Basic Configuration
1
Note: Only one VLAN interface can be assigned an IP address (the default is VLAN 1).
This defines the management VLAN, the only VLAN through which you can gain
management access to the switch. If you assign an IP address to any other VLAN,
the new IP address overrides the original IP address and this becomes the new
management VLAN.
Manual Configuration
You can manually assign an IP address to the switch. You may also need to specify
a default gateway that resides between this device and management stations that
exist on another network segment.
Valid IP addresses consist of four decimal numbers, 0 to 255, separated by periods.
Anything outside this format will not be accepted by the CLI program.
Note: The IP address for this switch is assigned via DHCP by default.
Before you can assign an IP address to the switch, you must obtain the following
information from your network administrator:
• IP address for the switch
• Default gateway for the network
• Network mask for this network
To assign an IP address to the switch, complete the following steps:
1. From the Privileged Exec level global configuration mode prompt, type “interface
vlan 1” to access the interface-configuration mode. Press <Enter>.
2. Type “ip address ip-address netmask,” where “ip-address” is the switch IP
address and “netmask” is the network mask for the network. Press <Enter>.
3. Type “exit” to return to the global configuration mode prompt. Press <Enter>.
4. To set the IP address of the default gateway for the network to which the switch
belongs, type “ip default-gateway gateway,” where “gateway” is the IP address
of the default gateway. Press <Enter>.
Dynamic Configuration
If you select the “bootp” or “dhcp” option, IP will be enabled but will not function until
a BOOTP or DHCP reply has been received. You therefore need to use the “ip dhcp
restart” command to start broadcasting service requests. Requests will be sent
periodically in an effort to obtain IP configuration information. (BOOTP and DHCP
