FWIW, I've successfully setup a 2x100 Mbps trunk between two D-Link DGE-530T network cards (sk(4)) in an OpenBSD -current (November 2008) box and two cobber ports in a Cisco 2924XL. With regard to the switch, I just added port group X to both interfaces. I don't have access to the OpenBSD box anymore, but I made a hostname.trunkY roughly similar to the following: !ifconfig skZ up !ifconfig skW up !ifconfig trunkY trunkport skZ trunkport skW address netmask netmask Martin

From: http://www.cisco.com/en/US/products/hw/switches/ps607/products_configuration_example09186a0080094789.shtml Note: Catalyst 2900XL/3500XL switches do not support LACP. Catalyst 2950/2955 switches support LACP for channel negotiation with Cisco IOS Software Release 12.1(6)EA2 or later. Cisco IOS Software Release 12.0 supports only static configuration. Catalyst 2940 and 2970 support LACP in all Cisco IOS Software releases. /Pete On 23 Dec 2008, at 08:07, Claudio Jeker wrote: On Tue, Dec 23, 2008 at 12:45:23AM +, Stuart Morgan wrote: Hi Nigel and all, Thanks very much for the suggestion, unfortunately my 3500XL doesn't support LACP - perhaps I need a firmware upgrade? *sw1a#sh ver IOS (tm) C3500XL Software (C3500XL-C3H2S-M), Version 12.0(5)WC16, RELEASE SOFTWARE (fc1) System image file is flash:c3500xl-c3h2s-mz.120-5.WC16.bin The 3500XL are end of life for a good reason.

Etherchannel OpenBSD?
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=8843UP,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=8843UP,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 15:51:09.269539 SSTP STP config root=8000.0:7:eb:93:bb:c7 rootcost=4 bridge=8000.0:d:ed:79:59:86 port=1 ifcost=128 age=1/0 max=20/0 hello=2/0 fwdelay=15/0 pvid=11 15:51:11.260602 SSTP STP config root=8000.0:7:eb:93:bb:c7 rootcost=4 bridge=8000.0:d:ed:79:59:86 port=1 ifcost=128 age=1/0 max=20/0 hello=2/0 fwdelay=15/0 pvid=11 15:51:13.260017 SSTP STP config root=8000.0:7:eb:93:bb:c7 rootcost=4 bridge=8000.0:d:ed:79:59:86 port=1 ifcost=128 age=1/0 max=20/0 hello=2/0 fwdelay=15/0 pvid=11 Any advice would be appreciated!
