Good afternoon !
One of our clients is interested and wants to buy Mikrotik CRS and CCR
Our client has a couple of questions, he would be very grateful if you could help us with the answers to them.
1. How many mac addresses does CRS 354-48G-4S+2Q+RM support? For example, if we have ETHERNET 1 as a trunk port, then how many Vlan clients can we connect?

2. How many PPPoE sessions without NAT traffic does CCR1036-8G-2S+ and CCR1072-1G-8S+ support

Thank you!

The capacity of the mac address table and some other parameters of Mikrotik switches can be viewed at https://help.mikrotik.com/docs/display/ROS/CRS3xx+...
For CRS354-48G-4S+2Q+, this value is 32000.

On 1036 8g 2s+ you can keep up to 1000 + nat
Traffic 1.2gb / s
Real example from experience
But if something falls and you fall off at least 50-100 sessions, then it starts to pin wildly, CPU100% minutes 10
Termination of sessions is very strong uses the resource.
However, the uplift is no problem.
After 1000 sessions, the guys get up immediately, without any downloads.
1072 did not try, but I think more than 1000 sessions will pull, but there will be a problem, the same when sessions fall.
1100 - 300 ppoe
4011 - up to 500 ppoe
750 hex gr - 200 ppoe
Cart, if anyone is interested, or can share something vladht

1. How many mac addresses does CRS 354-48G-4S+2Q+RM support?

As for the MAC address table, there is no information, but if a stupid D-Link for 500r can hold a couple of thousand poppies, then I don’t think that such a switch can do less. There tables of poppies should be enough for a whole area, or a small city.

For example, if we have ETHERNET 1 as a trunk port, then how many Vlan clients can we connect?

VLAN-clients - as much as you like, how many VLANs are enough. Who cares? Or you not about VLAN of clients, and about physical ports? How many physical ports after trunk occupation are free, so many clients.
Or clarify your question.

2. How many PPPoE sessions without NAT traffic does CCR1036-8G-2S+ and CCR1072-1G-8S+ support

On the NAG they write that the CCR1036-8G-2S piece of iron holds 5-10k PPPoE sessions, but below they write that in fact about 1k, otherwise the blockage.
In the specification of a piece of iron really there is no such information.

Everything is in the documentation.

Hardware usage: PPPoE server may require additional RAM (uses approx. 9KiB (plus extra 10KiB for packet queue, if data rate limitation is used) for each connection) and CPU power. Maximum of 65535 connections is supported.

The ceiling of sessions for a particular hardware is not difficult to calculate.
Again, the specifications for the 98dx3257 chip have all the data.
