Review Questions
Note that more than one correct answer might be valid for multiple-choice questions.
- True or False: CEF-based MLS Catalyst switches use the Layer 3 engine to route the first packet and build flows based in hardware for subsequent packets.
- True or False: The performance of a Catalyst switch using distributed switching is the aggregate of all forwarding engines.
- In CEF-based multilayer switching, which type of adjacency entry is used for features that require special handling or for features that are not yet supported in conjunction with CEF hardware-switching paths?
- Glean adjacency
- Punt adjacency
- Drop adjacency
- Default adjacency
- Which statement describes a TCAM mask associated with the entry access-list 101 deny ip 10.1.0.0 0.0.255.255?
- All 32 bits of source address
- Most significant 8 bits of source address
- Most significant 16 bits of source address
- Most significant 24 bits of source address
- When troubleshooting CEF-based MLS for issues such as being unable to reach a certain IP destination, what two tables need to be verified as a first step in troubleshooting?
- The IP routing table and the IP route-cache table
- The IP routing table and the CEF adjacency table
- The IP CEF FIB table and the adjacency table in TCAM
- The IP routing table and the ARP table
- Which of the following statements is true with regard to CEF-based MLS?
- CEF-based MLS Catalyst switches use the IP CEF FIB and adjacency tables to build FIB and adjacency tables in TCAM for hardware switching.
- CEF-based MLS Catalyst switches use the IP routing and IP ARP tables to build FIB and adjacency tables in TCAM for software switching.
- CEF-based MLS Catalyst switches use the IP CEF FIB and adjacency tables to build MLS flows on-demand in TCAM for hardware switching.
- Describe the steps a multilayer switched packet takes when using CEF-based MLS.
