Here are some more notes from my IIUC studies.  As always, corrections requested.

Local Directory

• Allows users to look up names
• Allows names to show up when dialing or receiving a call
• Most phones have a directory button; some have a menu options for the directory

R1(config)#ephone-dn 1
R1(config-ephone-dn)#name Roger Smith

• Directory entries can be added manually

R1(config-telephony)#directory entry 1 1700 Corporate Fax
R1(config-telephony)#directory entry 2 1701 HR Fax

• By default, sorting is done alphabetically by first name.
• Sorting can be changed

R1(config-telephony)#directory last-name-first

More study notes.  Correct if wrong, though I hope I get some of it right since I already since I’m an R&S guy.  :$

**Switchport Configuration
**

• switchport mode access:  This config makes the port an access port that carries the primary and voice VLAN traffic
• switchport mode trunk:  This config akes the port a trunk unconditionally, but it will still send DTP messages
• switchport nonegotiate:  This config keeps the port from sending DTP messages.
• switchport mode dynamic auto:  If the port receives DTP messages, it will become a trunk.  If not, it will be an access port.
• switchport mode dynamic desirable:  The port actively sends DTP messages trying to become a trunk.  This is the default configuration on a Cisco switch.
