Configuring Auto-Negotiation

By default, auto-negotiation is enabled all Gigabit Ethernet interface. You can enable or disable
auto-negotiation for a specified Gigabit Ethernet interface. When auto-negotiation is enabled, the port
automatically detects the speed or pause method, and duplex of incoming signals based on the link
partner. You can also detect link up conditions using the auto-negotiation feature.
To configure auto-negotiation, follow these steps:
Command
Step 1
switch# config terminal
switch(config)#
Step 2
switch(config)# interface gigabitethernet 2/2
switch(config-if)#
Step 3
switch(config-if)# switchport auto-negotiate
switch(config-if)# no switchport
auto-negotiate

Configuring the MTU Frame Size

You can configure the interfaces on a switch to transfer large (or jumbo) frames on a port. The default
IP maximum transmission unit (MTU) frame size is 1500 bytes for all Ethernet ports. By configuring
jumbo frames on a port, the MTU size can be increased up to 9000 bytes.
The minimum MTU size is 576 bytes.
Note
Tip MTU changes are disruptive, all FCIP links and iSCSI sessions flap when the software detects a change
in the MTU size.
You do not need to explicitly issue the shutdown and no shutdown commands.
To configure the MTU frame size, follow these steps:
Command
Step 1
switch# config terminal
switch(config)#
Step 2
switch(config)# interface gigabitethernet 2/2
switch(config-if)#
Step 3
switch(config-if)# switchport mtu 3000
