CBS350 and C9200 routing performance

pj5889
Level 1
Level 1

I'm was looking for inter-vlan routing performance for the two switches.  According to the information on the data sheets the performance for 48 port switches is the same for the CBS350 and C9200. Is that information correct?

"Is that information correct?"

Maybe.  Cisco notes for the CBS350 series:  All switches are wire speed and nonblocking

But unclear whether that's for both L2 and L3 (probably is).

Yet, there's more to switch performance than bps and/or PPS rates.  Egress buffer resource often differ much based on the switch series.  More expensive switches often provide additional features.

Simple example, about importance of egress buffer resources.  Two, or more, gig ports are sending bursts of data to the same gig egress port, or a 10g port is sending bursts of data to a gig port, can such bursts be fully buffered or is some of the traffic dropped?
