Dear Friends,
We are not able to find command for disable FLOW-CONTROL on cisco 7206 router Gig Port (output flow-control is XON, input flow-control is XON).
Cisco_7206#sh int gi0/2
GigabitEthernet0/3 is up, line protocol is up

We want to disable it as input errors are observed on this interface, but dopes'nt find a command for disable this.

Hi
Please refer the below detail to disable flow control.
The negotiation command is applicable only to the Gigabit Ethernet interface of the Cisco 7200-I/O-GE+E. The negotiation auto command is used instead of the duplex and speed commands (which are used on Ethernet and Fast Ethernet interfaces) to automatically configure the duplex and speed settings of the interfaces. The negotiation forced command is used to configure the Gigabit Ethernet interface to be 1000/full-duplex only and to disable flow-control. The Gigabit Ethernet interface of the Cisco 7200-I/O-GE+E is restricted to 1000 Mbps/full duplex only. Autonegotiation only negotiates to these values.
Insted of using negotiation auto you can use negotiation forced.
