The Gigabit Ethernet Interface Processor (GEIP) is a single-port fixed configuration interface processor that, when combined with the appropriate optical fiber cable, provides one 1000-Mbps Gigabit Ethernet interface that complies with IEEE 802.3z specifications. The Gigabit Ethernet interface operates in full-duplex mode at 1000 Mbps for transmit (TX) and receive (RX) directions.
The GEIP is available on all Cisco 7500 series routers and Cisco 7000 series routers with the 7000 Series Route Switch Processor (RSP7000) and 7000 Series Chassis Interface (RSP7000CI).
The maximum Ethernet frame size is 1518 bytes but GEIP supports MTU size up to 4470 bytes in full-duplex mode for point-to-point links. The mtu interface command (maximum transmission unit) is supported to allow you to specify an MTU size up to 4470 bytes.
