This command removes the flow control feature from the interface(s).
Format no flowcontrol
Mode Global Config, Interface Config
5.2.1.14.6. mtu
Use the mtu command to set the maximum transmission unit (MTU) size, in bytes, for frames that ingress or
egress the interface. You can use the mtu command to configure jumbo frame support for physical and port-
channel (LAG) interfaces. For the standard ICOS implementation, the MTU size is a valid integer between 1522
and 9412 for tagged packets and a valid integer between 1518 and 9412 for untagged packets.
Format mtu <1518-9412>
Default 1518
Mode Interface Config
5.2.1.14.7. no mtu
This command sets the default MTU size (in bytes) for the interface.
Format no mtu
Mode Interface Config
5.2.1.14.8. port-mode
Use this command to configure a 100G QSFP28 port in either 1x100G, 1x40G, 2x50G, 4x25G, or 4x10G mode or
four 25G SFP28 ports in either 4x25G, 4x10G, or 4x1G mode.
Note: In model M4500-48XF8C, every four 25G ports form a group from port 1 until port 48. The port-mode
command can only be applied on the first port of each group and all the four ports in the same group are
configured to the same speed. For example, you can issue the port-mode 4x1G command on ethernet port 0/1
but not on ethernet port 0/2, 0/3, or 0/4; all the four ports from 0/1 to 0/4 are configured to 1G.
Format port-mode {1x100G | 1x40G | 2x50G | 4x25G | 4x10G | 4x1G}
