Table 48. Port groups and breakout modes on the S5296F-ON switch (continued)
Port Group Ports Supported breakout modes
● 25g-4x
● 10g-4x
To configure breakout modes:
1. Configure a port group in CONFIGURATION mode. Enter 1/1 for node/slot and the port group number.
port-group node/slot/port-group
2. Configure the breakout mode in PORT-GROUP mode.
mode Eth breakout-mode
● 100g-2x — Split a port group into two 100GE interface.
● 100g-1x — Set a port group to 100GE mode.
● 50g-4x — Split a port group into four 50GE interfaces.
● 50g-2x — Split a port group into two 50GE interfaces.
● 40g-2x — Split a port group into two 40GE interfaces for use with a QSFP+ 40GE transceiver.
● 40g-1x — Set a port group to 40GE mode for use with a QSFP+ 40GE transceiver.
● 25g-8x — Split a port group into eight 25GE interfaces.
● 25g-4x — Split a port group into four 25GE interfaces.
● 10g-8x — Split a port group into eight 10GE interfaces.
● 10g-4x — Split a port group into four 10GE interfaces.
3. Return to CONFIGURATION mode.

4. Enter Interface breakout mode to configure other settings, such as, speed.
interface ethernet node/slot/port[:subport]
The following shows converting a port group from 25g-4x mode to 10g-4x mode:
OS10# configure terminal
OS10(config)# port-group 1/1/1
OS10(conf-pg-1/1/1)# mode Eth 10g-4x
OS10(conf-pg-1/1/1)# exit
OS10(config)# interface ethernet 1/1/1:1
OS10(conf-if-eth1/1/1:1)# speed
1000 Set speed to 1000 Mbps
10000 Set speed to 10000 Mbps
auto Automatic Settings (default)
OS10(conf-if-eth1/1/1:1)# speed 1000
L2 mode configuration
Each physical Ethernet interface uses a unique MAC address. Port-channels and VLANs use a single MAC address. By default,
all the interfaces operate in L2 mode. From L2 mode you can configure switching and L2 protocols, such as VLANs and
Spanning-Tree Protocol (STP) on an interface.
Enable L2 switching on a port interface in Access or Trunk mode. By default, an interface is configured in Access mode. Access
mode allows L2 switching of untagged traffic on a single VLAN (VLAN 1 is the default). Trunk mode enables L2 switching of
untagged traffic on the Access VLAN, and tagged traffic on one or more VLANs.
By default, native VLAN of a port is the default VLAN ID of the switch. You can change the native VLAN using the
switchport access vlan vlan-id command.
A Trunk interface carries VLAN traffic that is tagged using 802.1q encapsulation. If an Access interface receives a packet with
an 802.1q tag in the header that is different from the Access VLAN ID, it drops the packet.
