To configure link negotiation on a port, perform this task:
Command
Step 1
Router(config)# interface gigabitethernet
slot/port
Step 2
Router(config-if)# speed nonegotiate
Router(config-if)# no speed nonegotiate
This example shows how to enable link negotiation on Gigabit Ethernet port 5/4:
Router(config)# interface gigabitethernet 5/4
Router(config-if)# no speed nonegotiate
Displaying the Speed and Duplex Mode Configuration
To display the speed and duplex mode configuration for a port, perform this task:
Command
Router# show interfaces type
1. type = ethernet, fastethernet, gigabitethernet, or tengigabitethernet
This example shows how to display the speed and duplex mode of Fast Ethernet port 5/4:
Router# show interfaces fastethernet 5/4
FastEthernet5/4 is up, line protocol is up
Hardware is Cat6K 100Mb Ethernet, address is 0050.f0ac.3058 (bia 0050.f0ac.3058)
MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec,
Encapsulation ARPA, loopback not set
Keepalive set (10 sec)
Full-duplex, 100Mb/s
ARP type: ARPA, ARP Timeout 04:00:00
Last input 00:00:33, output never, output hang never
Last clearing of "show interface" counters never
Queueing strategy: fifo
Output queue 0/40, 0 drops; input queue 0/75, 0 drops
5 minute input rate 0 bits/sec, 0 packets/sec
5 minute output rate 0 bits/sec, 0 packets/sec
