Split Internet bandwidth with two port

bharat_gole — Tue, 03 Aug 2021 11:11:29 GMT

Hi Team,

we have 100 Mbps ILL Link with 5 usable public IPs which is given by ISP.

now ILL link has terminated in our firewall and we have used it.

now my requirement is, we want to split bandwidth with two port in ICX switch.

ILL link have terminated in Port No 1/1/24

connected our Firewall in Port No 1/1/23 (75 Mbps upload & download)

connected our client Firewall in port No 1/1/22. ( 25 Mbps Upload & Download)

Now i am using the below command and i am facing an issue for upload and download bandwidth.

Please check and if i am wrong then please give me correct command for that.

vlan 90 name ISP_Bandwidth_Split by port
untagged ethe 1/1/22 to 1/1/24
spanning-tree 802-1w
spanning-tree 802-1w priority 0

interface ethernet 1/1/22
port-name L3_FW-PORT13

rate-limit input fixed 25000
rate-limit output shaping 25240
!
interface ethernet 1/1/23
port-name L3_FW-WAN1

rate-limit input fixed 75000
rate-limit output shaping 75240
!
interface ethernet 1/1/24
port-name ISP_L3

Hi Bharat,

Can you please elaborate what issue you are facing?

You only applied for input you also need to apply for output:

rate-limit output

Hope this helps.

Thanks

Hi Bharat,

Pls note that the fixed rate limiting applies to all traffic on the rate limited port. It counts the number of bytes that a port receives in one second intervals. If the number exceeds the maximum number you specified when you configured the rate, the port drops all further inbound packets for the duration of the one-second interval. Unused bandwidth is not carried over from one interval to the next. Once the one-second interval is complete, the port clears the counter and re-enables traffic.

Ruckus recommends that you do not use fixed rate limiting on ports that receive route control traffic or Spanning Tree Protocol (STP) control traffic. If the port drops control packets due to the Fixed rate limiting policy, routing or STP can be disrupted.

Thanks

Jijo

@hashim_bharoocha thanks for reply.

i applied both the limit. see

interface ethernet 1/1/22
rate-limit input fixed 25000
rate-limit output shaping 25000

I am getting download speed 25 Mbps but upload is 11/10 Mbps only.

Hi Bharat,

Could you try with a similar input fixed rate-limiting on the remote side of the link since the issue is with upload only.

Thanks

@jijo_panangat there is no remote side.

ISP link (100 Mpbs ) connected on the port number 1/1/24

and 1/1/23 port for our network (75 Mbps) and 1/1/22 port for other network (25 Mbps).

now i connected my laptop for checking 1/1/22 for speed.
