Hi all,
I curious of what the actual difference is between SPA-2XGE &
SPA-2X1GE-V2.
I'm aware this question has been asked before, but the answer was
just a reference to the product spec sheets which doesn't really
tell me what the difference between the two products are.
What I can tell by reading the spec sheets is that the v2 has SFP
AND RJ45 connectors, while v1 only has SFP.
If I then look at the detailed list of "features and functions" and
compare them I can see that the v2 card lists the following
additional features:
- 802.1ad QinQ termination
- 8000 VLANs per SPA (instead of 4000 in v1)
This is for platforms other than 6k5/7k6 I believe -- even with SIP/
SPA - you cannot do >4095 VLANs/chassis on this platform.
So I ask the question of anyone who knows more on this topic, what
is the real difference between v1 & v2 cards ? I would be putting
them in a SIP-400 in a 7600 chassis.
The v2 card does do QoS (we tested CoS and DSCP marking), we have done
some testing on this in CPOC - it's worth bearing in mind that the SPA
is essentially a framer for the SIP, therefore where there are
features that are not really related to framing, they are likely to be
supported on both SPAs.
I can confirm that the v1 SPA does _NOT_ support QinQ termination - it
will let you configure it with 'encaps dot1q 400 second-dot1q 200',
but will just fail to do anything. I wish that Cisco would fix it so
that these cards that do not support a feature do not let you
configure it!
Kind regards,
Rob
