or Disabled. If SFP is selected as the connector, the speed setting is defined by the SFP that
has been inserted. Press the Space bar to view the available options.
RMTF Remote Fault (RMTF) allows an alarm to be transmitted to the link partner to indicate loss
of signal on receive. When a link loss is detected, the port stops transmitting service traffic on the
port and begins to transmit the Remote Fault signal so the connected link knows the link is no
longer operational. RMTF is only available on optical (SFP) ports. A port that is receiving Remote
Fault is treated as if the link is down for purposes of Link Loss Forwarding and alarming. Even
though the link is still up, only Remote Fault is being received and service traffic is not flowing.
Once the link fault is corrected, Remote Fault transmission is automatically terminated and
service traffic flow will resume. Press the Space bar to select User Port Enabled, Net Port
Enabled, Both Ports Enabled, or Disabled.
GigE RMTF Mode In CP Proprietary mode, the CPU changes the speed from 1G to 100M to
indicate a remote fault. In Negotiation mode, the CPU advertises the remote fault in auto
negotiation.
LLF Enables or disables Link Loss Forwarding (LLF). Link Loss Forwarding allows the 9145E to
signal attached equipment that a link has gone down by bringing down the attached link. Press
the Space bar to select User->Network, Network->User, Both Directions, or Disabled.
• If you select User > Network, if the User Port link is down, the Network Port will be dis-
abled.
• If you select Network > User, the User Port will be disabled if the Network Port goes
down.
• If you select Both Directions, either port can bring down the other port. LLF can only be
active in one direction at a time When the original link is restored, the partner link is also
restored.
Flow Control Enables or disables flow control on the ports. Flow control is used for 9145Es that
have a speed mismatch between the user port and the network port and are attached to
equipment which can buffer overflow traffic. If Flow Control is enabled, the 9145E will begin to
transmit PAUSE frames when its buffers are 3/4ths full. Press the Space bar to select User Port
Enabled, Net Port Enabled, Both Ports Enabled, or Disabled.
Maximum Frame Size Sets the maximum allowable Ethernet Frame size the 9145E will forward
for both ports. Frames exceeding the Maximum Frame Size will be counted as Oversize Packets
and will be discarded. Frames destined for the 9145E Manager are exempt from the limit. Enter
the Maximum Frame Size between 1518 and 10000.
