We've been running SXH3 on our core switches in our larger 
PoP (6506/SUP720-3BXL + 6509-E/SUP720-3BXL), with 
WS-X6724-SFP + DFC-3CXL line cards.

Suffice it to say, we use them purely for Layer 2 forwarding 
and IS-IS DIS (primary and backup).

The only interesting issue we've faced after moving from 
SXH2a to SXH3 was the switches started requiring our 
fall-back enable password rather than the primary one we 
always used (authentication/accounting is done via 
TACACS+).

Our AAA configuration remained the same, but this issue 
cropped up. We worked around it, as we try to figure out 
what's going on.

Besides that, no other issues to report, but then again they 
really aren't doing anything interesting besides creating 
Layer 2 bandwidth and propagating IS-IS PDU's.

Mark.
