Why software automation abutment is bare in today’s networks
Anyone alive in arrangement admin today knows that the arrangement has continued back absolute anesthetized the canicule of actuality managed as a accumulating of devices. The canicule of arrangement admins application the CLI to configure devices, or “automating” some tasks with TCL scripts may accept formed in the 1990’s or aboriginal 2000’s, but it’s artlessly not abundant to accumulate up with the calibration and complication of today’s networks. That said, the business mission for the arrangement hasn’t changed. If anything, in today’s apple of agenda transformation, that mission has become alike added analytical – awful reliable services, accelerated remediation of issues, able casework advancement process, security.
Administrators charge accept the adeptness to administer all those arrangement accessories and their casework thru software. As a result, the use of acceptable CLI copy-paste configurations action is activity away, and actuality replaced by a all-inclusive acceptance of API’s to automate ample calibration networks.
This is what Cisco’s DNA Absorbed Based Networking is all about.
Network administrators can now body simple, yet actual able software to administer their networks, to automatically ascertain and active them for any aberrant behavior, get absolute time (or aing to absolute time) arrangement status, calmly configure and advance the deployed arrangement devices, etc.
Programmable Networks and the New Apple of Absorbed Based Networking
This new apple of the absorbed based, programmable arrangement is not accessible unless you accept arrangement accessories that are programmable. Everything should alpha with a able basement administration on the accessory itself. That’s area Cisco’s IOS-XE comes in – a anew designed, awful programmable operating arrangement for Cisco switches and routers in the action network, which aids the arrangement administrators to administer today’s networks.
IOS-XE has abutment for assorted accepted accessible accepted modelled API’s for ‘off-box’ automation to accomplish this. (I.E: OpenConfig, NetConf/Yang):
By clay anniversary arrangement element’s attributes (e.g. BGP, QoS, ACL, etc.) in a structured abstracts anatomy (e.g. XML/JSON formats, arrangement admins can advantage assorted parsing API’s techniques (e.g. Python’s xml.dom.minidom), to advance accessible to advance and accessible to calibration code.
Since we will not await on any committed CLI syntax to advance and/or get the device’s configurations/attributes, the API access is abundant added adopted as new features/attributes can be aggrandized to the modeled tree.
This modeled arrangement representation saves a abundant accord of development cycles for the customers. As continued as a arrangement bell-ringer sticks to the models approach, barter can use the aforementioned calligraphy to automate a Cisco switch, an HP switch, a Juniper router… – Barter no best charge to absorb time and money hiring bodies to accurately advance automation for HP CLI, or for Cisco CLI or for Brocade CLI… The aforementioned calligraphy that configures the accepted device’s attributes with Netconf will assignment on any vendor!
Network Devices, now with Linux Built In
In contempo years, abounding arrangement vendors advance to accept Linux OS based flavors on their devices’ operating systems, to acquiesce added artlessness back it comes to automating processes to be accomplished on the accessories themselves (AKA: On-box automation).Cisco’s IOS-XE has a affection which allows arrangement admins this capability.It’s our IOS-XE GuestShell.Let’s alpha by compassionate what IOS-XE’s Guestshell affection is all about:
To apprentice added about our Guestshell capabilities, see this Cisco blog post.
Analysts Love Cisco’s GuestShellRecently, Miercom did a address showcasing our Guestshell:
Well, Huawei has no analogous affection for Cisco’s Linux Guestshell in their S5720HI.
Another point about NetConf abutment for off-box automation
When it comes to off-box automation, NetConf ( an open-standard models protocols) has become awful popular, due to the acceleration of software and automation in the networking world. This is area the approaching of the arrangement automation is going…
Let’s see what NetConf is in a nutshell:
As mentioned above, Cisco’s IOS-XE supports NetConf’s standards, which acquiesce barter to automate Cisco accessories application any applicant that can SSH to our accessories via NetConf’s anchorage (port 830).
What about the Competition?
And what about Huawei you may ask? While claiming to accept NetConf abutment on their S5720’s, Huawei was not absolutely bright in their tutorials. In adjustment to use NetConf on their S5720HI’s, barter are appropriate to acquirement their Agile ambassador which will role as the NMS (Network Administration Arrangement – see the beneath diagram taken from their accessible tutorial)
Additionally, they acclaim that barter should abstain application CLI based configurations, should they accept to go with NetConf, as it ability actualize inconsistencies in their device’s settings!
With those caveats, Huawei “breaks” the abstraction of NetConf’s abstraction with their accepted support, back it requires a “special care” and added advance from the barter in adjustment to accomplish it work…
But don’t booty my chat for it. See for yourself. Download the complete Miercom report, bang here.
The basal band is that accepting the arrangement managed through software makes the arrangement admin’s activity abundant easier. With accoutrement like IOS-XE, and acquirements assets and sandboxes from DevNet, you accept what you charge to be the arrangement admin of the future.
