Hi all,
We're looking to upgrade some old 3750's and 3750G's whose input queues don't seem to be able to pass 75Mbps without choking: (on a 3750G) Last clearing of "show interface" counters 21w5d Input queue: 1/75/5870052/0 (size/max/drops/flushes); Total output drops: 0). We need the switches to support: - basic QoS policies (mainly, VoIP and routing protocol prioritization) - Flexible NetFlow with NBAR - 125Mbps aggregate throughput via any given interface now, and more in the future. If I had to guess, 450Mbps aggregate within 3 years - OSPF & BGP We don't anticipate stacking these. We're considering: - WS-C3850-24T-E (modular) - WS-C3650-24TD-E (fixed; 2x10G uplinks) - WS-C3650-24TS-E (fixed; 4x1G uplinks) - WS-C3560X-24T-E (modular) I like the idea of the switch being modular, in case we want to put in 10G modules later on, but realistically, can any of these switches even push 1Gbps reliably? After seeing "gigabit" 3750s balk at such low traffic levels, I wonder how much we can really expect any of these switches to push. Of all the options, the WS-C3850-24T-E seems the most flexible and probably most powerful. I was feeling enthusiastic about the 3560X until someone told me that Flexible NetFlow is supported, but only if you buy the 10G module, which costs as much as the switch itself. Do you think we're on the right track? Is the WS-C3850-24T-E probably the best fit? How much traffic have you all seen it push in the real world? Thanks for sharing your experience.
