Have you tried set those ports to Auto Negotiation mode?

frankie

No. There is no Q-in-Q and Mikrotik support eta in swOS.

any update on this thread? I'm about to buy a css326-24g switch and for lab use, we need to have q-in-q support. is it there, yet? this thread is a bit old, so I'm hoping the latest switch-os has it (?)

frankie

CSS326 (which uses switch) has Ingress Rate in Forwarding menu, but no Egress Rate. I think switch is capable but good question when it will be available.

frankie

Yes. Disappointing 16MByte Flash in $200 RouterOS device with 512MByte RAM. Such small amount of Flash were in ten year old RB133c rev B. :) Yes I know that CRS326 is a smart switch under control of SwOS or RouterOS system, but for upgrading 10MByte RouterOS file at least so many free MBytes necessa...

frankie

Often after storm ports on Mikrotik devices if not burns out may work in 10mbit full duplex or half duplex mode. Thus check that port status in Winbox/Webfig with PC or another SW/Mikrotik device.

frankie

What do you mean under "not turning on"? Not powering up at all (no led light, no beeper) or you must press a key in console to continue boot process? If so can you please post text output from console boot process?

frankie

Which CPU architecture running RouterOS in CRS326-24G-2S+RM? ARM, MIPSBE or SMIPS? How it compares with CPU performance of CRS125 or CRS226?

frankie

Because it has newer generation switch CPU and faster Management CPU. On CRS326 all SFP+ interfaces can be used in 1G mode if required. CRS226 supports SFP only in port SFP+1.

frankie

Anyone knows on which CPU architecture running RouterOS in CRS326-24G-2S+RM? ARM, MIPSBE or SMIPS? How it compares with CPU performance of CRS125 or CRS226?

frankie

You can use switch2 and SFP port (with S-RJ01 module) on RB3011 for switch 5-pc and NAS.

frankie

If you still need it I made a template for CSS326.

frankie

No. I've updated to 2.1, downgraded to 2.0 and again updated to 2.1 CSS326 without problem from Web GUI (Upgrade menu). Device automatically rebooted with upgraded/downgraded version.

Wire speed without CPU-load.

frankie

This is the limit of 600MHz AR9344 CPU, you can overclock it to 750MHz to get extra 25% power. For gigabit routing better use PowerPC based RB1100AHx2 or Tilera based CCR1009-8G-1S-1S+. Or you can wait for cheaper RB850Gx2 which is also Dual Core PowerPC.

Badcaps?

frankie

Read my post about IC+IP175D. I think same problem with IC+IP178D.

frankie

Same problem on RB2011-UAS-RM and RB435. Try downgrade to ROS 6.0. USB-drivers broken staring from 6.1.

frankie

There are at least two revision of board with different SoC Atheros AR7240-AH1A or Atheros AR7241-AH1A. Locate it and replace with same.

frankie

Write to support@mikrotik.com if you need RB600/800 repair manuals. Bad caps are not always blown. You can measure them with ESR- and Capacitor-meter in-circuit.

Seems normal. When I tested RB2011 without L2TP/PPPoE and without rules in Queue the CPU-load was same at 85Mbit/sec under heavy P2P traffic. You can try overclock CPU to 750MHz to gain additional power.

frankie

System - Routerboard - Settings - CPU Frequency. Max 750MHz available. If you need more RAM buy RB1200 or RB1100AH(x2).

I think USB will be also slow because of software realization of USB stack and will eat CPU. If you need Web Cache use x86 with 2GB RAM and SATA HDD or (m)SATA SSD if necessary.

I've tested with NAT/Masquarade through L2TP tunnel on WAN. 600MHz clocked RB2011 is 30% faster than 680MHz clocked RB450G. 25 rules in firewall, P2P traffic. If RB2011 is overclocked to 750MHz the performance difference is near 40%.

Please read this:

http://routerboard.com/RB951-2n

Says CPU speed is 300MHz.

frankie

Maybe an Atheros AR9344 @ 750MHz would little speed up RB433AH and simplify board design because of integrated 5 10/100 ethernet controller.

frankie

Recently when updated two of RB951-2n the CPU frequency dropped back to 360MHz. Tried downgrade to ROS 5.21 no effect. Only rollback to v5.20 returned 400MHz. Tested on two RB951-2n with Bootloader 2.41 and 3.0. Under v5.20 same boards shows 400MHz.

frankie

Still same problem on RB951-2n as with ROS 5.21, frequency dropped to 360MHz. Tested on two RB951-2n with Bootloader 2.41 and 3.0. Under v5.20 same boards shows 400MHz.

I'll inspect the SOC-s under the heat sinks. Is AR7240 and AR7241 pin compatible or there are two different RB750 layouts for SOCs. Quick search about differences shows only USB 2.0 on AR7241.
