VLAN bandwidth shaping

Thank you for the solution.  Because I only need to guarantee the bandwidth on one vlan, would I need to run the ip access-list map once, and then for each port assigned to vlan 20, run the second command?  

\how would I test that this works?  Would I start a large file transfer on vlan 20 and another on a different vlan?  If vlan 20 stays above 50 MB/s, then I know its working?

ip access-list map_vlan20_to_queue1

permit ip 172.16.2.0 any assign-queue 1 

exit

interface 1/0/1
cos-queue min-bandwidth 0 5 0 0 0 0 0
exit

Hi kbridge,

 

Welcome to our community!

 

I suggest that Class of Service(CoS) function can meet your requirement. 

For the detailed configuration , please refer to the link in Chapter11 CoS Queuing  http://www.downloads.netgear.com/files/GSM7000/Documentation/7000_series_SWA_8.0.3_1Nov10.pdf?cid=wmt_netgear_organic

 

As there is 5 VLANs in your switch, I suggest at first, you need to mapping different VLAN to different Queue(via ACL function), and then set the guarntee bandwidth based on the queue.

 

For example:

step1. mapping VLAN12 traffic to queue 1

ip access-list map_vlan12_to_queue1

permit ip any any assign-queue 1 

exit

 

step2. set the guarntee bandwidth(assume 1G port, 50Mbps should be 5%) based on the queue in the vlan12 members port

interface 1/0/1
cos-queue min-bandwidth 0 5 0 0 0 0 0
exit

 

Hope that it helps !
