Modes

Interface configuration mode

Usage Guidelines

This command requires autonegotiation to be enabled on the other end of the link.

Although combo ports (ports 1 to 4) on Hybrid Fiber (HF) models support the 1000Base-TX SFP, they cannot be configured to operate at 100 Mbps. The 100-Mbps operating speed is supported only with noncombo ports (ports 5 to 24).

1000Base-TX modules must be configured individually, one interface at a time. 1000Base-TX modules do not support digital optical monitoring. Hotswap is supported for this module when it is configured in 100M mode.

The no form of the command disables 1000Base-TX SFP support.

Examples

The following example configures a 1000Base-TX SFP transceiver to operate at 100 Mbps. 

device(config)# interface ethernet 1/5/1
device(config-if-e1000-1/5/1)# 100-tx
