Introduction to the Access Portfolio

Hello, welcome everyone.
My name is Rajat Tayal.
And I’m a Product Manager in AID Campus switching Portfolio Team.
Today, I’ll talk about the Juniper enterprise campus and branch access machine portfolio.
Here is a quick look at the enterprise switching portfolio, which includes the access distribution and core switches.
For access, we’ve EX2300 on the very left, which is an entry level switch, all the way to EX4400 which is a premium access switch offering differentiated hardware and software capabilities.
For distribution, we’ve the EX4600, EX4650, and a QFX5120.
And for core, we’ve the EX9200 which supports modular line cards with 4 slot, 8 slot and 14 slot chassis options.
In this presentation, I’ll be focusing on the campus and branch access switching portfolio.
But before I talk about the individual access switches and their respective positioning, it is also important to highlight some of the key requirements for campus and branch access questions.
If we look at the enterprise campus and branch deployments and what drives changes on the access machine side, wireless access is one of the key catalysts.
Today, enterprises have 802.11AC wave 2, 802.11AX also known as Wi-Fi 6, and earlier generation of wireless access points.
However, almost all vendors including as a general MIST have released Wi-Fi 6E access points and transition to the Wi-Fi 6E technology.
And in future, perhaps Wi-Fi 7 will happen.
Wi-Fi 6E access points are pushing wired connectivity needs to more than one gig because they can support more than one gig of client throughput.
And hence, there is an increasing need for MGig connectivity to the access switches.
The Wi-Fi 6E access points also demand more than 30 Watt of PoE power to be fully operational.
And hence, the need to support 802.3bt.
Both MGig and 802.3bt is a key requirement in campus and branch and will become a must have in the near future.
IoT devices are also exploding in the enterprise.
And these devices are not just limited to cameras, batteries and alarm systems.
We’re seeing requirements for lighting, laptops, and in some cases even access switches to be powered via power or Ethernet.
There are use cases which require uninterrupted power or minimal power interruption during software upgrades, switch reboots, etc.
For these reasons, we’ve introduced capabilities, such as fast and professional theory on our next gen access which is like the EX4100 and the EX4400.
With greater number of devices, higher is the need to segment and secure the network.
Legacy segmentation technologies can be exhaustive, cumbersome, and taxing on the switching resources.
With group based policies, also known as GBP, customers can build granular access control policies with EVPN-VXLAN and GBP and segment their network.
With network security being top of mind and having the ability to monitor attacks in the network is a must have.
With flow based telemetry, we can monitor real time traffic flows against security threats.
In addition to traffic threats, measurement and reporting of packet delays and packet drop reasons can also be determined.
We’re also hearing from our customers the need to encrypt traffic between two switches.
In the past, this would be limited to federal government customers, but a lot more customers are starting to ask for it.
For this reason, we’ve access switches in our portfolio that support MACsec AES256 encryption capability.
Finally, with MIST AI and cloud, we’re on a mission to deliver the best client to cloud experiences to our customers, be Day 0, Day 1 or Day 2.
While the entire access portfolio is cloud ready, the next one EX4100-F, EX4100 and the EX 4400 are cloud native switches.
They’ve a dedicated cloud led to show cloud connectivity states which can be very useful to indicate issues with respect to the cloud connectivity.
Also these switches have significantly lower boot times when compared to legacy 8 switches.
There is wired assurance feature parity as well as Marvis SLE parity across all EX access switches.
Now, let us look at the campus access switching portfolio.
At the entry level, we’ve the EX2300.
Then we’ve the newly introduced EX4100-F followed by the EX3400 and EX4100.
Finally, we’ve the EX4300 and EX4400 which are flag ship MACsec switches.
Let us start with EX2300 which is our entry level family of switches.
