(historical) Cisco Design Lifecycle |
Prepare, Plan, Design, Implement, Operate, Optimize (PPDIOO) |
|
|
PPDIOO - Prepare |
Establishes organization and business requirements, develops a network strategy, and proposes a high-level architecture |
|
|
PPDIOO - Plan |
Identifies the network requirements by characterizing and assessing the network as well as performing a gap analysis |
|
|
PPDIOO - Design |
Provides high availability, reliability, security, scalability, and performance |
|
|
PPDIOO - Implement |
Installation and configuration of new equipment |
|
|
PPDIOO - Operate |
Day-to-day network operations |
|
|
PPDIOO - Optimize |
Proactive network management and modifications to the design |
|
|
What document from the Design Phase is constantly updated? |
Project plan |
|
|
3-layers of hierarchical network design? |
Core, Distribution, Access |
|
|
Core layer characteristics? |
Fast transport, high reliability, redundancy, fault tolerance L3 switches, equal-cost paths |
|
|
Distribution layer characteristics? |
Policy implementation, VLAN routing, broadcast and multicast domain definition, demarcation between static and dynamic routing protocols L3 links to core, FHRP protocols |
|
|
Access layer characteristics? |
Layer 2 switching, port security, STP, NAC, PoE, QoS tagging L2 switches, potential L3 to distribution |
|
|
Switch domains? |
|
|
|
Router domains? |
|
|
|
PortFast |
Bypass straight to forwarding |
|
|
UplinkFast |
Enables fast uplink failover on an access switch |
|
|
BackboneFast |
Enables fast convergence in distribution and core lapers |
|
|
Loop Guard |
Prevent an alternate or root port from being the DP is BPDUs are lost |
|
|
Root Guard |
Prevents external switches from becoming root |
|
|
BPDU Guard |
Disable PortFast if BPDU is seen |
|
|
BPDU Filter |
Suppresses BPDU on ports |
|
|
CGMP |
Cisco Group Management Protocol - Controls multicast at L2. Routers communicate to L2 switches about multicast hosts |
|
|
IGMP Snooping |
Switches listen to IGMP messages, if a host sends a query to the router, the switch adds the host to the multicast group and permits that port to receive multicast traffic |
|
|
When do you prototype? |
After design and before implement |
