In the
example, a Telnet connection is permitted from the inside network to the outside network on
Monday, Wednesday, and Friday during business hours.
The following con?¬?guration de?¬?nes the time range to implement the ACL and names it:
RouterX(config)#ttiimmee--rraannggee EEVVEERRYYOOTTHHEERRDDAAYY
RouterX(config-time-range)#ppeerriiooddiicc MMoonnddaayy WWeeddnneessddaayy FFrriiddaayy 88::0000 ttoo 1177::0000
Use HTTP to Connect
to Server X
7 p.m.
Access Control List Operation 219
The following con?¬?guration applies the time range to the ACL:
RouterX(config)#aacccceessss--lliisstt 110011 ppeerrmmiitt ttccpp 1100..11..11..00 00..00..00..225555 117722..166..11..00 00..00..00..225555

The following con?¬?guration applies the ACL to the interface:
RouterX(config)#iinntteerrffaaccee EEtthheerrnneett00//00
RouterX(config-if)#iipp aaddddrreessss 1100..11..11..11 225555..225555..225555..00
RouterX(config-if)#iipp aacccceessss--ggrroouupp 110011 iinn
The time range relies on the router system clock. The router clock can be used, but the feature
works best with Network Time Protocol (NTP) synchronization.
