in my previous post I understand that this linecard will be officially released on 18th ... and today I discovered something new in the DS published.
"This extremely comprehensive set of Layer 2 and Layer 3 functions makes this module ideal for data center networks, where density, performance, and continuous system operation are critical."
• 720-mpps Layer 2 and Layer 3 forwarding capacity for both IPv4 and IPv6 packets
The DS is here:
is this new linecard N7K-F248XP-25 a L2/L3 like the M series???
And, according to the Dynamic Configuration Tool it's stated:
"A separate VDC is needed when deploying the N7K-F248XP-25 modules in a chassis that also contains other families of modules (i.e. N7K-M1xxx and N7K-F1xxx).The VDC feature is enabled by the N7K-ADV1K9 license. A separate VDC is NOT required when the chassis contains only N7K-F248XP-25 modules."
And also NX-OS Version 6 required ...
Ciao e grazie!
F2 architecture is also based on SOC (switch on chip). It has a single Fabric ASIC though in comparison to F1 32-port 10g card. It also has all port wire rate with local switching. Also all ports wire rate through Fabric - but only with 2nd generation Fabric modules which Luciano talked in the begining.
It also should have improved L2 latency in comparison even with F1 module.
The F2 module is L2 and L3 capable. It is quite a step up from F1 as it has no L3 capabilites, plus adding FEX to the F2 is a great improvement. As far as F2 vs M1, the M1 still has larger L3 tables and can hold more routes in hardware as well as run OTV. So the two types of modules are for different locations in your data center. M1 is a great fit for your routing edge due to this.
For fabric 2 on 7010 and 7018 you must have NX-OS 6.
As far as the new VDC requirement for F2. Since the Nexus 7000s modules all have their own forwarding engines they must all run in a compatible mode. Think of it like mixing a 6500 with sup2 and a module with a DFC3...you can't do it.
So instead of just saying your chassis can only contain F2 or F1/M1 we are able to seperate the "generations" up by VDCs within the same chassis.
