I'm sure this HAS to be somewhere on Cisco's web site, but a brief general explanation is this: Cisco, and most other vendor's hardware now-adays, has ASIC chips that inspect ingress traffic coming into the switch. It also has a shared memory buffer that it stores cached route-switch

You can install an NM-HSSI and an external E3 CSU/DSU or use an internal NM-1TE3 to terminate a clear channel link. Cisco also built an NM-1A-E3 ATM card as well. In the US the DS3 counterpart to this card was typically used for DSL providers, while the clear channel card or HSSI + external

Steve, There are a few reasons why a lookup through the CEF table is faster than a lookup in the IP routing table. A lookup in the IP routing table is done top down until a match is found, much like how an access-list is processed. The problem, however, is that the IP table is
