Port-channels
All members must have the same link MTU value and the same IP MTU value.
The port channel link MTU and IP MTU must be less than or equal to the link MTU and IP MTU
values you configure on the channel members. For example, if the members have a link MTU of
2100 and an IP MTU 2000, the port channels MTU values cannot be higher than 2100 for link MTU
or 2000 bytes for IP MTU.
VLANS
All members of a VLAN must have same IP MTU value.
Members can have different link MTU values. Tagged members must have a link MTU four bytes
higher than untagged members to account for the packet tag.
The VLAN link MTU and IP MTU must be less than or equal to the link MTU and IP MTU value
you configure on the VLAN members. For example, the VLAN contains tagged members with a link
MTU of 1522 and IP MTU of 1500 and untagged members with link MTU of 1518 and IP MTU of
1500. The VLANs link MTU cannot be higher than 1518 bytes and its IP MTU cannot be higher
than 1500 bytes.
Example
OS10(conf-if-eth1/1/7)# mtu 3000
Supported
Releases
10.2.0E or later
port mode Eth
Configures a Z9264F-ON QSFP28 port group to operate in Ethernet mode, with the specified speed on activated interfaces.
Syntax
port node/slot/port mode Eth port-mode
Parameters
node/slot/port Enter the interface type details.
mode Eth Configure a port group in Ethernet mode and set the speed to:
100g-1x Reset a port to 100GE mode.
50g-2x Split a port into two 50GE interfaces.
40g-1x Set a port to 40GE mode for use with a QSFP+ 40GE transceiver.
25g-4x Split a port into four 25GE interfaces.
10g-4x Split a port into four 10GE interfaces.
Default 100g-1x
Command mode PORT-GROUP
Usage
information
To view the currently active ports and subports, use the show port-group command. The no version
of the command resets port-group interfaces to the default Ethernet port mode/speed.
Example
OS10(config)# port-group 1/1/2
OS10(conf-pg-1/1/2)# profile restricted
OS10(conf-pg-1/1/2)# port 1/1/3 mode Eth 25g-4x
OS10(conf-pg-1/1/2)# exit
OS10(config)# interface ethernet 1/1/3:2
OS10(conf-if-eth1/1/3:2)#
Supported
releases
10.4.3.0 or later
port-group
Configures a group of front-panel unified ports, or a double-density QSFP28 (QSFP28-DD) or single-density QSFP28 port
group.
Syntax
