This is a quick setup guide for suntrunking 1.3
\n– Install the Suntrunking package. Install the most recent suntrunking patch.
\n– grab our ce instance numbers, we can get these from path_to_inst.
\nphoenix# grep ce \/etc\/path_to_inst
\n“\/sbus@3,0\/SUNW, ce@0,8c00000” 0 “ce”
\n“\/sbus@3,0\/SUNW, ce@0,8c10000” 1 “ce”
\n“\/sbus@3,0\/SUNW, ce@0,8c20000” 2 “ce”
\n“\/sbus@3,0\/SUNW, ce@0,8c30000” 3 “ce”
\n– make sure the local-mac-address? setting is set to true
\nphoenix# eeprom local-mac-address?
\nlocal-mac-address?=false
\nphoenix# eeprom local-mac-address?=true
\nIn this case we are going to choose ce0 as the head of the trunk, so we set \/etc\/hostname.ce0 to the hostname and
\nmake sure that
\nit has an entry in our host file.
\nThere are four possible policies:
\n1 – MAC Default policy, at its simplest will divide the traffic equally, ie each interface in this example will handle 25% of
\nthe traffic
\n2 – Round Robin Use each interface in turn
\n3 – IP Destination Address Use IP Destination address to get the transmission path
\n4 – IP Source Address\/IP Destination Address Deterministic connections
\nIn our case we are going to choose round robin as our policy. So to enable this permanently we edit
\n\/etc\/opt\/SUNWconn\/bin\/nettr.sh and add the following line
\nnettr -setup 0 device=ce policy=2 members=0,1,2,3
\nWe now reboot the server
\nphoenix# init 6
\nINIT: New run level: 6
\nThe system is coming down. Please wait.
\nSystem services are now being stopped.
\nPrint services already stopped.
\nSept 3 09:41:12 phoenix syslogd: going down on signal 15
\nThe system is down.
\nsyncing file systems… done
\nProgram terminated

\nConfiguring Sun Trunking devices
\nce trunk members:
\nce0 (head)
\nce1
\nce2
\nce3
\nconfiguring IPv4 interfaces: hme0 ce0.
\nHostname: phoenix
\n…….
\nNow let’s check the configuration
\nphoenix# .\/nettr -conf
\nKey: 0; Policy: 1;
\n60\/433
\nAggr MAC address: 0:14:4f:41:f4:34
\nName Original-Mac-Addr Speed Duplex Link Status
\n—- —————– —– —— —- ——
\nce0 0:14:4f:41:f4:34 1000 full up enb
\nce1 0:14:4f:41:f4:35 1000 full up enb
\nce2 0:14:4f:41:f4:36 1000 full up enb
\nce3 0:14:4f:41:f4:37 1000 full up enb
\nAnd let’s check the load for each interface, this server is restoring data from tape and sending it to other
\nservers, so it has mainly outbound traffic. It is very important to push traffic through the trunk in order to see
\nhow is it really operating.
\nphoenix# .\/nettr -stats 0 interval=5
