I am experiencing some interface and connectivity problems with a Polycom Camera connected to a 4507R Switch.
Specifically, output errors and collisions.
Here´s the output:
GigabitEthernet2/38 is up, line protocol is up (connected)
Hardware is Gigabit Ethernet Port, address is 0013.7fec.aca5 (bia 0013.7fec.ac

Speed and Duplex are fixed to 10 Mbps - Half duplex.
Probably the transmitted/reveived packets in comparisson to output errors is not too high but I´m experiencing some freeze and slow video problems.
Any idea of what could be happening?
Any comments would be appreciated.
If you hardwire the speed/duplex settings on the endpoint, then you should hardwire the switch end too. Try hardwiring both ends to 100/full.
Thanks for your reply...
The thing is that this camera only connects at this speed and duplex.
Does anyone know why Output Errors are the exact double of collisions???
When a collision occur the packet is retransmitted but shouldn´t be an output error.
Could this be the camera NIC that's not working properly?
