This procedure details how to configure the boot interface for reliable communications with your network
server. Make sure you are at the Exec mode prompt.
Step 1
Enter the Global Configuration mode by entering the following command:
[local]host_name# configure
The following prompt appears:
[local]host_name(config)#
Step 2
Enter the following command:
[local]host_name(config)#boot interface { local-eth1 | local-eth2 } medium { auto | speed { 10 | 100 | 1000 } duplex
{ full | half } } media { rj45 | sfp }
For complete information about the above command, see the Global Configuration Mode Commands chapter in the
Command Line Interface Reference.
Use port 1 for network booting.
If the speed is manually configured, you must also configure the duplex mode. In addition, you must ensure that the
network server configuration supports the speed and duplex configuration.
Network speed for MIO/UMIO/MIO2 is fixed at 1000.
Ethernet networking rules dictate that if a device's interface is configured for auto-negotiation is communicating with a
device that is manually configured to support full duplex, the first device will negotiate to the manually configured speed
of the second device, but will only communicate in half duplex mode.
The media for MIO/UMIO/MIO2 port 1 is fixed at rj45.
Step 3
Save the configuration as described in the Verifying and Saving Your Configuration chapter.
Configuring the Boot Network
Boot network parameters define the protocols and IP address information for MIO/UMIO/MIO2 interfaces
used to reach the external network server that hosts the operating system software image file. To configure
boot network parameters, make sure you are at the Exec mode prompt.
Step 1
Enter the Global Configuration mode by entering the following command:
[local]host_name(config)#configure
The following prompt appears:
[local]host_name(config)#
Step 2
Enter the following command:
[local]host_name(config)# boot networkconfig { dhcp | { { dhcp-static-fallback | static } ip address mio5
ip_address5 [ mio6 ip_address6 ] netmask subnet_mask [ gateway gw_ip_address ] } }
For complete information about the above command, see the Global Configuration Mode Commands chapter in the
Command Line Interface Reference.
The following command configures the boot network to communicate using DHCP, with a static-fallback IP address for
MIO/UMIO/MIO2 in slot 5 of 192.168.206.101 and a Class C netmask.
[local]host_name(config)# boot networkconfig dhcp-static-fallback ip address mio5 192.168.206.101 netmask
255.255.255.0
