Figure 1-5 PC without Access to the EnergyWise Network and the Internet
To prevent the PC from accessing the IP network, create and apply an ACL to the ingress interface on
the Layer 2 switch. This ACL permits only traffic sent to an IP address of 255.255.255.255 or 20.0.0.1
and to a UDP port of 43440.
Switch(config)# access-list 102 permit udp any any eq 43440
Switch(config)# access-list 102 permit udp any 20.0.0.1 0.0.0.0 eq 43440
Switch(config)# end
Switch# show access-lists
Extended IP access list 102
10 permit udp any any eq 43440
20 permit udp any 20.0.0.1 0.0.0.0 eq 43440
Note When you are creating an ACL, remember that, by default, the end of the access list contains an implicit
deny statement for all packets if it did not find a match before reaching the end.
CLI Compatibility Issues
EnergyWise Phase 2 is not backward-compatible with EnergyWise Phase 1.
Note Catalyst 6500 switches do not support EnergyWise Phase 1.
To display the EnergyWise version running on your switch, use the show energywise version privileged
