RE: Port Channel not coming up

The logical interface is already up.
I was expecting a 2Gig interface and both g1/5 & g4/15 as members of the
channel.
Still unable to bring up g4/15.

rp01#sh int po3
Port-channel3 is up, line protocol is up (connected)
  Hardware is EtherChannel, address is 00d0.c0d6.4fd2 (bia
00d0.c0d6.4fd2)
  MTU 1500 bytes, BW 1000000 Kbit, DLY 10 usec,
     reliability 255/255, txload 1/255, rxload 1/255
  Encapsulation ARPA, loopback not set
  Keepalive set (10 sec)
  Full-duplex, 1000Mb/s
  input flow-control is off, output flow-control is off
  Members in this channel: Gi1/5
  ARP type: ARPA, ARP Timeout 04:00:00

Allow the native VLAN on the trunks of the physical and logical
interfaces.

        Hello,

        Any suggestion as far as bringing this port channel up?
        The port channel interface is up but the other member of the
channel is
        down and doesn't show as a member of that channel.
