IPS port 10Gb

[Wemerson Luiz]

Hello, People!

I have one question:

Why IPS have port 10Gb if he has performance of 4 Gb?

[PAUL GILBERT ARIAS · Accepted solution]

which model you are referring?

On the Data Sheet for the IPS appliances I don't see any 10 Gb Interface:

Hi Luiz,

What is the main issue you are facing ?

How are you measuring the performance ?

Hi, Sid

  My switches core e distribution is Nessus 7010.
 
  IPS 4270 in promiscuous mode don`t work with Nexus 7010.

  I need 10 Giga de throughput between the cor and distribution.
 
  Then I will use three IPS 4270 inline witch between core e distribution.

   Performance:

  On datasheet

  Table 1. Product Specifications
 
  Cisco IPS 4270:
 
  Performance Media-rich = 4 Gbps

  Then why IPS have port 10Gb if he has performance of 4 Gb?

  thanks for your help

I asked someone in Cisco about this topic and the answer I received was that the 10 GE interface is basically to allow connectivity from the IPS to another device with 10 GE interfaces.

I doesn't make sense to me but that was the answer I got.

Hi, Paul!

My switches core e distribution is Nessus 7010.  
   
  IPS 4270 in promiscuous mode don`t work with Nexus 7010. 
 
  I need 10 Giga de throughput between the cor and distribution. 
   
  Then I will use four IPS 4270 inline witch between core and distribution. 
 
Is it corret? 
 
Do you have any document?

No my friend I don't have any documentation. I guess you could contact your preffered Cisco Partner for design assistance.
