What is the difference between the SPA-5X1GE and SPA-5X1GE-V2?

[jkeeffe]

Is the V2 just the second generation SPA, or does the V2 fit in one environment, while the non-V2 works in another? Can I use the same SFPs in both versions?

V2 provides the RJ45 interface as well as other goodies. Best to check the data sheet on V2 and compare with previous model:

V2:

Old Model:

One thing to keep in mind is that V2 needs SXI on the 6500, per Release Notes:

http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2SX/release/notes/ol_14271.html

SFPs are compatible on both versions.

HTH,

One thing I noticed when I read the data sheets, is that the non-V2 specifically states under Features and Functions that it supports QoS:

• Ethernet over Multiprotocol Label Switching (EoMPLS)

• QoS

• Hot Standby Router Protocol (HSRP)

• Virtual Router Redundancy Protocol (VRRP)

But the V2 data sheet omits support for QoS, and HSRP/VRRP for that matter.

Do you think that is the case - that V2 really doesn't support QoS, HSRP and VRRP?

I believe it's an omission within that portion of the document.

If you read the beginning of the V2 document, it says:

Cisco I-Flex enhances speed-to-service revenue and provides a rich set of quality of service (QoS) features for premium service delivery while effectively reducing the overall cost of ownership.
