Perform the following configuration in Ethernet interface view.
When an Ethernet interface is configured with two or more IP addresses, use the
keyword
keyword
"sub"
to identify the second one and those behind it (that is, the
secondary IP addresses).
Configuring MTU
The configuration of MTU can affect the fragment and reassembly of IP packets.
Perform the following configuration in Ethernet interface view.
The frame format defaults to Ethernet_II and MTU size is in the range of 46 to
1500 bytes.
1500 bytes.
Selecting operating speed of FE interface
As mentioned earlier, an FE interface can work at both 10 Mbps and 100 Mbps.
Perform the following configuration in Ethernet interface view to select the
operating speed of the interface.
Perform the following configuration in Ethernet interface view to select the
operating speed of the interface.
By default,
negotiation
is selected, i.e., the system automatically chooses an

by force, but the speed thus specified must be the same as one of the connected
network.
