This chapter describes switch configuration using the Command Line Interface.
Note: The Command Line Interface (CLI) can be used to configure the Intelligent Switch Solution from a console attached to the serial port of the switch or from a remote terminal using TELNET. The switch cli uses a simple login authentication mechanism. The authentication is based on a user name and password provided by the user during login. The user ”admin” is created by default with password ”password”.
Note: When the switch is started, the user name and password has to be given at the login prompt to access the CLI shell: ------------------------------------------------- user: admin password: ******** JGSM7224> ------------------------------------------------- The ”user-exec” mode is now set. CLI Command Modes provide a detailed description of the various modes available for the switch.
CLI commands need not be fully typed. The abbreviated forms of CLI commands are also accepted by the switch. For example, commands like show management vlan can be typed as show management vl.
CLI commands are case-insensitive.
CLI commands will be successful only if the dependencies are satisfied for the particular command entered. Appropriate error messages will be displayed if the dependencies are not satisfied.
15
Note: The ethernet type of an interface is determined during System Startup. While configuring interface-specific parameters, its ethernet type needs to be specified correctly.
A fast ethernet interface cannot be configured as a gigabit-ethernet interface and vice-versa.
CLI Command Modes
User EXEC Mode
After logging in to the device, the user is automatically set to the User EXEC mode. In general, the User EXEC commands are used to temporarily change terminal settings, perform basic tests, and list system information.
Command Mode Access Method Prompt Exit Method
User EXEC This is the initial mode to start a session.
JGSM7224> The logout method is used.
Privileged EXEC The User EXEC mode command enable, is used to enter the User EXEC mode.
JGSM7224# To return from the Privileged EXEC mode to the Privileged EXEC mode use the disable command.
Global Configuration The Privileged EXEC mode command configure terminal is used to enter the Global Configuration mode.
JGSM7224(config)# To exit to the Global Configuration mode use the exit command. To exit to the Privileged EXEC mode use the end command.
Interface Configuration
The Global Configuration mode command interface <interface-type> <interface-id> is used to enter the Interface configuration mode.
JGSM7224(config-if)# To exit to the Global Configuration mode use the exit command. To exit to the Privileged EXEC mode use the end command.
VLAN Config The Privileged EXEC mode command vlan database is used to enter the VLAN Config mode.
(JGSM7224)(vlan)# To exit to the Privileged EXEC mode use the exit command.
Command-Line Interface
Privileged EXEC Mode
Since many of the privileged commands set operating parameters, privileged access is password protected to prevent unauthorized use. The password is not displayed on the screen and is case sensitive. The Privileged EXEC mode prompt is the device name followed by the pound (#) sign.
Global Configuration Mode
Global Configuration commands apply to features that affect the system as a whole, to any specific interface.
Interface Configuration Mode
Physical Interface Mode The Physical Interface mode is used to perform interface specific operations. To return to the global configuration mode, use the exit command.
Port Channel Interface Mode The Port Channel Interface mode is used to perform port-channel specific operations. To return to the global configuration mode, use the exit command.
Management VLAN Interface Mode The Management VLAN Interface mode is used to perform L3-IPVLAN specific operations. To return to the global configuration mode, use the exit command.
Tunnel Interface Mode The Tunnel Interface mode is used to perform Tunnel specific operations. To return to the global configuration mode, use the exit command.
VLAN Config Mode
This mode is used to perform VLAN specific operations. To return to the global configuration mode, use the exit command.
Protocol Specific Modes
MSTP Configuration Mode This mode is used to configure the MSTP specific parameters for the switch. The Global configuration mode command spanning tree mst configuration is used to enter the MSTP Configuration mode. The prompt displayed in this mode is (JGSM7224)(config-mst)#.
To return to the global configuration mode, use the exit command.
DHCP Pool Configuration Mode This mode is used to configure the network pool / host configurations of a subnet pool. The Global configuration mode command ip dhcp pool <integer(1-2147483647)> creates a DHCP server address pool and places the user in DHCP pool configuration mode. The prompt seen at this mode is (JGSM7224)(dhcp-config)#.
ACL MAC Configuration Mode The MAC access-list global configuration command creates Layer 2 MAC ACLs, and returns the MACAccess list configuration mode to the user. The Global configuration mode command mac access-list extended <(name(1-31))> is used to enter the ACL MAC Configuration mode and the prompt seen at this mode is (JGSM7224)(config-ext-macl)#.
SNTP Configuration Mode This mode is used to configure the SNTP specific parameters for the switch. The Global configuration mode command sntp configuration is used to enter the SNTP Configuration mode and the prompt seen at this mode is (JGSM7224)(config-sntp)#.

4. System Features
The JGSM7224 switch offers a rich set of system features to a user, such as login services, copying/writing facilities, duplex/negotiation support, and many other capabilities. Some features might have special hardware requirements and others might have special design considerations. The related command links provide overview descriptions of the features and includes specific information to consider when using these features.
CFA (Common Forwarding Agent) is a proprietary module, which acts as a common forwarder of packets between the Network Protocol Module(s), the Data-Link Layer Protocol Layer Module(s), and the Device Drivers. CFA provides central management of the generic parameters of all the interfaces in the system.
login authentication
This command sets the authentication method for user logins and the no form of the command sets the authentication method for user logins to default values..
local - Local username database for authentication.
radius - List of all RADIUS servers for authentication.
tacacs - Terminal Access Controller Access Control System.
Example
------------------------------------------------------------------- JGSM7224(config)# login authentication radius JGSM7224(config)# ------------------------------------------------------------------- Changing login authentication from default to another value may disconnect the telnet session. TACACS is a authentication program used on UNIX / Linux systems, few network routers and other network equipment that allows access to a server or a managing computer to determine if the user attempting to log in has the proper rights or is in the user database.

flowcontrol
This command is used to enable or disable the flow-control for an interface. The first 8 ports must have auto-negotiation enabled before you enable flow-control. The remote device must support flow-control. If flowcontrol send is on for a device and if it detects any congestion at its end, then it notifies the link partner or the remote device of the congestion by sending a pause frame.
Syntax erase { startup-config | backup-config | log1 | log2 | log3 }
If flowcontrol receive is on for the remote device and it receives a pause frame, then it stops sending any data packets. This prevents any loss of data packets during the congestion period.

6. DHCP
DHCP (Dynamic Host Configuration Protocol) allows dynamic configuration of a host computer. When a DHCP client is turned on, it initially does not have an IP address assigned to it. It issues a broadcast message to any DCHP servers which are on the network. An exchange takes place during which the DHCP server assigns an IP address to the client and tells the client certain key network configuration parameters.
Many Internet service providers (ISPs) require that their customers use a DHCP client so the ISP may dynamically assign IP addresses and control other network settings. Another use is for laptop computers which may be connected to more than one network. For example a laptop may be connected to a network in the office and also at home. This is an ideal use for DHCP as the laptop doesn't need to be manually reconfigured for use in the 2 different networks. In this case, there needs to be a DHCP server both on the office network and the home network and the laptop needs a DHCP client.
dhcp client release
This command immediately releases the DHCP lease on the interface specified..
Example
Related Commands
show management vlan - Displays the IP interface statistics and configuration.

debug dhcp client
This command sets the debug level for tracing the DHCP client module. The no form of the command disables the debug level for the DHCP client.
all - All trace messages.
event - Trace management messages.
packets - Packets related messages.
bind - Trace bind messages.
Example
