Mac Address not displayed in switchport C1000 PoE

[ROZAMX]

Dear all

This time I'm reaching you due to a detail in a CISCO SW C1000 PoE. 17 IP cameras was connected to that SW and the lights are blinking in green and everything seems to be well. The issue is that when I need to know the mac address for each camera attached to the switchport is not displaying anything but in the DHCP server the mac address is related to an IP address.

Details:

CCTV-SW01#show mac address-table int g1/0/18
Mac Address Table
-------------------------------------------

Vlan Mac Address Type Ports
---- ----------- -------- -----

DHCP:

Why is the mac add is appearing in the DHCP but not in the switchports?

Really appreciated,

ROZA.

Hi,

To see the MAC address, make sure the cameras are actually working and active, and then try the "show mac address-table" command again.

Dear Reza,

Well you mean that although the net cables are connected and in green anyway the cameras should be active in order to get the mac add?

Because to get the mac add that I'm doing is by every interface shutdown and no shutdown and after twice attempts I can see the mac add...

Thanks,

ROZA.

Hi,

Yes, make sure the camera is active and working, and you should be able to see the MAC address.
