Q.
Which SFPs are supported on the HWIC-1GE-SFP?
A.
Only SFPs certified by Cisco are supported on the HWIC-1GE-SFP. Table 1 shows a list of all supported Cisco
SFPs. SFPs from other vendors will not be enabled. A syslog message like the following reports that a
nonsupported SFP is inserted.
%HWIC_1GE_SFP-3-VN_DATA_CRC_ERROR: SFP in interface Gi0/2/0 has bad crc
%HWIC_1GE_SFP-6-SFP_IN: Interface GigabitEthernet0/2/0 unknown SFP has been inserted

Q.
Is OIR supported on the SFP module slot?
A.
Yes. OIR is supported on the SFP module slot. When the SFP is inserted and removed when the system is
operational, a syslog message like the following is generated.
%HWIC_1GE_SFP-6-SFP_IN: Interface GigabitEthernet0/2/0 1000BaseT SFP has been inserted
%LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet0/2/0, changed state to
up
%HWIC_1GE_SFP-6-SFP_OUT: Interface GigabitEthernet0/2/0 SFP has been removed
%LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet0/2/0, changed state to
down
