DMS-3130 Series Layer 3 Stackable Managed Switch Hardware Installation Guide Connecting to the MGMT Port The front panel of the Switch features an Out-Of-Band (OOB) RJ45 MGMT port which can be used to connect to a computer using a standard Ethernet cable. A web browser or Telnet client can be used to connect to the Switch using the MGMT port. Note: The Telnet method requires a password to log in to the CLI by default. After logging in to the Web UI, go to Management > Login Method. Create a password for telnet in the Login Password section (refer to the following chapter: Web-based Switch Configuration for access through a web browser). To use the MGMT port, connect one end of an Ethernet cable to a computer and the other end to the Switch. The default IP address of the MGMT port is 192.168.0.1 and the subnet mask is 255.255.255.0. Make sure that the computer being used for the switch management has a non-conflicting IP address in the 192.168.0.0/24 network. The following screen should be displayed after a successful connection: To view the IP settings of the MGMT port, use the following command through the console port.: Switch#show ip interface mgmt 0 mgmt_ipif 0 is enabled, Link status is up IP address is 192.168.0.1/24 Gateway is 0.0.0.0 Switch# The IP settings or enabled status of the MGMT port can be changed through the console port. For example, to change the IP address of the MGMT port, use the following commands: Switch#configure terminal Switch(config)#interface mgmt 0 Switch(config-if)#ip address 192.168.1.1 255.255.255.0 Switch(config-if)# Connecting using SNMP The Simple Network Management Protocol (SNMP) is an OSI Layer 7 (Application Layer) protocol designed specifically for managing and monitoring network devices. SNMP enables network management stations to read and modify the settings of gateways, routers, switches, and other network devices. Use SNMP to configure system features for proper operation, monitor performance, and detect potential problems in the Switch, switch group, or network. Managed devices that support SNMP include software (referred to as an agent), which runs locally on the device. A defined set of variables (managed objects) is maintained by the SNMP agent and used to manage the device. These objects are defined in a Management Information Base (MIB), which provides a standard presentation of the information controlled by the on-board SNMP agent. SNMP defines both the format of the MIB specifications and the protocol used to access this information over the network. The Switch supports SNMPv1, SMNPv2c, and SNMPv3. The administrator may specify which SNMP version to use to monitor and control the Switch. The three SNMP versions vary in the level of security provided between the management station and the network device. 38
