API Guide

● QSFP28-DD port groups 10 to 12 operate in 2x100GE mode.
● QSFP28 port groups 13 and 14 operate in 1x100GE mode.
● Unified port groups 15 and 16 operate in ethernet 1x100GE mode.
Command Mode PORT-GROUP
Usage
Information
● The mode {FC | Eth} command configures a port group to operate at line rate and guarantees no
traffic loss.
● To configure oversubscription on a FC interface, use the speed command.
● To view the currently active ports and subports, use the show interfaces status command.
● 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.
Example
OS10(conf-pg-1/1/2)# mode FC 16g-4x
OS10(conf-pg-1/1/8)# mode Eth 10g-4x
Example: Reset
mode
OS10(conf-pg-1/1/2)# mode FC 16g-4x
OS10(conf-pg-1/1/2)# no mode
OS10(conf-pg-1/1/2)# mode Eth 10g-4x

mode l3
Enables L3 routing on a VLAN after you configure the VLAN scale profile.
Syntax
mode l3
Parameters None
Defaults Not configured
Command Mode INTERFACE VLAN
Usage
Information
To configure the VLAN scale profile, use the scale-profile vlan command. The scale profile
globally applies L2 mode on all VLANs you create and disables L3 transmission. To enable L3 routing
traffic 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, from 1280 to 65535. Maximum frame size for an
S3000-ON is 12000, and S4000-ON is 9216.
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 L2 header, the
IP MTU must be at least 32 bytes smaller than the L2 MTU.
