Verifying Trap Managers

Use the show running-config command in privileged EXEC modeto verify that the information was

entered.

Configuring IP Information

This section describes how to assign IP information on the Cisco Gigabit EtherSwitch EHWIC. The

following topics are included:

• Assigning IP Information to the Switch, page 69

• Specifying a Domain Name and Configuring the DNS, page 71

Assigning IP Information to the Switch

You can use a BOOTP server to automatically assign IP information to the switch; however, the BOOTP

server must be set up in advance with a database of physical MAC addresses and corresponding IP

addresses, subnet masks, and default gateway addresses. In addition, the switch must be able to access

the BOOTP server through one of its ports. At startup, a switch without an IP address requests the

information from the BOOTP server; the requested information is saved in the switch running the

configuration file. To ensure that the IP information is saved when the switch is restarted, save the

configuration by entering the write memory command in privileged EXEC mode.

You can change the information in these fields. The mask identifies the bits that denote the network

number in the IP address. When you use the mask to subnet a network, the mask is then referred to as a

subnet mask. The broadcast address is reserved for sending messages to all hosts. The CPU sends traffic

to an unknown IP address through the default gateway.

Beginning in privileged EXEC mode, follow these steps to enter the IP information.

SUMMARY STEPS

1. configure terminal

2. interface vlan vlan-id

3. ip address ip-address subnet-mask

4. exit

5. ip default-gateway ip-address

6. end
