Interface to which ACL 102 is applied

 

 

 

 

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-listsExtended 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 EXEC command.

To display the software version running on your switch, use the show version privileged EXEC command.
