Duplex; Flag Sdh - H3C S12500 Series Manual

Field
Packets dropped due to unicast-suppression
Packets dropped due to multicast-suppression
Packets dropped due to Tx packet aging

duplex

Use duplex to set the duplex mode for an Ethernet interface.
Use undo duplex to restore the default duplex mode of the Ethernet interface.
Syntax
duplex { auto | full | half }
undo duplex
Default
A 10-GE interface operates in full duplex mode, and all other types of Ethernet interfaces operate in
autonegotiation mode.
Views
Ethernet interface view
Predefined user roles
network-admin
mdc-admin
Parameters
auto: Configures the interface to autonegotiate the duplex mode with the peer.
full: Configures the interface to operate in full duplex mode, so that the interface can receive and transmit
packets at the same time.
half: Configures the interface to operate in half duplex mode, so that the interface can only receive or
only transmit packets at one time. Fiber ports do not support the keyword.
Examples
# Configure interface GigabitEthernet 3/0/1 to operate in full duplex mode.
<Sysname> system-view
[Sysname] interface GigabitEthernet 3/0/1
[Sysname-GigabitEthernet3/0/1] duplex full

flag sdh

Use flag sdh to set the value for the overhead byte J0 or J1 in SDH frames when the 10-GE interface
operates in WAN mode.
Use undo flag sdh to restore the default value of the J0 or J1 byte.
Description
Packets that are dropped due to unknown unicast
suppression.
Packets that are dropped due to multicast
suppression.
Outbound packets that are timed out.
