Link Aggregation on Solaris 10

What is Link aggregation:

    Link aggregation is a computing networking term which describes using multiple network ports we can increase the link speed and also increase the fault tolerence and increase teh bandwidth.

Requirement for Link Aggregation:

• You should use dladm command to configure aggregation
• An interface that has been plumb cannot be use for aggregation.
• Interface should of type e1000g0,xge,bge.
• All interface in aggregation should run in same speed and should be full duplex.

To create Link aggregation:

Determine which interface are currently install

# dladm show-link

Determine which interface has been plumb

# ifconfig -a

Create aggregation

# dladm create-aggr  -d e1000g0 -d e1000g1 1

where e1000g0 and e1000g1 are interfaces and 1 is number that identifies aggregation.

Next thing is to plumb the aggreagtion and assign IP

# ifconfig aggr1 plumb 192.xxx.xxx.xxx netamsk 255.255.255.0 up

Check the status of aggregation you just created

# dladm show-aggr

Edit the hostname file

# vi /etc/hostname.aggr1

192.XXX.XXX.XXX

Save and quit.

Reboot the system

# reboot — -r

Verify the aggregation

# ifconfig -a

To remove Interface from aggregation

# dladm show-aggr

# dladm remove-aggr -d e1000g0 1

#dladm show-aggr

To delete aggregation

# dladm show-aggr

# dladm delete-aggr -d 1
