Solaris 10 LACP Trunking w/ Cisco 6509

Today I was tasked with setting up a Solaris trunk to a Cisco switch. The documentation is very lacking, as most only shows one side or the other. Neither show a Solaris 10 machine talking to a Cisco switch, as though this is a very abnormal configuration. For kicks I am putting my configuration here. In this example I am making the switch active LACP and the Solaris box passive LACP.

On the Solaris side, just use good ol ‘dladm’ to create the trunk as specified below, adding more ‘-d INT’ as necessary. On my system the driver was e1000g.

# dladm create-aggr -P L2 -l passive -T short -d e1000g0 -d e1000g1 1

To view the LACP details follow the example below:

# dladm show-aggr -L
key: 1 (0x0001) policy: L2      address: X:XX:XX:XX:XX:XX (auto)
                LACP mode: passive      LACP timer: short
    device    activity timeout aggregatable sync  coll dist defaulted expired
    e1000g0   passive  long    yes          yes   yes  yes  no        no
    e1000g1   passive  long    yes          yes   yes  yes  no        no

To view aggregate statistics follow the example below:

# dladm show-aggr -s
key: 1  ipackets  rbytes      opackets   obytes          %ipkts %opkts
           Total        398054    41821394    278529    28661590
           e1000g0      282639    28945342    1365      171084          71.0    0.5
           e1000g1      23084     2724062     84099     8609560         5.8     30.2

This is what I did to configure the switch. Each port on the switch must be configured the same as GigabitEthernet1/1. Be sure to configure the ports first, before creating ‘interface port-channel 1′

port-channel per-module load-balance
port-channel load-balance dst-mac
!
interface Port-channel1
 switchport
 switchport mode access
 no ip address
!
interface GigabitEthernet1/1
 switchport
 switchport mode access
 no ip address
 lacp port-priority 4096
 lacp rate fast
 channel-group 1 mode active
!

* Update 2/25/2007: Certain versions of the IOS for the Cisco Catalyst 6509 do not suppport Etherchannel trunks faster than 1 Gigabit. This will require an IOS upgrade for the full bandwidth of the LACP trunk to be used.

* Update 4/06/2007: Solaris 10u3 requires reboots after aggregator changes. This is a known bug, without a current fix.
