Hello All,
I am experiencing a problem while trying to create port-channel interface. The interface did not come up. If i look at the
show interface port-channel ,
c5548p-3# show interface port-channel 1
port-channel1 is down (BPDUGuard errDisable)
Hardware: Port-Channel, address: 0000.0000.0000 (bia 0000.0000.0000)
MTU 1500 bytes, BW 100000 Kbit, DLY 10 usec
reliability 255/255, txload 1/255, rxload 1/255

Port mode is trunk
auto-duplex, 10 Gb/s
Input flow-control is off, output flow-control is off
Switchport monitor is off
EtherType is 0x8100

Not sure what is causing this error. Could any one please throw some light how to fix this?

Adding few more information
It is a c5548p switch with fimware 5.2(1)N1(1)

without the configuration of the prot hard to say BPDUGuard is enabled when a port is is portfast mode. The port then shuts down when a BPDU is received. What is at the other end of the port-channel?
