Configuring Slots and Ports on a Switch
ExtremeWare XOS 11.3 Concepts Guide

The 1 Gbps ports both advertise support and respond to pause frames, but they do not initiate pause
frames. The 10 Gbps ports support flow control, and both types of ports initiate and respond to pause
frames. ExtremeWare XOS does not support turning off autonegotiation on the management port.
Beginning with ExtremeWare XOS 11.1, the 10 Gbps ports support the Link Fault Signal (LFS) function.
This function, which is always enabled, monitors the 10 Gbps ports and indicates either a remote fault
or a local fault. The system then stops transmitting or receiving traffic from that link. Once the fault is
alleviated, the system puts the link back up and the traffic automatically resumes.
The Extreme Networks implementation of LFS conforms to the IEEE standard 802.3ae-2002.
NOTE
On the BlackDiamond 10K switch, the 10 Gbps module must have the serial number 804405-00-09 or higher to
support LFS. To display the serial number of the module, issue the
show slot <slot_number>
command. (All
the modules on the BlackDiamond 8800 family of switches support LFS.)
Although the physical link remains up, all Layer 2 and above traffic stops. The system sends LinkDown
and LinkUp traps when these events occur. Additionally, the system writes one or more information
messages to the syslog, as shown in the following example:
09/09/2004 14:59:08.03 <Info:vlan.dbg.info> MSM-A: Port 4:3 link up at
10 Gbps speed and full-duplex
09/09/2004 14:59:08.02 <Info:hal.sys.info> MSM-A: 4:3 - remote fault
recovered.
09/09/2004 14:59:05.56 <Info:vlan.dbg.info> MSM-A: Port 4:3 link down
due to remote fault
09/09/2004 14:59:05.56 <Info:hal.sys.info> MSM-A: 4:3 - remote fault.
09/09/2004 15:14:12.22 <Info:hal.sys.info> MSM-A: 4:3 - local fault
recovered.
09/09/2004 15:14:11.35 <Info:vlan.dbg.info> MSM-A: Port 4:3 link up at
10 Gbps speed and full-duplex
09/09/2004 15:13:33.56 <Info:vlan.dbg.info> MSM-A: Port 4:3 link down
due to local fault
09/09/2004 15:13:33.56 <Info:hal.sys.info> MSM-A: 4:3 - local fault.
09/09/2004 15:13:33.49 <Info:vlan.dbg.info> MSM-A: Port 4:3 link down
due to local fault
NOTE
A link down or up event may trigger Spanning Tree Protocol topology changes or transitions.
Turning Off Autonegotiation on a Gigabit Ethernet Port
In certain interoperability situations, you may need to turn autonegotiation off on a fiber gigabit
Ethernet port. Although a gigabit Ethernet port runs only at full duplex, you must specify the duplex
setting.
The following example turns autonegotiation off for port 1 (a 1 Gbps Ethernet port) on a module
located in slot 1 of a modular switch:
