IP Commands:
Dell™ PowerEdge™ 1655MC Integrated Switch User's Guide

The IP address for this switch is assigned via Dynamic Host Configuration Protocol (DHCP) by default. This address may be used for management access over your network. If this address is not compatible with your network, you can manually configure a new address You may also need to a establish a default gateway between this device and management stations that exist on another network segment.

ip address

Use this command to set the IP address for this device. Use the no form to restore the default IP address.

Syntax

ip address {ip-address netmask | bootp | dhcp}
no ip address

ip-address - IP address

netmask - Network mask for the associated IP subnet. This mask identifies the host address bits used for routing to specific subnets.

bootp - Obtains IP address from Boot Protocol (BOOTP).

dhcp - Obtains IP address from DHCP.

Default Setting

DHCP

Command Mode

Interface Configuration (VLAN)

Command Usage

You must assign an IP address to this device to gain management access over the network. You can manually configure a specific IP address, or direct the device to obtain an address from a BOOTP or DHCP server. Valid IP addresses consist of four numbers, 0 to 255, separated by periods. Anything outside this format will not be accepted by the configuration program.
If you select the bootp or dhcp option, IP is enabled but will not function until a BOOTP or DHCP reply has been received. Requests will be broadcast periodically by this device in an effort to learn its IP address. (BOOTP and DHCP values can include the IP address, default gateway, and subnet mask).
You can start broadcasting BOOTP or DHCP requests by entering an ip dhcp restart command, or by rebooting the switch.

NOTE: Only one VLAN can be assigned an IP address. When you assign an address to any VLAN, the original IP address is immediately disabled, and the new address takes effect.

Example

In the following example, the device is assigned an address in VLAN 1.

(config)#interface vlan 1
(config-if)#ip address 192.168.1.5 255.255.255.0
(config-if)#

Related Commands

ip dhcp restart

ip dhcp restart

Use this command to submit a BOOTP or DCHP client request.

Default Setting

None

Command Mode

Privileged Exec

Command Usage

DHCP requires the server to reassign the client's last address if available.
If the BOOTP or DHCP server has been moved to a different domain, the network portion of the address provided to the client will be based on this new domain.

Example

In the following example, the device is reassigned the same address.

(config)#interface vlan 1
(config-if)#ip address dhcp
(config-if)#exit
#ip dhcp restart
#show ip interface
IP interface vlan
IP address and netmask: 10.1.0.54 255.255.255.0 on VLAN 1,
and address mode: Dhcp.

ip address

ip default-gateway

Use this command to a establish a static route between this device and management stations that exist on another network segment. Use the no form to remove the static route.

Syntax

ip default-gateway gateway
no ip default-gateway

gateway - IP address of the default gateway.

Default Setting

No static route is established.

Command Mode

Global Configuration

Command Usage

A gateway must be defined if the management station is located in a different IP segment.

Example

The following example defines a default gateway for this device:

(config)#ip default-gateway 10.1.0.254
(config)#

Related Commands

show ip redirects

show ip interface

Use this command to display the settings of an IP interface.

Syntax

show ip interface

Default Setting

All interfaces

Command Mode

Privileged Exec

Command Usage

This switch can only be assigned one IP address. This address is used for managing the switch.

Example

#show ip interface
IP address and netmask: 10.1.0.54 255.255.255.0 on VLAN 1,
and address mode: User specified.
#

Related Commands

show ip redirects

show ip redirects

Use this command to show the default gateway configured for this device.

Default Setting

None

Command Mode

Privileged Exec

Example

#show ip redirects
ip default gateway 10.1.0.254
#

Related Commands

ip default-gateway

ping

Use this command to send Internet Control Message Protocol (ICMP) echo request packets to another node on the network.

Syntax

ping host [count count][size size]

host - IP address of the host.

count - Number of packets to send. (Range: 1-16, default: 5)

size - Number of bytes in a packet. (Range: 32-512)
The actual packet size will be eight bytes larger than the size specified because the switch adds header information.

Default Setting

This command has no default for the host.

Command Mode

Normal Exec, Privileged Exec

Command Usage

Use the ping command to see if another site on the network can be reached.
Following are some results of the ping command:
- Normal response -The normal response occurs in one to ten seconds, depending on network traffic.
- Destination does not respond - If the host does not respond, the switch displays "timeout."
- Destination unreachable - The gateway for this destination indicates that the destination is unreachable.
- Network or host unreachable - The gateway found no corresponding entry in the route table.
Press <Esc> to stop pinging.

Example

#ping 10.1.0.19
Type ESC to abort.
PING to 10.1.0.19, by 5 32-byte payload ICMP packets, timeout is 5 seconds
response time: 0 ms
response time: 10 ms
response time: 10 ms
response time: 10 ms
response time: 10 ms
Ping statistics for 10.1.0.19:
5 packets transmitted, 5 packets received (100%), 0 packets lost (0%)
Approximate round trip times:
Minimum = 0 ms, Maximum = 10 ms, Average = 8 ms
