Management Interface (VLAN ID)

The name and number of the management VLAN through which the switch will be managed.

The default ID is 1. The default name for the management VLAN is default. The number can be from 1 to 1001.

Note: Make sure that the switch and your network management station are in the same VLAN. Otherwise, you will lose management connectivity to the switch.

The management VLAN is the broadcast domain where management traffic is sent between specific users or devices. It provides broadcast control and security for management traffic that should be limited to a specific group of users (such as the administrators of your network). It also ensures secure, administrative access to all devices in the network at all times.

IP Address

The IP address is a unique identifier for the switch in a network. The IP address is also assigned to the management VLAN. The format is a 32-bit numeric address written as four numbers separated by periods. Each number can be from 0 to 255. The IP address and the default gateway IP address cannot be the same.

Note: When configuring the switch for the first time through Express Setup, 10.0.0.1 and 10.0.0.3 cannot be used as IP addresses.

Make sure that the IP address that you assign to the switch is not being used by another device in your network.

Subnet Mask List

The subnet mask is the network address that identifies the subnetwork (subnet) to which the switch belongs. Subnets are used to segment the devices in a network into smaller groups. The default is 255.255.255.0.

Default Gateway

The IP address for the default gateway. A gateway is a router or a dedicated network device that enables the switch to communicate with devices in other networks or subnetworks. The default gateway IP address should be part of the same subnet as the switch IP address. The switch IP address and the default gateway IP address cannot be the same.

Note: You must specify a default gateway if your network management station and the switch are in different networks or subnetworks. Otherwise, the switch and your network management station will not be able to communicate with each other.

If all of your devices are in the same network and a default gateway is not used, you do not need to enter an IP address in this field.

Switch Password

The password for the switch can be from 1 to 25 alphanumeric characters, can start with a number, is case sensitive, and can have embedded spaces. The password cannot contain a ? or a tab, and cannot have spaces at the beginning or end. The default is cisco.

Note: To complete initial setup, you must change the password from the default password, cisco.

We recommend that you provide a password to the switch to secure access to the device manager.

Confirm Switch Password

Enter the switch password again.

IP Address

The IP address is a unique identifier for the Ethernet management (Fa0) port on the switch. The format is a 32-bit numeric address written as four numbers separated by periods. Each number can be from 0 to 255.

Note: When configuring the switch for the first time through Express Setup, 10.0.0.1 and 10.0.0.3 cannot be used as IP addresses.

Make sure that the IP address that you assign to the Fa0 port is not being used by another device in your network.

Subnet Mask

The subnet mask is the network address that identifies the subnetwork (subnet) to which the Fa0 port belongs. Subnets are used to segment the devices in a network into smaller groups. The default is 255.255.255.0.

Host Name

A name for the switch. The name is limited to 31 alphanumeric characters. The name cannot contain a ?, a space, or a tab. The default is Switch.

System Date

This is the date that the switch automatically read from the network management station or was manually set during initial setup.

System Time

This is the time that the switch automatically read from the network management station or was manually set during initial setup.

Time Zone

This is the time zone that the switch automatically read from the network management station or was manually set during initial setup.

Daylight Saving Time

The check box is automatically enabled only when the selected time zone is in U.S., Europe, or Australia. This check box is not available for all of the other time zones.

Telnet Access

Click Enable if you are going to use Telnet to access the switch CLI. The default is Disable.

Telnet Password

If you enable Telnet access, we recommend that you also set a Telnet password.

The Telnet password can be from 1 to 25 alphanumeric characters, is case sensitive, and can have embedded spaces. The password cannot contain a ? or a tab, and cannot have spaces at the beginning or end.

Confirm Telnet Password

Enter the Telnet password again.

SNMP

Simple Network Management Protocol (SNMP) is a set of protocols for managing complex networks. Enable SNMP if you plan to manage the switch through CiscoWorks or other network management applications.

Click Enable to enable SNMP on the switch. The default is Disable.

SNMP Read Community

The Read community string operates as a password that enables the switch to validate Get (read-only) requests from a network management station. If you set the SNMP read community, users can access MIB objects, but cannot modify them.

The string can be up to 31 characters. The string cannot contain a ?, a space, or a tab. The Read community string cannot be the same as the Write community string.

SNMP Write Community

The Write community string operates as a password that enables the switch to validate Set (read-write) requests from a network management station. If you set the SNMP write community, users can access and modify MIB objects.

The string can be up to 31 characters. The string cannot contain a ?, a space, or a tab. The Write community string cannot be the same as the Read community string.

System Contact

The name of the administrator for the switch or network. The name cannot contain a ? or a tab.

System Location

The physical location of the switch. The location name cannot contain a ? or a tab.
