Distributed Time-Based ACLs
Distributed time-based ACLs were alien primarily for the high-end routers. Broadcast time-based ACLs
were advised to be implemented on the VPN-enabled Cisco 7500 alternation routers. As discussed earlier, timebased
ACLs were not initially accurate on the band cards in the Cisco 7500 series. If an interface on a 7500 line
card was configured with a time-based ACL, the packets switched into the interface were not "distributed
switched" through the band card. Instead, they were forwarded to the avenue processor for processing and
therefore did not booty advantage of the broadcast switching capability. The broadcast time-based ACLs
feature allows packets destined for an interface that are configured with time-based ACLs to be "distributedswitched"
through the band card.
Distributed time-based ACLs advantage the achievement allowances of broadcast switching and the flexibility
provided by time-based ACLs. The software alarm charge abide synchronized amid the Avenue Processor (RP)
and the band agenda for the broadcast time-based ACL to action properly.
