Configuring the Management Interface for Remote Access
To manage the switch remotely using Telnet or SNMP you must first configure the
management interface. You can use DHCP to automatically configure the interface
(enabled by default), or you can manually configure the following IP parameters:
 IP address and subnet mask
 Gateway address
For ENOS, the management interface can be remotely accessed using a Web
browser.
By default, DHCP is enabled on the management interface. If there is no DHCP
offer received, the switch uses the default management IP address
(
192.168.50.50/24
). This address is overwritten when a DHCP address is
received for that interface. If DHCP is enabled and there is no static address
configured for DHCP, requests continue to be sent. This feature does not change
existing DHCP functionality.
To configure the management interface for remote management, you can choose
between following two options:
 configure an out-of-band management IP address and a default gateway
 configure an in-band management IP address over a Switch Virtual Interface
(SVI) interface and an associated default gateway (only for CNOS)
After you configure the IP address for your switch and you have an existing
network connection, you can use the Telnet program from an external management
station to access and control the switch. The management station and your switch
must be on the same IP subnet.
The switch CLI allows you to configure and control the switch over the network
using the Telnet program. You can use the CLI to perform many basic network
management functions. In addition, you can configure the switch for management
using an SNMP-based network management system or a web-browser, in the case
of an ENOS switch.
Note: While SSH is enabled by default on the switch, Telnet is disabled. To enable
Telnet, use the following command:
For more information about using the CLI, see the Command Reference guide for
your specific switch and firmware version.
