Issue
How to configure Auto Port Aggregation (APA) using Link Aggregation Control Protocol (LACP)?
Solution
Following are the steps for configuring an APA Link Aggregate using LACP:
1. Configure the /etc/rc.config.d/hpietherconf (or applicable NIC file) for all LANs
in an APA aggregate:
HP_IETHER_INTERFACE_NAME[0]=
HP_IETHER_STATION_ADDRESS[0]=
HP_IETHER_SPEED[0]=
HP_IETHER_MTU[0]=
HP_IETHER_FLOW_CONTROL[0]=
HP_IETHER_AUTONEG[0]=
HP_IETHER_SEND_COAL_TICKS[0]=
HP_IETHER_RECV_COAL_TICKS[0]=
HP_IETHER_SEND_MAX_BUFS[0]=
HP_IETHER_RECV_MAX_BUFS[0]=
HP_IETHER_VMTU[0]=
HP_IETHER_ITR_MODE[0]=
HP_IETHER_SEND_CKO[0]=
HP_IETHER_RECV_CKO[0]=
NOTE: If you are running at 1000FD, the defaults should be fine and you may not
have to configure each interface.
2. Configure /etc/rc.config.d/netconf :
a. Assign an IP address to the relevant link aggregate (e.g.,lan900):
INTERFACE_NAME[3]="lan900"
IP_ADDRESS[3]="192.1.1.150"
SUBNET_MASK[3]="255.255.255.0"
BROADCAST_ADDRESS[3]=""
INTERFACE_STATE[3]=""
DHCP_ENABLE[3]=0
INTERFACE_NAME[4]="lan901"
IP_ADDRESS[4]="172.168.1.150"
SUBNET_MASK[4]="255.255.255.0"
BROADCAST_ADDRESS[4]=""
INTERFACE_STATE[4]=""
DHCP_ENABLE[4]=0
b. Assign gateway.
3. Configure /etc/rc.config.d/hp_apaportconf :
(No entries for these interfaces in the netconf file)
HP_APAPORT_INTERFACE_NAME[0]=lan1
HP_APAPORT_KEY[0]=900
HP_APAPORT_CONFIG_MODE[0]=LACP_AUTO

HP_APAPORT_INTERFACE_NAME[1]=lan2
HP_APAPORT_KEY[1]=900
HP_APAPORT_CONFIG_MODE[1]=LACP_AUTO

HP_APAPORT_INTERFACE_NAME[2]=lan3
HP_APAPORT_KEY[2]=901
HP_APAPORT_CONFIG_MODE[2]=LACP_AUTO

HP_APAPORT_INTERFACE_NAME[3]=lan4
HP_APAPORT_KEY[3]=901
HP_APAPORT_CONFIG_MODE[3]=LACP_AUTO
4. Configure /etc/rc.config.d/hp_apaconf :
HP_APA_INTERFACE_NAME[0]=lan900
HP_APA_LOAD_BALANCE_MODE[0]=LB_MAC
HP_APA_KEY[0]=900

HP_APA_INTERFACE_NAME[1]=lan901
HP_APA_LOAD_BALANCE_MODE[1]=LB_MAC
HP_APA_KEY[1]=901
NOTE: This example shows Load Balance mode as LB_MAC. LB_IP or LB_PORT can also be
used.
5. Ensure the switch is properly configured for LACP. (for Cisco 6509, see Appendix E
of HP APA Administrator’s Guide )

7. Restart networking.
