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!
