Peter,

Network visibility wasn't mentioned as a requirement, but it is worth
considering since the ToR switches are the best place monitor server
network I/O, tunneled traffic (VxLAN, GRE etc), storage (iSCSI, FCoE,
HDFS etc).

The Nexus 5548 switch does not include monitoring (i.e. no
NetFlow/sFlow). The Nexus 3048, along with all the other 10G ToR
switches so far mentioned on this thread, supports sFlow and provides
wire speed 10G/40G monitoring.

The following article provides additional background:

Cheers,
Peter

although everyone here seems to hold Cisco in contempt, the Nexux 5548 is a
rock-solid switch - at least that has been my experience with it.

Hello,

I looking some 10G switches, it should work as TOR or core in DC. It
should have more than 40 port 10G in one unit, wirespeed L2 L3, with
virtual routers and some other ip functions like some BGP, OSPF, policy
routing, 1-2U, MLAG, g.8032 (ERPS) trill-like ?

Other important features are  big port buffers ( something similar to
Juniper EX8200 - 512 MB per slot), defined counters accessible via snmp
(like in junos), L3 statistics  accessible via snmp


Extreme 670 looks good but they have small port buffers. It can be also
some small chassis with line cards but the cost per 10G ports is too big..

What vendor, model You prefer or suggest as a solution ?

thanks for help
best,
Peter
