Manually Assigning Ip Information - Cisco 3845 - Security Bundle Router Software Manual

Chapter 3 Assigning the Switch IP Address and Default Gateway
Note You should only configure and enable the Layer 3 interface. Do not assign an IP address or DHCP-based
autoconfiguration with a saved configuration.

Manually Assigning IP Information

Beginning in privileged EXEC mode, follow these steps to manually assign IP information to a switch
virtual interface (SVI).You can also manually assign IP information to a port if you first put the port into
Layer 3 mode by using the no switchport command.
Command
Step 1
configure terminal
Step 2
interface vlan vlan-id
Step 3 ip address ip-address subnet-mask
Step 4 exit
Step 5 ip default-gateway ip-address
Step 6 end
Step 7 show interfaces vlan vlan-id
Step 8 show ip redirects
Step 9 copy running-config startup-config
To remove the switch IP address, use the no ip address interface configuration command. If you are
removing the address through a Telnet session, your connection to the switch will be lost. To remove the
default gateway address, use the no ip default-gateway global configuration command.
For information on setting the switch system name, protecting access to privileged EXEC commands,
and setting time and calendar services, see
OL-23400-01
Purpose
Enter global configuration mode.
Enter interface configuration mode, and enter the VLAN to which the IP
information is assigned. The range is 1 to 4094; do not enter leading
zeros.
Enter the IP address and subnet mask.
Return to global configuration mode.
Enter the IP address of the next-hop router interface that is directly
connected to the switch where a default gateway is being configured. The
default gateway receives IP packets with unresolved destination IP
addresses from the switch.
Once the default gateway is configured, the switch has connectivity to the
remote networks with which a host needs to communicate.
Note When your switch is configured to route with IP, it does not need
to have a default gateway set.
Return to privileged EXEC mode.
Verify the configured IP address.
Verify the configured default gateway.
(Optional) Save your entries in the configuration file.
