Troubleshooting Gigabit Ethernet Interface Modules
Step 7 Use the show interfaces GigabitEthernet card/subcard/port command on a different interface to check
the Gigabit Ethernet interface processor type.
Switch# show interfaces gigabitEthernet 10/0/0
GigabitEthernet10/0/0 is up, line protocol is up
Hardware is epif_gigether_port, address is 00d0.5845.1257 (bia 00d0.5845.1257)

Step 8 In this show interface GigabitEthernet card/subcard/port command example, again check the
Hardware field. The hardware is listed as epif_gigether_port, indicating this interface module uses the
Ethernet processor interface type.
Troubleshooting the Gigabit interface module with the Ethernet interface processor is described in the
following sections:
• Eight-Port Gigabit Ethernet Interface Modules, page 10-19
• Two-Port Gigabit Ethernet Interface Modules, page 10-20
• Displaying Gigabit Ethernet Interface Module Configurations, page 10-21.
Troubleshooting the enhanced Gigabit interface module with the Gigabit interface processor is described
in the following troubleshooting sections:
• Troubleshooting Two-Port Enhanced Gigabit Ethernet Interface Modules, page 10-26

Eight-Port Gigabit Ethernet Interface Modules
The eight-port Gigabit Ethernet interface module supports 1000-Mbps Layer 2 or Layer 3 fiber-optic
connections. It provides eight Gigabit Ethernet ports that have Gigabit Interface Converter (GBIC)
modular transceivers and SC-type fiber connectors. The eight-port Gigabit Ethernet interface module is
available with 16K of memory. Routing tables use this memory.
