I have an IE-3000-4TC with an IEM-3000-8SM= expansion module.
The IEM-3000-8SM= has 8 x100Mb SFP ports.
Only SFP port 1-4 recognizes SFP modules:
*Mar 1 23:10:07.524 UTC: %PHY-5-TRANSCEIVERINSERTED: Slot=1 Port=9: Transceiver has been inserted
When I put a SFP module in port 5-8 nothing happens.
SFP module: Cisco GLC-FE-100FX.
IOS version 15.2(4)EA5 IES-LANBASEK9-M
Any suggestions are welcome.
