Band Control

[sayrus]

Good night friends,

I wonder how to control bandwidth on an Alcatel model:

System Type: SR-7750 C12
System Version: B-11.0.R4

I found this on google, besides having read too much in manual
$ configure Ethernet 1/5/23 port ingress-rate 10240

however it does not apply direct to the door, it would have to be the logical interface, but does not work.
I saw that has other options for QoS etc, however I did not have success.

I thank everyone.
Thank you!

Hi Sayrus,

I think we need a little more info in order to be able to help.

Are you trying to limit traffic incoming, outgoing or both. Is it an overall port limit you want or per service. Do you need different classes per service etc.

If you try and explain what you are trying to achieve hopefully we can help.

Cheers

Hi
I would limit download and upload
They provide internet for customers, so for example:
The port 1/5/23 is going to switch created client, client2
at the door 1/5/23, put the IP of each client.
So I believe it would be control by service

PS: That and my first contact with Alcatel, had never worked with him such equipment antes.Estou much reading the manual to understand how it works

You can't really achieve per service policing when you set the bandwidth restriction on the port.

The simplest way is to create sap-ingress and sap-egress policies and assign them to the SAP. For example to rate limit ingress to 1meg:

config qos
#create a policy that applies to traffic received on the port
sap-ingress 10 create
#create a queue, queue 1 and 11 (BUM) by default
queue 3 create
#below creates a PIR of 1 meg
rate 1000
exit
#next create a forwarding class
fc af create
#map to a queue
queue 3
exit
#then create your match criteria
ip-criteria
entry 10 create
match
dscp af41
exit
#and put it in the forwarding class
action fc af
#assign the policy ingress to epipe 123 sap 1/1/1:100
conf ser ep 123 sap 1/1/1:100 ingress qos 10

reading it backwards:
If it receive a packet with dscp set to af41 I will put it in the af forwarding class. I have mapped fc af to queue 3 and assigned a peak rate of 1 meg. You can replicate this based on whatever matches you want. Same applies to the sap-egress policy.

QoS is very complicated in SROS. if the above doesnt make sense maybe post your traffic criteria

hi TheCandyManCan

Thanks for attention.
I'm doing right now will soon show the result.

[sayrus]

after several attempts, I not found how to solve this error when I try to create SAP

#config>service>epipe# sap 1/5/22:159 create
MINOR: SVCMGR #1609 Not an access port

You need to change your port from Ethernet mode network to Ethernet mode access or hybrid

It worked ... now he put me in a door warning in use

* A: ClickSMSul> Setup> router> # if port 1/5/22:159
INFO: PIP # 1210 The port is already in use

I'll show you how I did it step by step

First I created as you told me the QoS:

config qos
#create the policy que applies to traffic received on the port
sap-ingress create 10
#create the queue, queue 1 and 11 (BUM) by default
3 create queue
#below creates a PIR of 1 meg
rate in 1000
exit
#next create a forwarding class
fc af create
#Map to the queue
queue 3
exit
#then create your match criteria
ip-criteria
entry 10 create
match
dscp af41
exit
#and put it in the forwarding class
action fc af
#assign the ingress policy to EPIPE 123 sap 1/5/22:159
conf be ep 123 sap 1/5/22:159 ingress QoS 10

Second created the interface:

#configure router interface "band"
address 192.168.1.1/30
no shutdown
1/5/22:159 then the error

With this interface "band" in the port 1/5/22:159 I send internet to the client

Presume your line conf be ep 123 is a typo and its conf ser ep 123?

You cant use the same tag on a router interface and a sap, using the same tag on the same port would confuse the router as to where to send the traffic. If you want an L3VPN you need to use a VPRN, if its an internet service in the global routing table use an IES, if it has to be L2VPN use a routed VPLS.

vprn:
conf ser vprn xxx
int tocust create
add 192.168.1.1/30
sap 1/5/22:159 create
