Problem: How to accurately detect cabling issues?

most cabling issues are non-fatal (initially)

not all wire-pairs may be affected

may not be located at cable termination

specialized test equipment may not be available

Solution: Time Domain Reflectometry

injects a test signal into the cable

measures reflections caused by non-uniform impedance

Detection and (approximate) location

See: http://en.wikipedia.org/wiki/Time-domain_reflectometryOn Copper Ethernet 10/100/1000 ports, (subset of) Catalyst 3k, 4k, and 6k since 12.1(19)EA1

Example: Time Domain Reflectometry (TDR) – 1/2

PSOCRS-3114 13

http://en.wikipedia.org/wiki/Time-domain_reflectometry


But: You may not want to run on all interfaces and only escalate relevant results

Example: Time Domain Reflectometry (TDR) – 2/2

1) Run TDR Test:

switch# test cable-diagnostics tdr interface gigabitethernet1/0/3

TDR test on Gi1/0/9 will affect link state and traffic

TDR test started on interface Gi1/0/3

A TDR test can take a few seconds to run on an interface

Use 'show cable-diagnostics tdr' to read the TDR results.

Note: This will be disruptive!

2) Check Results:

switch# show cable-diagnostics tdr interface gigabitethernet1/0/2

TDR test last run on: December 18 21:05:37

Interface Speed Local pair Pair length Remote pair Pair status

--------- ----- ---------- ------------------ ----------- --------------------

Gi1/0/2 auto Pair A 0 +/- 2 meters N/A Open

Pair B 0 +/- 2 meters N/A Open

Pair C 0 +/- 2 meters N/A Open

Pair D 0 +/- 2 meters N/A Open

Solution: Run on-box from guestshell / Python and parse / filter results before escalating

4)

4. Hundreds of TAC engineers write scripted apps daily (currently >>16’000 apps)

Problem: Most root causes of production outages have been in the network for some time and have been seen before in other networks. How to prevent them from affecting YOUR network?

Solution: Leverage automated Connected TAC Analytics:

1. Customer reports incident (1.3M incidents p.a.)1)

2. Cisco TAC Expert analyses root cause

3. IF analysis can be automated AND there is a preventive action a scripted app is created

3)

Bundling, Versioning, Deprecation and Release Strategy

• API changes within a version will be backward compatible i.e adding a new optional

parameter to existing API URL does not constitute a version change

• Up versioning an API does not guarantee backward compatibility

• When a new version of an API is released, the older version will be

supported for 2 or more years before it is removed

• Telemetry will be used to get insights in API usage and retire unused APIs early in cycle

• Deprecated APIs will respond with appropriate message

(that emphasizes the deprecation, time until it is valid, etc)

Example:

1) In the APIC-EM User Interface,click on [API]

2) Navigate to the desired APIin our example:/network-device/count

Example: Subnets seen by APIC-EM

Problem: How to get a full list of all subnets seen by APIC-EM ?

:

for item in interface_list:

if (item[0] != '') & (item[1] != ''):

subnet = ipcalc.Network(item[0] + "/" + item[1])

subnets.append(...)

:

Solution: Use the APIC-EM REST APIs:

1) For each network device:

2) Extract IP/Subnet Information of all interfaces into a list

3) De-duplicate Subnets

4) Sort the List

Separation of IT areas and buying

Business Owners and App

Developers went straight to Public

Cloud to meet agility and demand.

Security and Data Sovereignty arise.

Focus evolved from Consolidation to

Automation and now it’s all about

Operations become bi-modal – IT

governance AND agile business

SPARK_HEADERS = {'Content-type': 'application/json',

'Authorization': 'Bearer YOUR-ACCESS-TOKEN'}

data=msg,

headers=SPARK_HEADERS)

ChatOps Advanced

Spark Integrations and Bots


Spark API GET vs. Webhooks vs. Bots

1. User’s Clients interact with

the Spark Service

2. Scripts and Apps can GET or

POST messages by calling

the Spark API3. A webhook allows an App to

subscribe for Notifications from

Spark in real time

4. Apps which interact with other

users via Spark can register as

Bots – much like humanoids


Example: ChatOps with Humans Bots

Bot

Human: @Bot Who has the lease for 10.100.252.43?

Bot: 10.100.252.43 is leased by …


Interacting with Humans – ChatOps

Problem: What if your Ops users are road warriors, managers and remote workers?

Solution: ChatOps – Integrate via Cisco Spark REST APIs and/or Tropo.com

Demo at Italtel Booth G12 – Hall 3.2


Example Bot: Exploring and Interacting

Problem: How to explore SDN Controllers and DevOps-style Human Interaction?
