There have been many examples of this posted to the various FreeBSD = lists. a quick search via google groups should bring up further examples and discussions. While other cards supposedly work, I only have experience with the fxp (intel) cards. e.g. on the cisco side, interface FastEthernet0/2 description accounting network duplex full speed 100 switchport access vlan 151 no cdp enable interface FastEthernet0/3 description the 192.168.135.0/24 network duplex full speed 100 switchport access vlan 100 no cdp enable interface FastEthernet0/4 description trunk to my FreeBSD box duplex full speed 100 switchport trunk encapsulation dot1q switchport trunk allowed vlan 1,80,81,92,95,98,100,102-160,1000-1005 switchport mode trunk no cdp enable On the FreeBSD side fxp0 is plugged into fa0/4 #10.255.255.254 is an address not used anywhere in our network ifconfig fxp0 10.255.255.254 netmask 255.255.255.255 media 100baseTX mediaopt full-duplex #this will join the vlan/collision domain on port fa0/3 /sbin/ifconfig vlan0 192.168.135.202 netmask 255.255.255.240 vlan 100 vlandev fxp0 mtu 1500 up #if we defined only 1 vlan in the kernel, lets clone/create a new #interface via the create command #join the accounting vlan on fa0/2 ifconfig vlan1 create /sbin/ifconfig vlan1 192.168.199.1 netmask 255.255.255.240 vlan 151 = vlandev fxp0 mtu 1500 up ---Mike On Thu, 28 Nov 2002 22:35:50 -0500, in sentex.lists.freebsd.isp you = wrote: >Jason, >I had a typo, it's a 2924m-xl > >Thanks for the tips however... > >My main problem here is that I don't really know what I'm talking about. >I'm just now looking into configuring vlans with freebsd and literally = know >very little more than about a half hours flip through the man pages. > >I want a freebsd box with 2 fast Ethernet adapters to act as a router, = and >instead of putting several multiport cards into that box, I want one of = the >fast Ethernet adapters to go into a switch, which will have vlans.
