Post by: itech on January 11, 2018, 01:47:24 AM
hi everyone
i have a server host on cisco switch.its interfaces configured as LACP.when i use "sh cdp" command i see  interfaces of server, its contain numeric device id for example 00155d1e9822
Do you have any idea about this issue?

i've seen stuff like this when I do a 'show cdp neigh' and Cisco phones are connected.
probably just a device ID.

That's a Microsoft MAC address, so the MAC given for the LACP is likely software-configured to override the physical MAC addresses on the server.

yes this is mac address of physical server but when i look at the details ,this server's ip address seems to belong to the virtual server

... which is using the virtual switch to reach the network, so it will use the MAC address of the server when it connects to the physical network.
