Hardware
DDTS # CSCec33248
Pulling the active XCVXL card might result in a traffic outage lasting for greater than 2 seconds. It is
possible to see this approximately 1 out of every 7 active XCVXL card pulls. Excessive traffic outage
from this issue will not occur after a software-induced XCVXL side switch. In this case, you can expect
a traffic hit of less than 60 ms, and traffic will resume normally.
CWDM and DWDM GBIC Compatibility with G1000-4 Cards and G1K-4 Cards
Existing G1000-4 cards are expected to support CWDM and DWDM GBICs, but final qualification
testing was not complete at press time. The online version of the 4.1 user documentation and release
notes will be updated to reflect the final qualification status of CWDM and DWDM GBICs on the
G1000-4 card, when this information is available.
Existing G1K-4 cards do not support CWDM or DWDM GBICs.
