch.
In BOOTP/DHCP mode, the switch operates as a BOOTP/DHCP client, send broadcast pack-
ets of BOOTPRequest to the BOOTP/DHCP servers, and the BOOTP/DHCP servers assign the
address on receiving the request. In addition, switch can act as a DHCP server, and dynamically
assign network parameters such as IP addresses, gateway addresses and DNS server addresses
to DHCP clients DHCP Server configuration is detailed in later chapters.
