SNR S2940-8G-v2 Switch Configuration Guide
Switch management
1.1.2 In-band Management
In-band management refers to the management by login to the switch using Telnet, or using HTTP,
or using SNMP management software to configure the switch. In-band management enables
management of the switch for some devices attached to the switch. In the case when in-band
management fails due to switch configuration changes, out-of-band management can be used for
configuring and managing the switch.
Management via Telnet
To manage the switch with Telnet, the following conditions should be met:
1. Switch has an IPv4/IPv6 address configured;
2. The host IP address (Telnet client) and the switch's VLAN interface IPv4/IPv6 address is in
the same network segment;
3. If 2) is not met, Telnet client can connect to an IPv4/IPv6 address of the switch via other
devices, such as a router.
The switch is a Layer 2 switch that can be configured with several IP addresses, the configu-
ration method refers to the relative chapter. The following example assumes the shipment status
of the switch where only VLAN1 exists in the system.
The following describes the steps for a Telnet client to connect to the switch's VLAN1 interface
by Telnet(IPV4 address example):
Step 1 : Configure the IP addresses for the switch and start the Telnet Server function on the
switch.
First is the configuration of host IP address. This should be within the same network segment
as the switch VLAN1 interface IP address. Suppose the switch VLAN1 interface IP address is
10.1.128.251/24. Then, a possible host IP address is 10.1.128.252/24. Run
ping 10.1.128.251
from the host and verify the result, check for reasons if ping failed.
The IP address configuration commands for VLAN1 interface are listed below. Before in-band
management, the switch must be configured with an IP address by out-of-band management (i.e.
Console mode), the configuration commands are as follows (All switch configuration prompts are
assumed to be
Switch hereafter if not otherwise specified):
Switch>
Switch>enable
Switch#config
Switch(config)#interface vlan 1
Switch(Config-if-Vlan1)#ip address 10.1.128.251 255.255.255.0
Switch(Config-if-Vlan1)#no shutdown
To enable the Telnet Server function, users should type the CLI command telnet-server enable
in the global mode as below:
Switch>enable
Switch#config
Switch(config)# telnet-server enable
