Enabling LFS
To enable LFS between two 10 Gbps Ethernet devices, enter commands such as the following on
both ends of the link.
PowerConnect(config)#interface e 1
PowerConnect(config-if-e10000-1)#link-fault-signal
Syntax: link-fault-signal
LFS is OFF by default.
Jumbo frame support
Ethernet traffic moves in units called frames. The maximum size of frames is called the Maximum
Transmission Unit (MTU). When a network device receives a frame larger than its MTU, the data is
either fragmented or dropped. Historically, Ethernet has a maximum frame size of 1500 bytes, so
most devices use 1500 as their default MTU.
Jumbo frames are Ethernet frames with more than 1,500 bytes MTU. Conventionally, jumbo
frames can carry up to 9,000 bytes MTU. PowerConnect devices also support jumbo frames per
VLAN.
