How to configure IPMP in Solaris
This article is about how to configure IPMP in Solaris. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.
IPMP (IPNetwork Multipathing) is one of the main features of Solaris products, its purpose is: first, to increase the throughput of the network, several network interfaces can be easily and quickly bound together, thus playing the role of increasing bandwidth. Second, to achieve the effectiveness of the network interface, through IPMP, you can achieve the redundant use of the network interface, even if a network card is down, other network cards can run effectively, and the service IP on the broken network card will not be lost, so it will be smoothly transferred to other network cards.
Configuration method:
1. Configuration / etc/hosts
#
# Internet host table
#
127.0.0.1 localhost
10.4.128.226 s10 loghost # Primary Interface Address
# Modifications made for IPMP
10.4.128.228 s102 # Second Interface Address
10.4.128.230 s103 # Third Interface Address
10.4.128.225 test1 # Primary Test Address
10.4.128.227 test2 # Second Test Address
10.4.128.232 test3 # Third Test Address
You may wonder why you need so many IP addresses. In fact, it is very simple. Each network card must have an IP address, so three network cards are three IP addresses, so you must give an interface a test address. This address must be a routable address to monitor the status of each interface, error detection and recovery, so that one is 6 addresses.
2. Configure MAC address to avoid conflict
Do you need to modify local-mac-address in eeprom? The value of is true
The specific commands are as follows:
# eeprom local-mac-address?=true
3. Configure the network card address
At this time, you need to configure that hostname.xxx,xxx is your corresponding three Nic device names, and my Nic device names are pcn0, pcn1 and pcn2. Write the contents listed below as in your corresponding file.
# cat / etc/hostname.pcn0
S10 netmask + broadcast + group mpgrp up\
Addif test1 deprecated netmask + broadcast +-failover up
# cat / etc/hostname.pcn1
S102 netmask + broadcast + group mpgrp up\
Addif test2 deprecated netmask + broadcast +-failover up
# cat / etc/hostname.pcn2
S103 netmask + broadcast + group mpgrp up\
Addif test3 deprecated netmask + broadcast +-failover up
4. Restart
# init 6
5. Test margin
Force the network card failover
# if_mpadm-d pcn2
At this point, you will observe that the address on pcn2 and the address on pcn0 are transferred to pcn1.
Re-enable the network card
# if_mpadm-r pcn2
Because I built the environment with a virtual machine, I didn't do any further testing. If you have an experimental environment, you can unplug the network cable to try, or upload a larger file to test the reading and writing speed.
