To prevent system problems, do not use Gigabit Interface Converters (GBICs) from third-party vendors.
Caution
Use only the GBIC that shipped with your Ethernet line card. The GBIC might contain an internal
EPROM that identifies it to the Cisco IOS software.
Only use small form-factor pluggable modules (SFPs) supplied by Cisco in Cisco XR 12000 Series
Caution
Routers. Each SFP module contains an internal serial number that is security programmed by the SFP
module manufacturer with information that provides a way for Cisco (through the Cisco IOS software)
to identify and validate the SFP module as a module type that is qualified by Cisco to operate with
Gigabit Ethernet line cards. Unapproved SFP modules (those not purchased directly from Cisco) do not
work.
4-Port Gigabit Ethernet ISE Line Card
The 4-Port Gigabit Ethernet ISE line card provides Cisco XR 12000 Series Routers with four optical
Gigabit Ethernet interfaces on a single line card, using field replaceable SFP modules. The line card
provides high-speed connections to other network devices, such as another Cisco XR 12000 Series
Router, other routers, or layer-2 and layer-3 switches that support Gigabit Ethernet interfaces. The 4-Port
Gigabit Ethernet line card throughput is limited to 4 million packets per second (4 Mpps) at 64 bytes, so
all four ports cannot run at line rate.
