Reference Guide

• The no version of the command resets port-group interfaces to the default Ethernet port mode/speed. Use
the no mode command before you reset the mode on an interface.
• To congure oversubscription on a FC interface, use the speed command.
• To congure breakout interfaces on an Ethernet port, use the interface breakout command.
• To view the currently active ports and subports, use the show interfaces status command.
Example
OS10(conf-pg-1/1/2)# mode FC 16g-2x
OS10(conf-pg-1/1/8)# mode Eth 10g-4x
Example: Reset
mode
OS10(conf-pg-1/1/2)# mode FC 16g-2x
OS10(conf-pg-1/1/2)# no mode
OS10(conf-pg-1/1/2)# mode Eth 10g-4x
Supported Releases 10.3.1E or later
mode l3
After you congure the VLAN scale prole, enables L3 routing on a VLAN.
Syntax
mode l3
Parameters None
Defaults Not congured
Command Mode INTERFACE VLAN
Usage Information To congure the VLAN scale prole, use the scale-profile vlan command. The scale prole globally applies
L2 mode on all VLANs you create and disables L3 transmission. To enable L3 routing trac on a VLAN, use the
mode L3 command.
Example
OS10(config)# interface vlan 10
OS10(conf-if-vl-10)# mode L3
Supported Releases 10.4.0E(X2) or later
mtu
Sets the link maximum transmission unit (MTU) frame size for an Ethernet L2 or L3 interface.
Syntax
mtu value
Parameters value — Enter the maximum frame size in bytes (1280 to 65535).
Default 1532 bytes
Command Mode INTERFACE
Usage Information
To return to the default MTU value, use the no mtu command. If an IP packet includes a Layer 2 header, the IP
MTU must be at least 32 bytes smaller than the L2 MTU.
• Port-channels
– All members must have the same link MTU value and the same IP MTU value.
