Managing the Switch

Configuring Switch IP Parameters

To manage the switch by way of a Telnet connection or by using an SNMP Network Manager, you must
first configure the switch IP parameters.
Using a BOOTP or DHCP Server
If you are using IP and you have a Bootstrap Protocol (BOOTP) server set up correctly on your network,
you must provide the following information to the BOOTP server:
• Switch Media Access Control (MAC) address, found on the rear label of the switch
• IP address
• Subnet address mask (optional)
After this is done, the IP address and subnet mask for the switch will be downloaded automatically.
You can then start managing the switch using this addressing information without further
configuration. If you use a DHCP server, make sure it is enabled on the required VLAN to receive IP
configuration information.
You can enable BOOTP or DHCP on a per-VLAN basis by using the following commands:
enable bootp vlan [<vlan> | all]
enable dhcp vlan [<vlan_name> | all]
You can disable BOOTP or DHCP on a per-VLAN basis by using the following commands:
disable bootp vlan [<vlan> | all]
disable dhcp vlan [<vlan_name> | all]
To view the current state of the BOOTP or DHCP client, use the following command:
show dhcp-client state
If you configure the switch to use BOOTP, the switch IP address is not retained through a power cycle,
even if the configuration has been saved. To retain the IP address through a power cycle, you must
configure the IP address of the VLAN using the command-line interface or Telnet.
All VLANs within a switch that are configured to use BOOTP to get their IP address use the same MAC
address. Therefore, if you are using BOOTP relay through a router, the BOOTP server relays packets
based on the gateway portion of the BOOTP packet.
NOTE
For more information on DHCP/BOOTP relay, see Chapter 12.
Manually Configuring the IP Settings
If you are using IP without a BOOTP server, you must enter the IP parameters for the switch in order
for the SNMP Network Manager or Telnet software to communicate with the device. To assign IP
parameters to the switch, you must perform the following tasks:
• Log in to the switch with administrator privileges using the console interface.
• Assign an IP address and subnet mask to a VLAN.
