• 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 Supported Releases 10.3.1E or later mode l3 Enables L3 routing on a VLAN after you configure the VLAN scale profile.

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.
