10. Describe how MLS functions on a switch

MLS 4 step processes

1. The MLS-RP sends MLSP hello packets
2. The MLS-SE identifies candidate packets
3. The MLS-SE identifies enable packets
4. The MLS-SE shortcuts future packets

MLS 3 separate aging times

• Quick aging, utilized to age out partial shortcut entries that never get completed by an enable packet.
• Normal aging, uses for the typical sort of data transfer flow.
• Fast aging, used to age short-term data flows such as DNS, ping, and TFTP.

The Null domain

• Could be done intentionally
• Could be a typing error
• Could have entered the MLS interface command before specifying a VTP domain

When to use MLS

• Need more throughput
• Increased routing performance

A flow mask is used to set the granularity with which MLS creates flows and builds shortcut entries. Its types

• Destination
• Source-destination
• Full
