Hi, I am playing with my two Dell PowerEdge 1950 and have found something weird.
The two Dell are connected to a Cisco 2900XL switch configured like follows: interface FastEthernet0/24 switchport trunk encapsulation dot1q switchport mode trunk VLAN Name Status ---- -------------------------------- --------- 1 default active 50 VLAN0050 active 51 VLAN0051 active 100 VLAN0100 active 1002 fddi-default active 1003 token-ring-default active 1004 fddinet-default active 1005 trnet-default active On the first Dell with a 4.0 release OpenBSD 4.0 (GENERIC.MP) #936: Sat Sep 16 19:27:28 MDT 2006 bnx0 at pci4 dev 0 function 0 "Broadcom BCM5708" rev 0x12: apic 2 int 16 (irq 5), address 00:15:c5:ef:2a:77 brgphy0 at bnx0 phy 1: BCM5708C 10/100/1000baseT PHY, rev. 6 bnx1 at pci14 dev 0 function 0 "Broadcom BCM5708" rev 0x12: apic 2 int 16 (irq 5), address 00:15:c5:ef:2a:75 brgphy1 at bnx1 phy 1: BCM5708C 10/100/1000baseT PHY, rev. 6 tcpdump shows something like 11:02:12.680092 802.1Q vid 0 pri 0 CARPv2-advertise 36 11:02:12.752324 802.1Q vid 0 pri 0 CARPv2-advertise 36 11:02:12.752390 802.1Q vid 0 pri 0 CARPv2-advertise 36 vlan id is always 0 for every packet.
