Hi all,

Does anyone known if trunk(4) supports Cisco Etherchannel?

I have a 3500XL with the following port configuration:

interface FastEthernet0/22
port group 1
switchport trunk encapsulation dot1q
switchport mode trunk
interface FastEthernet0/24
port group 1
switchport trunk encapsulation dot1q
switchport mode trunk
!


Within OpenBSD 4.4 (-stable, generic), I have the following interface config:

trunk0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
       lladdr 00:0c:29:40:2b:dc
       trunk: trunkproto roundrobin
               trunkport vic2 active
               trunkport vic1 master,active
       groups: trunk
       media: Ethernet autoselect
       status: active
       inet6 fe80::20c:29ff:fe40:2bd2%trunk0 prefixlen 64 scopeid 0x9
vlan11: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
       lladdr 00:0c:29:40:2b:dc
       vlan: 11 priority: 0 parent interface: trunk0
       groups: vlan


However running tcpdump on trunk0 does not give the L3 traffic I would expect. The manpage explicitly mentions 802.3ad but other sites on the Internet refer to Etherchannels as being supported (but I don't know if they are confusingly using 'etherchannel', 'port group' and 'LACP' interchangeably)

[r...@gw1-uk]# tcpdump -i vlan11 -vv
tcpdump: listening on vlan11, link-type EN10MB

Any advice would be appreciated!
