57 High Availability (HA)

58 Open Cisco IOS XE patchability

59 Software Maintenance Upgrade (SMU) SMU is an emergency point fix positioned for expedited delivery to a customer in case of a network down or revenue-affecting scenario. SMUs are: - Quick (able to deliver point fixes much faster than possible in Cisco IOS ) - Effective (do not require a monolithic code upgrade) - Focused (target the specific area of code that has the issue) SMU is like a medication: - It addresses the issue effectively - In theory, there is no limit to the number you can take - In practice, you want to be selective when using SMUs

60 When will you use SMUs? The Heartbleed Bug Leap Second Security vulnerabilities Cisco vulnerabilities Open source vulnerabilities Critical issues No workaround possible TAC/escalation approved Risks to business Production issues Qualification issues

61 Why are SMUs needed? Software upgrades are challenging Cost Time Scope Expensive upgrades business loss Each device upgrade causes network outage Reduced IT staff slows software rollout Physical presence required New code requires bug analysis, certification SMU Point fixes Reduce validation scope and time

62 SMU types Cold patching (traffic-affecting) - Installation of an SMU will require a system reload in the first release Hot patching (non traffic-affecting) - Hot restart of the patched process can be supported in the future - Installation of an SMU will not require a system reload In-Service Software Upgrades (ISSU) (non traffic-affecting) - Install the SMU using the ISSU mechanism (coming in 16.6) - Will be available only on switches with redundant CPUs

63 GIR Graceful Insertion and Removal

64 Why GIR? To isolate a node with no or minimal impact Hardware replacement Software upgrades Isolating a node today is done manually via CLIs and scripts Layer 3 Layer 2 Shutdown Protocol exchange IS-IS,BGP, OSPF Shutdown Configuration changes

65 Graceful Insertion and Removal Upgrades with no or minimal traffic loss Comprehensive node isolation framework Easy execution with a single command Simple, customizable, non-trafficimpacting Highly customizable workflow
