Network High Availability in SOLARIS 11

Network High Availability

1. Trunking
2. DLMP (Dynamic Link Multipathing) only 11.2
3. IPMP (Internet protocol Multipathing)

Trunking + DLMP = Agreegration

Aggregation is at LINK Layer
IPMP is IP Layer/Network Layer.

Aggregation:-

Basically can be done in two modes
         a. Trunking
          b. DLMP

Trunking:-

#dladm create-aggr -l net1 -l net2 aggr0
#ipadm create-ip aggr0
#ipadm create-addr -T static -a 192.168.0.161/24 aggr0/v4

if net1 and net2 has got 1GB speed each would give me 2gb speed but only dependency is that two NIC ports should be connected to the same switch, if switch fails then the Trunking fails, However it works fine if the Switch is configured as cluster in CASCADED MANNER.

However this gives me the availability of NIC until the switch fails..

DLMP:-

#dladm create-aggr -m dlmp -l net1 -l net2 aggr1
#dladm create-ip aggr0
#dladm create-addr -T static -a 192.168.0.162/24 aggr1/v4

if you want to modify the trunking to DLMP

#dladm modify-aggr -m dlmp aggr1

IPMP

Steps
1. Create IPMP Group
2. Put Network ports
3. Assign IP to group

#ipadm create-ip net1
#ipadm create-ip net2
#ipadm create-ipmp -i net1 -i net2 ipmp0
#ipadm create-addr -T static -a 192.168.0.168/24 ipmp0/db1
#ipadm show-addr

by default the health check would be link based.

Monitor the IPMP status and gain INFO

#ipmpstat -i 
#ipmpstat -g 
#ipmpstat -p (to check probe activity)
#ipmpstat -t (to check the targets)

To configure in Probe based.
just assign IP to both the NIC cards

Test is the key word

#ipadm create-addr -T static -a 192.168.0.155/24 net1/test
#ipadm create-addr -T static -a 192.168.0.156/24 net2/test

for deleting the IPMP.

#ipadm delete-addr ipmp0/data1
#ipadm delete-addr net1/test
#ipadm delete-addr net2/test
#ipadm remove-ipmp -i net1 ipmp0
#ipadm remove-ipmp -i net2 ipmp0
#ipadm delete-ip net1
#ipadm delete-ip net2
#ipadm delete-ipmp ipmp0
#ipadm show-addr


Integrated Load Balancer

1. Health check
2. Server group
3. Rule

#pkg install ilb
#svcs ilb
#svcadm enable ilb (will take it to maintenance)
#ipadm set-prop -p forwarding=on ipv4
#svcadm clear ilb
#ilbadm create-hc -h hc-test=PING,hc-timeout=3,hc-count=3,hc-interval=10 hc1
#ilbadm create-sg -s server=192.168.1.101,192.168.1.102 sg1
#ilbadm create-rule -e -p -i vip=192.168.0.200,port=80,protocol=tcp -m lbalg=rr,type=HALF-NAT -h hc-name=hc1 -o servergroup=sg1 rule1
