Adding new network int and listening on it.

Hello, I attached new nic to the motherboard, it's even in my ifconfig output, but the switch port is not going up. What should I do on FreeBSD host in order to activate new nic? Here Is the output of ifconfig.
Code: 
bge0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=c019b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4,VLAN_HWTSO,LINKSTATE>
        ether 78:ac:c0:98:00:d4
        media: Ethernet autoselect (100baseTX <full-duplex>)
        status: active
        nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
dc0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=80008<VLAN_MTU,LINKSTATE>
        ether 00:80:ad:3c:3f:0a
        media: Ethernet autoselect
        status: no carrier
        nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384
        options=680003<RXCSUM,TXCSUM,LINKSTATE,RXCSUM_IPV6,TXCSUM_IPV6>
        inet6 ::1 prefixlen 128
        inet6 fe80::1%lo0 prefixlen 64 scopeid 0x3
        inet 127.0.0.1 netmask 0xff000000
        groups: lo
        nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>
where bge0 is my currently used int and dc0 is new one, but maintaining tcpdump -i dc0 gives no output as far as swithport not going up even after no shutdown command on switchport.

Do I need to change the nic?
 
Code: 
status: no carrier
Bad cable? Switch port administratively down?
 
Then the card itself might be dodgy (or the switch port). If there's no carrier it means it doesn't detect a signal, without that carrier the connection simply won't work.
 
ok, looks like it help, but still can't see traffic.
Code: 
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on vr0, link-type EN10MB (Ethernet), capture size 262144 bytes
And there is some movement in dump of interface of switch. But nothing on tcpdump. What it could be?

Is this bad too?
Code: 
vr0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=82808<VLAN_MTU,WOL_UCAST,WOL_MAGIC,LINKSTATE>
        ether 00:13:46:64:3d:ba
        media: Ethernet autoselect
        nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
 
Cards can have two states, physically down (in other words, not connected) or administratively down. The first is the status you see in the ifconfig(8) output, the second is the presence or absence of UP in the flags. A card that's down will not send or receive anything.
 
some cards have crappy auto-negotiation but sometimes they work when you force mediatype and mediaopt (ifconfig)
also older cards don't have auto-x so you need a "flat" cable to connect to a switch or a crossover cable to connect to another computer
