— Deprecates the 3750.

3750, we hardly knew ye.  The 3750 was possibly the coolest switch ever introduced for the data closet and beyond.  It could STACK!   That was pretty cool.  It was a new color.  That was pretty cool.  It could route.  That was pretty cool.
.
The 3850 is an enhancement to the 3750.  It does POE, routes, stacks, all of that.  It also supports flexible netflow and it can be a WLC and support a number of APs inherently.  Like any new switch that deprecates an old one it has higher throughput, bigger buffers, larger TCAMs, etc.
.
I’m curious on the WLC support.  It took me years to build a wirless infrastructure where the AP was its own WLC.  It took me years to consolidate site WLCs(ap integrated) into a single box at each site.  It took me years to consolidate site WLCs to a single box at the data center.  Is Cisco taking a new approach here?  Are we going to forget the tunnels (they suck anyway) and start using WLCs per switch port?  I’m keeping a close eye on things.  I’d love to get rid of those damn tunnels to every single site.

.

I also have an order going out soon for a handful of 3750s.  Is this the time to change to 3850s?  My left says no – give it a few months :: BUGS!  My right says yes, new toys!

Cisco Nexus 6004 and 6001

—Deprecates the 5500 and 5000 series switches if not the 7Ks.

The weight of the 6004 is 120 pounds!  That’s so heavy they specifically call it out on its own section in the data sheet.  Holy Backplane Batman!  It’s a 4U monster.  The 6004 has a large number of 40GbE (48 without add on modules) ports and eventually 100GbE ports.  It can support many more FEX than the 5500.  The 6001 is a 48 port 10GbE switch with 40GbE uplinks.  Let no one say that there is not enough bandwidth in a Corporate Data Center.  Also new to me is the 40Gb Copper Twinax non-breakout cable.  Like any new switch that deprecates an old one it has higher throughput, bigger buffers, larger TCAMs, etc.  I’m looking forward to the new FEXes that will come along with these.
.
I’ll have a buy going out in the next four months or so for some additional 5548s.  This is a dilemma.  Comparison time.

Cisco Nexus B22 FEX for Dell M1000E

Deprecates the 3130

—This may be old news but has just hit my radar.  I was aware of the FEX for my C7000 series chassis but not for my M1000.  I really did not expect these to ever come out.  I’m happy to see them.  These devices are of course switch blades (well FEXes) to install in Dell’s flagship M1000E product.  Prior to these you had to use Dell Force10? integrated switches for 10GbE connectivity to the servers.  Like any new switch that deprecates an old one it has higher throughput, bigger buffers, etc.
.
I’m moving to UCS hardware so this is just something cool for me to know in case we want to upgrade our older M1000E chassis.

  1. The Catalyst 3850 is no doubt the coolest offering from the Cisco switching line of products. It is positioned to be incorporated in the older architecture without making any significant changes. With it, the tunnels will exist between the APs and the controller switch (among others tunnels) and it gives numerous advantages – for eg. multicast without hogging the WLC to AP link (per tunnel) found in older architecture. There are multiple other advantages like per radio/ssid/user QoS policies, enhanced netflow.
