Flow Control — Allows automatic or manual selection of support for flow control and indicates the type of flow control currently in use.
l
Autonegotiation/Port Capabilities — Allows autonegotiation to be enabled/disabled and indicates the capabilities of the port that are advertised during
l
autonegotiation:
10h — Supports 10-megabits per second (Mbps) half duplex.
¡
10f — Supports 10-Mbps full duplex.
¡
100h — Supports 100-Mbps half duplex.
¡
100f — Supports 100-Mbps full duplex.
¡
1000h — Supports 1000-Mbps half duplex.
¡
1000f — Supports 1000-Mbps full duplex.
¡
Sym — Supports symmetric operation of full-duplex flow control. The port can transmit and receive pause frames for flow control (gigabit ports
¡
only).
FC — Supports full-duplex flow control.
¡
Trunk — Indicates whether a port is a member of an aggregated link or trunk.
l
NOTICE: If autonegotiation is disabled for an RJ-45 port, the auto- MDI/MDI-X pin signal configuration is also disabled.

NOTICE: Flow control only works for ports connected to the same internal switch chip (ports 1 to 12 and ports 13 to 24). Cross-chip flow control does
not work.
Example
Console(config)#interface ethernet 1/5
Usage

autonegotiation is disabled.
Enables autonegotiation for a given interface.
Use the no form command to disable autonegotiation.
Advertises the port capabilities of a given interface during
autonegotiation.
Use the no form with parameters command to remove an advertised
capability, or the no form without parameters command to restore
the default values.
