Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I am running OpenIndiana (oi_151a8) and have two NICs aggregated using LACP connected to a Cisco WS-C3560G-48TS. Both the server and the switch show the aggregate link as up. But while link layer traffic is visible ('snoop' shows ARP requests etc), I can not pass any IP traffic (ping, ssh all fail). The really strange thing is that the aggregate link can obtain a DHCP address, which provides the correct gateway, name servers etc. My initial thoughts were that there was a problem with the VLAN configuration, but the switch is running everything on VLAN1. I also tried explicitly adding this on both ends, but without success (OI won't let me configure a VLAN with the native VLAN). Any ideas?

I think I need to start again from scratch: upon reboot I noticed a collection of errors along the lines of: svc:/network/physical:default: Method “/lib/svc/method/net-physical” failed with exit status 96. network/physical:default misconfigured: transitioned to maintenance (see ‘svcs -xv’ for details) –  user189271 Sep 20 '13 at 2:58
