Additional Information
Figure 4-5 EnergyWise with IP Routing
On Switch 1, to prevent a disjointed domain, manually assign Switch 2 as a static neighbor or the reverse.
Switch(config)# energywise neighbor 192.168.2.2 43440
Switch 1 discovers Switch 3 as a neighbor because they are in the same LAN.
On Switch 1, verify neighbor discovery.
Switch# show energywise neighbors
Capability Codes: R-Router, T-Trans Bridge, B-Source Route Bridge
S-Switch, H-Host, I-IGMP, r-Repeater, P-Phone
Id Neighbor Name Ip:Port Prot Capability

9 Switch-3 192.168.1.3:43440 cdp S I
Switch 1 uses both static and dynamic protocols to detect neighbors.
Verify that switches are in the same domain:
Switch# energywise query name * collect usage

In a routed network, a switch port assigned to a VLAN can be connected to a router interface. The IP
address of the VLAN SVI is 192.168.1.2, and the IP address of the router interface is 192.168.1.1.
Configure the domain:
Switch(config)# energywise domain cisco secret 0 cisco protocol udp port 43440 ip
