Link Trap. Select whether or not to send a trap when link status changes. The factory 
default is Enable.
-     
Enable. Specifies that the system sends a trap when the link status changes.
-     
Disable. Specifies that the system does not send a trap when the link status 
changes.
Maximum Frame Size. Specify the maximum Ethernet frame size the interface 
supports. The size includes the Ethernet header, CRC, and payload. Any change to 
the maximum frame size is immediately applied to all interfaces. 
MAC Address. The physical address of the specified interface.
PortList Bit Offset. The bit offset value that corresponds to the port when the MIB 
object type PortList is used to manage in SNMP.
ifIndex. The ifIndex of the interface table entry associated with this port. If the 
interface field is set to All, this field is blank.

Flow Control
IEEE 802.3x flow control works by pausing a port when the port becomes oversubscribed 
and dropping all traffic for small bursts of time during the congestion condition. This can lead 
to high-priority and network control traffic loss. When IEEE 802.3x flow control is enabled, 
lower-speed switches can communicate with higher-speed switches by requesting that the 
higher-speed switch refrains from sending packets. Transmissions are temporarily halted to 
prevent buffer overflows.
To configure global flow control settings: 
1.
Select Switching 
>
 Ports > Flow Control.
2.
Next to Global Flow Control (IEEE 802.3x) Mode, enable or disable IEEE 802.3x flow control 
on the system.
Enable. The switch sends pause packets if the port buffers become full.
Disable. The switch does not send pause packets if the port buffers become full.
