Hi,

I'm trying to find out what the real differences are between the 2800-series and new 2810-series switches are. I have studied the specifications, and as far as I can see, 2810 does not support routing, but apart from that they appear almost identical. Is this a correct analysis?
The 2800-series had some performance problems that could be circumvented with the "qos-passthrough"-fix. Has this problem been eliminated in the new switches? The prices don't differ much, so what should one go for?

Perhaps I should clarify the question above. Which series of switches is better, if we assume that I don't need routing, and that the prices are identical (which they almost are, at least in Sweden).

There is a slight physical difference on switch.
2824/48: 14.4 x 17.32 x 1.75 in.
(36.58 x 43.99 x 4.45 cm)
2810: 12.7 x 17.4 x 1.7 in.
(32.26 x 44.2 x 4.32 cm)
Solve rack mount size problems
and you are right no routing.

From what I can see the main differences are:

Size:
2810 smaller by a minimum 4cm depth for better rack fit.

Routing:
2810 is Layer 2 only, no static routes.

Processor:
2800 is Motorola PowerPC MPC8245, 266 MHz
2810 is MIPS BCM5836, 264 MHz

Throughput:
2800 is 34.65/69.3 million pps
2810 is 35.7/71.4 million pps

So 2810 slightly higher throughput.

Weight:
2810 is about 3lb lighter than 2800.

Temperature:
2810 max temp is around 18degreesF lower than 2800, so cooler rooms and possibly quieter switch/fans in 2810.

Altitude:
2800 is 15091ft
2810 is 10000ft

So if 5091ft more is needed, you're out of luck with the 2810 :)

Overall similar products, but routing/size/weight/temp differences can be important to some customers.

Yes, but these are really minor points. I mean, why go through all the trouble with releasing a new model with just 3% increased output, and slightly different physical size..?
Perhaps the 2800-series will be phased out?

The 2810 does not do data-driven IGMP like the 2800 series does. (Only IGMP Snooping). It's not that important for most people... if you are using IGMP though I would pick a data-driven switch given the choice.

The 2810 is also quieter than the 2800's.
