Hi All,
I'm not expertise in the Cisco Switch. We have setup multiple IP Camera at customer site and they use Cisco WS-C2960X-48FPS-L. When the IPC is connected to Cisco PoE Switch, it able to power up but loss connection to the switch. The interface is connected, and it runs on a-Full Duplex and a-10Mb/s speed. But from the switch itself unable to ping this IP Camera. The duplex and speed is set to auto and the switch detect this IP Camera runs on 10Mb/s only. When we try another way, which is forcing the speed to 10Mb/s (execute command "speed 10") then after that IP Camera is connected and the switch able to ping to IPC's IP Address. When we try to change from cisco switch to another vendor switch, once the IP Camera is connected to it, the vendor switch able to detect IP Camera and the speed is 100Mb/s.
My question is, why this is happen?Why cisco 2960X only detect 10Mb/s once the IP Camera connected to it. And we have to set speed 10 to the switchport then after that IP Camera is connected. If we let the speed set to auto, the IP Camera is disconnected. Is anyone able to figure out what is going on. Much appreciated!

Not sure what camera, i have seen this this all depends on vendor equiment. if switch auto negotiate to 10MB, that is agreed both the sides, that is best to set speed 10MB is good option.
have you tried setting up 100MB on cisco switch ? ( on 3rd party switch 100MB full or half duplex ?)

Hi Balaji,
Even set to 100mb/s also wont work. As for the 3rd party switch, it shows 100Mb/s full duplex.

is the same cable ? (used for 3rd party and Cisco switch)
how far switch to Camera (cisco)
how far switch to Camera (3rd party ?)
can you post show run interface x/x and show interface x/x

first do no auto nego
then hardcoded the Speed and duplex.
friend try in one port first.

Do the following:
1. Command: test cable tdr interface <CAMERA PORT>
2. Wait between 5 to 7 seconds for the process to complete.
3. Command: show cable tdr interface <CAMERA PORT>
4. Post the complete output to #3.

I suspect the autonegotiate between both devices is incompatible or takes too long,
some devices use negotiation order low-high, other high-low, which may not always meet mid-way
as result the negotiation results with Cisco in a fallback to 10Mb
you can try to configure autonegotiate enabled but with 100Mb as maximum
speed auto 100
excluding 1Gb in the negotiation may speed up the process enough to succeed
Enter auto to enable the interface to autonegotiate speed with the connected device. If you use the 10 , 100 , or the 1000 keywords with the auto keyword, the port autonegotiates only at the specified speeds.

this is pretty simple .
IP camera does not have an auto-negotiation feature to negotiate with the Switch.
Speed is fixed 10Mbps on the IP Camera port.
Further you can ask Camera vendor if you can change it manually
