Hi,
Can you tell me shortly, If in Ros 7.15 on ccr2116, it is possible to have per ip down/up shaper in hardware?
for example
1000 subscribers on 10mb/s down/up
800 subscribers on 20mb/s
2000 subscribers on 30mb/s?
Hi, the short answer is - yes, it is possible. But I guess there will be a follow-up question "how?" - that I'll answer a bit later.
Starting from v7.15, RouterOS allows setting per-queue shaper. One option to assign traffic to a queue is by setting a QoS Profile via a Switch Rule.
For simplicity, let's imagine that all clients are connected to sfp-sfpplus1, forwarding all traffic to sfp-sfpplus2. Feel free to expand the example based on your needs.
- Create QoS profiles. We can leave the default profile for 10M subscribers, but redirect 20M and 30M subscribers to queue2 and queue3, respectively.Code:
/interface/ethernet/switch/qos/profileadd comment="20M subs" name=tc2 traffic-class=2add comment="30M subs" name=tc3 traffic-class=3 - I guess we don't want 30M traffic to completely block 20M and 10M subscribers, so let's schedule all three traffic classes under the same priority group, adjusting the weight based on speed:Code:
/interface/ethernet/switch/qos/tx-manager/queueset [find where traffic-class=1] schedule=low-priority-group weight=1set [find where traffic-class=2] schedule=low-priority-group weight=2set [find where traffic-class=3] schedule=low-priority-group weight=3 - Limit egress rate of the respective queues:Code:
/interface/ethernet/switch/qos/portset sfp-sfpplus1,sfp-sfpplus2 egress-rate-queue1=10Mset sfp-sfpplus1,sfp-sfpplus2 egress-rate-queue2=20Mset sfp-sfpplus1,sfp-sfpplus2 egress-rate-queue3=30M - Define ACL rules to match traffic by IP. For example, if all 20M subs are in 192.168.24.0/21subnet, and 30M - 192.168.32.0/21:Code:
/interface/ethernet/switch/ruleadd new-qos-profile=tc2 ports=sfp-sfpplus1 src-address=192.168.24.0/21 switch=switch1add new-qos-profile=tc2 ports=sfp-sfpplus2 dst-address=192.168.24.0/21 switch=switch1add new-qos-profile=tc3 ports=sfp-sfpplus1 src-address=192.168.32.0/21 switch=switch1add new-qos-profile=tc3 ports=sfp-sfpplus2 dst-address=192.168.32.0/21 switch=switch1
Here is the print output for reference:

We'll add "/in/eth/sw/qos/port print rates" for more convenient output in RouterOS v7.16.
