If you know Linux, you will love EOS, as it gives you the POWER that NO other network device operating system has before

Arista7124SX#bash
Arista Networks EOS shell
[admin@tm225 ~]$
Arista EOS also provides
the user complete access to the
Linux kernel of the switch.
To enter it, simply enter bash:
No other switches have this
capability
tm225#bash sudo tcpdump I e1
tcpdump: WARNING: fabric: no IPv4
address assigned
tcpdump: verbose output suppressed, use
-v or -vv for full protocol decode
listening on fabric, link-type EN10MB

'hello', helpdesc='Says hello' )

5 BasicCli.UnprivMode.addCommand( (
tokenHello, doHello ) )
localhost>show hello ?

Hello World.

You can create and add new commands by
simply writing your own python script:
You can easily do a tcpdump on an Arista
switch with no impact to the CPU. You can
see ospf hello packets being received](https://image.slidesharecdn.com/2ndsdninterestgroup-session3121218-140611204505-phpapp01/85/2nd-SDN-Interest-Group-Seminar-Session3-121218-29-320.jpg)

- 32. Brocade Hybrid Need: Deliver value-added services for specific customer traffic on top of standard forwarding Solution: OpenFlow as an overlay on top of a unprotected IP WAN network Unprotected Hybrid port mode: - Hybrid port mode means: WAN ports run OpenFlow concurrently with traditional MPLS/IP routing - Unprotected means: OpenFlow is allowed to affect MPLS/IP traffic - Protected means : WAN ports run OpenFlow concurrently with traditional MPLS/IP routing Protected mode ensure OpenFlow cannot affect MPLS/IP routed traffic Value-added Services with OpenFlow on top of Production Network
