One thing a router can use is the interface corresponding to the MAC address.
Here's an example. This arp cache shows the connections before I put the computer E520 on the VLAN. nexus7.xyz.net (172.16.1.95) at 08:60:6e:a8:96:0d [ether] on eth2 default (99.230.168.1) at 00:1f:ca:20:46:da [ether] on eth0 linux.xyz.net (172.16.1.10) at 00:15:f2:9c:a7:ac [ether] on eth2 E520.xyz.net (172.16.1.40) at 38:59:f9:e0:7d:5d [ether] on eth2 And after I put it on the VLAN and manually assign the IP address. nexus7.xyz.net (172.16.1.95) at 08:60:6e:a8:96:0d [ether] on eth2 default (99.230.168.1) at 00:1f:ca:20:46:da [ether] on eth0 ? (192.168.5.50) at 38:59:f9:e0:7d:5d [ether] on eth2.5 linux.xyz.net (172.16.1.10) at 00:15:f2:9c:a7:ac [ether] on eth2 E520.xyz.net (172.16.1.40) at <incomplete> on eth2 As you can see, the arp cache shows the computer as now on the VLAN eth2.5 with address 192.168.5.50. Since this is the router computer, that info is available to the DHCP server. The question mark in the host name is due to there not being any DNS entry for that IP address. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
