dhcpinfo command

This command displays the IP configuration that is assigned by a DHCP server to the primary management module external network interface, blade server management network interfaces, and I/O module DHCPv6 server.

Note: The dhcpinfo command does not apply to management module channel eth1, which always uses a static IP configuration.

Table 1. dhcpinfo command
Function	What it does	Command	Valid targets
Display Ethernet channel 0 DHCP configuration for management module	If the IP configuration for management module eth0 is assigned by a DHCP server, the configuration that is assigned by the DHCP server and DHCP server information is displayed. If the IP configuration for eth0 is not assigned by a DHCP server, an error message is displayed. Possible configuration values returned are: -server dhcp_ip_address -n hostname -i ip_address -g gateway_address -s subnet_mask -d domainname -dns1 primary_dns_ip_address -dns2 secondary_dns_ip_address -dns3 tertiary_dns_ip_1address -server6 IPv6_dhcp_ip_address -i6 IPv6_address -d6 IPv6_domainname -dns61 IPv6_primary_dns_ip_address -dns62 IPv6_secondary_dns_ip_address -dns63 IPv6_tertiary_dns_ip_1address	`dhcpinfo -eth0`	`-T system:mm[x]` where x is the primary management-module bay number.
Display Ethernet channel 0 DHCP configuration for standby management module	If the IP configuration for the standby management module eth0 is assigned by a DHCP server, the configuration that is assigned by the DHCP server and DHCP server information is displayed. If the IP configuration for eth0 is not assigned by a DHCP server, an error message is displayed. Possible configuration values returned are: -server dhcp_ip_address -n hostname -i ip_address -g gateway_address -s subnet_mask -d domainname -dns1 primary_dns_ip_address -dns2 secondary_dns_ip_address -dns3 tertiary_dns_ip_1address -server6 IPv6_dhcp_ip_address -i6 IPv6_address -d6 IPv6_domainname -dns61 IPv6_primary_dns_ip_address -dns62 IPv6_secondary_dns_ip_address -dns63 IPv6_tertiary_dns_ip_1address	`dhcpinfo -eth0 -standby`	`-T system:mm[x]` where x is the primary management-module bay number.
Display management network DHCP configuration for blade server	If the IPv6 configuration for the specified blade server management network Ethernet channel is assigned by a DHCP server, the IPv6 IP address is displayed. If the IP configuration for the specified blade server management network Ethernet channel is not assigned by a DHCP server, an error message is displayed.	`dhcpinfo -eth` x where x is the blade server management network channel number to display.	`-T system:blade[x]` where x is the blade server bay number.
Display DHCP configuration for I/O module	If the IPv6 configuration for the specified I/O module is assigned by a DHCP server, the IPv6 IP address is displayed. If the IPv6 configuration for the I/O module is not assigned by a DHCP server, an error message is displayed.	`dhcpinfo`	`-T system:switch[x]` where x is the I/O-module bay number.

Example: To display the DHCP server assigned network settings that do not support IPv6 for Ethernet channel 0, while management module 1 is set as the persistent command environment, at the system:mm[1]> prompt, type

                  dhcpinfo -eth0

The following example shows the information that is returned:

               system:mm[1]> dhcpinfo -eth0
-server 192.168.70.29
-n MM00096BCA0C80
-i 192.168.70.183
-g 192.168.70.29
-s 255.255.255.0
-d linux-sp.raleigh.ibm.com
-dns1 192.168.70.29
-dns2 0.0.0.0
-dns3 0.0.0.0
system:mm[1]>

To display the DHCP server assigned network settings that support IPv6 for Ethernet channel 0, while management module 1 is set as the persistent command environment, at the system:mm[1]> prompt, type

                  dhcpinfo -eth0

The following example shows the information that is returned:

               system:mm[1]> dhcpinfo -eth0
