System tracked by MAC address
When a system is tracked by MAC address, Cisco TMS relies on traps from the endpoint containing
the (new) IP address of the system and the MAC address. If the IP address has changed (which
happens when using DHCP), Cisco TMS will update the IP address in the database to the new IP
address. Cisco TMS will then be able to contact the system.
When swapping a system with a new system, the MAC address will change. If Cisco TMS is tracking
the system by the MAC address, the MAC address in Cisco TMS therefore needs to be updated.
This can be done in two ways:
1. Update the MAC address field in the Connection tab for the system with the new system’s MAC
address, click Save/Try, and reboot the system via the remote control or telnet. This will make the
endpoint send a trap to Cisco TMS with its MAC address and IP address, resulting in Cisco TMS
recognizing the MAC address and updating the IP address in Cisco TMS.
2. Set Track system on network by to IP Address and update the IP address to the new IP
address of the system. Click Save/Try to allow Cisco TMS to read the new MAC address, and set
Track system on network by back to MAC Address.
If a Configuration Backup was done of the previous system, a Configuration Restore can now be done
to restore all previous settings and phonebooks.
Note: Verify that the SNMP community name is correct or else this will not work.
