Setting The Ethernet Port Mode; Setting The Link Type For The Ethernet Port - H3C S9500 Series Operation Manual

H3C S9500 Series Routing Switches
Caution:
You cannot enable both broadcast suppression and multicast suppression
simultaneously on the same card. Namely, once you have enabled broadcast
suppression on some ports of a card, you cannot enable multicast suppression on
the other ports of the card, and vice versa.
If multicast suppression is enabled, broadcast packets are also suppressed at the
same time, while broadcast suppression does not work on multicast suppression.
No distinction is made between known multicast and unknown multicast for
multicast suppression.
By default, the broadcast suppression ratio is 50%, while the multicast suppression
ratio is 100%.

2.2.10 Setting the Ethernet Port Mode

Most ports adopt the LAN mode for general data exchange. The port must work in WAN
mode, however, if it needs special frame format for data transfer (such as in fiber
transmission). You can configure network mode available on the port using the
port-mode command.
Perform the following configuration in Ethernet port view.

By default, Ethernet ports works in LAN mode. 10GE Ethernet ports support WAN
mode.

2.2.11 Setting the Link Type for the Ethernet Port

Ethernet port can operate in three different link types, access, hybrid, and trunk types.
The access port carries one VLAN only, used for connecting to the user's computer.
The trunk port can belong to more than one VLAN and receive/send the packets on
multiple VLANs, used for connection between the switches. The hybrid port can also
carry more than one VLAN and receive/send the packets on multiple VLANs, used for
connecting both the switches and user's computers. The difference between the hybrid
port and the trunk port is that the hybrid port allows the packets from multiple VLANs to
