CCIE Collaboration Bootcamp is designed to be a challenging five-day course for CCIE Collaboration candidates ready for CCIE Collaboration Lab Exam. This Bootcamp is designed for CCIE Collaboration candidates in the last months or weeks before their CCIE Collaboration Lab Exam. During the week students will tackle challenging full-day mock labs Monday through Thursday. Candidate will practice strategy, time management, learn test taking strategies and expose any weaknesses in order to resolve them before the lab exam. On the final day of the course

VLAN
• VLANs will be required in order to segregate Voice an
Data traffic. In CCIE Collaboration Labs VLAN must be
configured for different type of switches such as 3750 or
EtherSwith Module.
• Port must be trunk and VLAN must be allowed on trunk
port.
• Native VLAM must be configured to be the same as
DATA VLAN

5. 555
VLAN Task
• Configure Voice VLANs for switch ports connecting to IP
Phones at HQ, SiteB and SiteC. Voice VLAN IDs for HQ,
SiteB and SiteC are 10Y, 30Y and 50Y respectively.
• There is a machine connected to each switch port.
Configure switch ports such that machine will be placed
in an appropriate data VLAN. Data VLAN IDs for HQ,
SiteB and SiteC are 20Y, 40Y and 60Y respectively. Refer
to port assignment and VLAN Detail tables for more
information.

Create & Assign VLAN
• To Create VLAN on a SWITCH follow the instruction
below
It is important to name the vlan for
documentation purpose.

Networks Services
• DNS configuration is required if name resolution is required
• Network Time Protocol server must be configured.
• DHCP used to automate network access
• CUCM DHCP or IOS DHCP
DHCP server needs to provide the following:
IP Address and network mask
Default Gateway
Option 150, TFTP server IP address
DNS Server (optional)
Use ip helper-address to forward DHCP request to DHCP Server
Can be locally implemented on IOS router just incase WAN failure occurs.
• CDP is required in order for IP Phone to communicate with AVVID
network

10. 101010
Defining DHCP in CUCM
• Dynamic Host Configuration Protocol (DHCP) server
enables Cisco Unified IP Phones
• You can activate and deactivate DHCP monitor process
by using the Serviceability window of Cisco Unified
Communications Manager. Use the following procedure
to activate the service.
• In Cisco Unified Communications Manager
Administration, use the System > DHCP > DHCP Server
menu path to configure a DHCP server.

16. 161616
Static DHCP Configuration
• You can use DHCP on Cisco Router to reserve particular
IP address for a host. Below is an example of Phone 1
getting the same IP address. Assume Phone 1 MAC
Address is 0200.1000.1234 and client-id 0102.0010.0012.34
Add 01 to the MAC address to get Client ID
ip dhcp pool PH1
host 142.10Y.66.12 255.255.255.0
client-identifier 0102.0010.0012.34
default-router 142.10Y.66.254
option 150 ip 135.Y.100.30
ip dhcp pool PH2
host 142.10Y.66.13 255.255.255.0
client-identifier 0102.0010.0012.35
default-router 142.10Y.66.254
option 150 ip 135.Y.100.30
NOTE: One Pool for Each Phone

17. 171717
DHCP via Database
• A DHCP database contains the mappings between a client IP
address and hardware address, referred to as a binding
• This database contains list of mac address with
corresponded IP address
• static mapping text file must be created with proper file format
• The static bindings must not be deleted when a
DHCPRELEASE is received or must not be timed out by the
DHCP timer.

18. 181818
Configuring the DHCP Server to
Read a Static Mapping Text File
• Configure a single pool
•
• You must disable the DHCP server using
the no service dhcp command before editing the file
• Type service dhcp to enable it and read the text file
• Once done – type show ip dhcp binding to verify
Ip dhcp database static.txt
ip dhcp pool Voice
origin file flash:static.txt

NTP Configurations
To Configure Router to join NTP Server
HQ – Pacific Time Zone GMT -8
r7tor(config)#clock timezone EST -5
r7tor(config)# ntp server 135.11.11.11
SiteB – Eastern Time Zone GMT -5
r7sfo(config)#clock timezone PST -5
r7sfo(config)#ntp server 135.11.11.11
SiteC – GMT +8
r7uk(config)#clock timezone GMT 0
r7sfo(config)#ntp server 135.11.11.11
To Configure Router to act as NTP Server
ntp master  define Router as NTP server
ntp source loopback 0  source NTP Traffic from Loopback interface

Practice Lab Questions
VLAN
Configure Voice VLANs for switch ports connecting to IP Phones at HQ, SiteB and SiteC. Voice VLAN IDs
for HQ, SiteB and SiteC are 10Y, 30Y and 50Y respectively. There is a machine connected to each switch port.
Configure switch ports such that machine will be placed in an appropriate data VLAN. Data VLAN IDs for
HQ, SiteB and SiteC are 20Y, 40Y and 60Y respectively.
DHCP
Configure CUCM Publisher as DHCP server to provide IP Addresses for IP Phones at HQ and SiteB from their
respective Voice subnets. For HQ, use IP address range from 142.10Y.64.20/24 to 142.10Y.64.30/24 For SiteB,
use IP address range from 142.10Y.65.20/24 to 142.10Y.65.30/24 Lastly, configure local Cisco 2801 router as
DHCP server to provide IP addresses for SiteC IP Phones from local Voice subnet. Make sure that the BR
Phone 1 always gets 142.10Y.66.11 and Br Phone 2 should always get 142.10Y.66.12
NTP
Synchronize HQ router with external NTP source at 135.11.11.11. This External NTP server is in UTC time
zone. Configure HQ router in PST time zone which is 8 hours behind UTC. Synchronize CUCM Publisher with
loopback interface of HQ router. SiteB is in CST time zone which is 2 hours ahead of PST. Lastly, SiteC is in
Hong Kong time zone which is 8 hours ahead of Coordinated Universal Timezone. Synchronize SiteC NTP
with external source. Configure CUCM such that IP phones display appropriate time according to the time zone
to which they belong.

• Enable VLAN on trunk port incase if it is not allowed
• Router port if already trunk verify it has all the necessary VLAN
• Ensure VLAN Names are configured
• DHCP must be configured properly.
• Verify all scope settings and file name if needed
• NTP must be configured to ensure server and phone sync their time
