3 Selecting Data Networking Equipment for a Mitel Connect Deployment Which Data Network Manufacturers Are Supported? What are the Data Network Equipment minimum requirements for a Mitel Connect deployment? Customer Site Cable Plant Requirements Half/Full-Duplex 3

4 Auto (Duplex) Negotiation Configuration NOTE Forced Duplex Configuration NOTE Half Duplex Configuration Summary of Valid Duplex Configurations 4

5 Designing VLANs for VoIP What is a VLAN? TIP The strategic benefits of placing data and voice traffic in separate VLANs include: How to design VLANs into your network? IMPORTANT TIP 5

6 What is a VLAN Tag or VLAN ID? IMPORTANT TIP How is the VLAN Default Gateway created? 6

7 Firewall s are for security, NOT for LAN routing or switching IMPORTANT TIP TIP IMPORTANT TIP 7

8 Summary of Designing Multiple VLANs into the Data Network 8

9 Configuring VLANs for IP Phones Piggy-back the PC to the IP Phone 9

11 Configuring Automatic IP Phone VLAN Assignment LLDP-MED Automatic VLAN Assignment using LLDP-MED during the IP Phone standard boot process is as follows: 400-series IP Phones LLDP OFF LLDP-MED TLV ON with a default of 0 LLDP-MED TLV ON with a non-zero value 11

12 Designing Quality of Service I have enough bandwidth, why do I need QoS? Data Network Design Universal Quality Standards to Support VoIP Latency Jitter Loss Why is the Interface Packet Buffer Memory the real QoS bottleneck and not the link bandwidth? ShoreTel s QoS Traffic Marking Standard Recommendation 12

13 RFCs 2474, 2597 and

14 Mechanisms to generally create and enforce QoS policies include: IMPORTANT TIP The Most Important QoS Design Principles for Mitel 14

15 Configuring Quality of Service Single Site Single Site, Single Voice VLAN Deployment Implicitly or Explicitly Universal LAN QoS/CoS Configuration Steps Cisco MLS-based vs. MQC-based QoS Configuration 15

16 QoS Cisco IOS Interface MLS-based Commands Example 16

17 QoS Cisco IOS Interface MQC-based Commands Example 17

18 Confirm the MQC-based QoS policy or MLS-based Policy-Map is applied to the Voice VLAN interface and monitor 18

19 Configuring Quality of Service Multiple Sites Multi-Site, Multi-Voice VLAN Deployment 19

20 Using Cisco Auto-QoS IMPORTANT TIP In enable mode on the Cisco IOS L2 switch or L3 switch/router, type the following global commands: 20

21 Displaying Auto-QoS Information on most Cisco IOS based switches and/or routers TIP 21

22 22

23 Packet Captures How do I verify the packets are marked with the right DSCP value? 23

24 What About Disaster Recovery? Redundant Services Which services need High Availability? Redundant Links Which connectivity options are possible based on available HA services? Redundant Hardware What hardware is needed for more redundancy and security based on above selections? 24

25 Off-Net Firewall Best Practices Firewall requirements for any relevant Mitel Connect CLOUD configuration includes the following features: Network Address Translation NOTE Mitel Connect CLOUD Destination IP Addresses, DNS and Port Usage Mitel IP Addresses Connect Instance USA UK AU Destination subnet DNS servers Ports 25

26 ShoreTel Sky Legacy Phones Stateful Firewall/NAT Configuration - Connection-Timeout-Adjusting Method Troubleshooting Connectivity NOTE 26

27 In Summary: SCCP Phones: Cisco Pix Firewall SCCP Phone Behind a Cisco PIX Firewall SCCP Phone Behind a Router Configured for NAT 27

28 3 rd Party MPLS DHCP Scope and QoS Best Practice 3 rd Party MPLS DHCP Scope Customer Router Configuration Examples ShoreTel Sky - Cisco DHCP Scope Example ShoreTel Sky - HP DHCP Scope Example Mitel Connect Cloud - Cisco DHCP Scope Example Mitel Connect Cloud - HP DHCP Scope Example NOTE 28
