Cisco 4431 Router licensing

Hello,

 

I have a 1GB connection from my DMZ network to the internet.  It travels from the 1GB cisco switch to the 1GB Cisco 4431 router and then into the internet connection.  I have this on 2 different sites.  One of my sites is ok and i can get download speeds of up to 800mb.  But the other site is only getting around 400mb.

 

My reseller is now saying i only bought a 1GB license for the cisco 4431 and that i should have bought a 2GB license is a synchronous license instead of asynchronous

 

This is what is showing under show run config

 

router#

license udi pid ISR4331/K9 

license boot level appxk9

 

any ideas if he is correct as i have never heard of this before

 

But as i say its working fine at one site and both routers are identical with the same licenses 

 

thanks in advance,Kevin

Re: Cisco 4431 Router licensing

The ISR 4431 has a base thoughput of 500Mb/s.  You'll need to buy a licence to lift that to 1Gb/s.

Re: Cisco 4431 Router licensing

ps.  Use the below command to confirm which performance licence you have installed.

sh platform hardware throughput level

Re: Cisco 4431 Router licensing

Your right

 

sh platform hardware throughput level
The current throughput level is 500000 kb/s

 

looks like i have to think about a new license

 

thanks for your help

It means the total throughput in both directions can not exceed 1Gb/s.  So you could download 800Mb/s and upload 200Mb/s and be ok.  Just the some of the up and downstream can not exceed 1Gb/s at any particular moment in time.

Re: Cisco 4431 Router licensing

Hello, just one more question

 

Here is my output

sh platform hardware throughput level

The current throughput level is 1000000 kb/s

 

But the supplier is saying 

The 1Gb licenses are asynchronous, not 1Gb each way.

 

Does that mean i have 500mb up and 500mb down

What do you think?

Re: Cisco 4431 Router licensing

Excellent answer - that explains what i am seeing in my speed test results

I know i have a line fault at one site because i cannot get over 400mb but at the other site i can range from 600 to 800

 

much appreciated

Kevin
