Right here is my dilemma, I have a Allied Telesis AT-9000/28SP which is a 1Gb switch, I need to connect this to a Cisco Meraki MS425 32 which is a 10Gb switch.

The AT-9000 has 28 SFP ports and 4 copper ports. The MS425 has 32 SFP+ ports and no copper ports. Do SFP+ modules that are backwards compatible to 1Gb speeds exist???

I wonder if you are able to put an SFP into a SFP+ port?

My breif look into this came up pretty inconclusive as far as a guarenteed solution between brands, but plenty of anecdotal "it works" reports of cross brand link and data happening when setting the port manually to 1 gig in the managment.

I think the physical sizes are different.

We run MS-225's at work with 1GB fibre modules.

If you look at the accessories for the MS425 you can buy both copper and 1GB fibre modules for them.

You can put a 1G SFP into a 10Gig SFP+ slot.

The switch has to support it however, but majority do.

Perfect thanks, how do you find the Meraki gear, are you a fan or do you prefer conventional interfaces?

It has it's issues, but it's very simple to deploy if you understand networking concepts. We came from a full juniper stack which I never really got my head around.

We are having Wi-Fi issues with MR32 and MR52's, but it is mostly down to environmental issues.

We have 2 MX100s in a stack with separate internet connections, a soft failover takes 5 minuets. Meaning if the main internet line dies we have to run to the server room and unplug the ethernet connecting the main internet line, or wait 5 minuets for it to figure out the internet has died.

Im only looking at their switches at this stage. I'm running Ruckus for wireless and sonic wall for our security appliance. Failover with the sonicwall is no more than 15 seconds.

Sorry our sonicwalls are 20 seconds for hardware failover and about 15 seconds for WAN fail over.

LOL what is this the 1990s?

SFP+ should take standard SFPs... except stuff less than 1Gbps. SFP+ usually only supports 1Gbps or higher (ie no 10/100).

That is nasty, I'm pretty sure I've seen google occasionally decide that to many pings to 8.8.8.8 is a DoS and drop them. Not sure why they do an entire get when TCP SYN is enough.

300 seconds is a long time for a device to recognise that a link has failed.... In that time my landline and mobile would be ringing non stop. I think I much prefer Sonicwall's fail over options.
