Re: css326 DHCP Snooping

It's now 2021 and DHCP snooping when using VLANs still doesn't work... my DHCP server runs inside a VMWare ESXi virtual machine on a distributed virtual switch (dVS) across most of my VLANs that are set up on the Mikrotiks.If I try to restrict to only the ESXi interfaces where the DHCP server lives,...

Re: GPON SFP+ 3FE46541AA Negotiating Incorrect Link Speed

Secondly, you should think yourself lucky you have anything near 1gbit already.

Some of us are stuck with 80mbit and below (UK FTTC).

FTTP is on the way... but man it seems crazy to be dissatisfied with 1gbit internetz. :)

Re: GPON SFP+ 3FE46541AA Negotiating Incorrect Link Speed

Are you sure the ONT itself supports 2.5gbit Ethernet? There is mention of a fix for 2.5 and 5gbit SFP+ modes for CRS312, but nothing specific about CSS326, so one would assume it supports those already. What's new in v2.13: CRS312: fixed 2.5G & 5G modes; I would check the ONT capabilities with ...

Re: CRS326-24G-2S+ --> CRS328-24P-4S+ ... DAC TX/RX Pauses

Pause frames are due to Flow Control. You can try turning flow control off, but may experience packet loss (retries) instead.

I am also seeing TX pauses between a 2x10gb LAG between Mikrotik switches (DAC SFP+) but it is intermittent. A few is probably normal with FC enabled.

Re: RSTP port cost of LAG group

2 or 2000 for each link depending on path cost mode. I'm using the long mode since I've got some Netgear switches which are hardcoded with the longer format.

See attached image for my 2 x 10GB DAC LAG between Mikrotik switches.

CRS326-24S+2Q+ with 2 x 10GB DAC LACP/LAG to CRS328-24P-4S+

Hi all, I'm fairly new to Mikrotik world but I dived in when I had a need to hook up my new servers (Dell Poweredge's) with 10gbe without spending a fortune on Enterprise kit. I have a CRS328-24P-4S+ which was acting as the core switch, two servers utilising all 4 10GBe SPF+ ports. I have just bough...
