Interfaces and Subnets

When you first create an 

ethernet

 object you will see that none of the attribute checkboxes are ticked, and

the defaults described above apply. Ensure that you set the 

port

 attribute value correctly to modify the port

you intended to.

6.4.1. Disabling auto-negotiation

If you are connecting a port to a link-partner that does not support auto-negotiation (or has it disabled), it is
advisable  to  disable  auto-negotiation  on  the  FB2700  port.  To  do  this,  tick  the  checkbox  for  the 

autoneg

attribute and select 

false

 from the drop-down box. You will then need to set port speed and duplex mode

manually (see below) to match the link-partner settings.

6.4.2. Setting port speed

If auto-negotiation is enabled, the FB2700 port will normally advertise that it is capable of link-speeds of 10Mb/
s, 100Mb/s or 1Gb/s - if you have reason to restrict the possible link-speed to one of these values you can set
the 

speed

 attribute to 10M, 100M or 1G. This will cause the port to only advertise the specified speed - if the

(auto-negotiate capable) link-partner does not support that speed, the link will fail to establish.

If auto-negotiation is disabled, the 

speed

 attribute simply sets the port's speed.

6.4.3. Setting duplex mode

If auto-negotiation is enabled, the FB2700 port will normally advertise that it is capable of either half- or full-
duplex operation modes - if you have reason to restrict the operation to either of these modes, you can set the

duplex

 attribute to either 

half

 or 

full

. This will cause the port to only advertise the specified mode - if

the (auto-negotiate capable) link-partner does not support that mode, the link will fail to establish.

If auto-negotiation is disabled, the 

duplex

 attribute simply sets the port's duplex mode.

Note

If  you  do  not  set  the 

autoneg

  attribute  (checkbox  is  unticked),  and  you  set  both  port  speed  and

duplex mode to values other than 

auto

, auto-negotiation will be disabled ; this behaviour is to reduce

the  potential  for  duplex  mis-match  problems  that  can  occur  when  connecting  the  FB2700  to  some
vendors' (notably Cisco) equipment that has auto-negotation disabled by default.

6.4.4. Defining port LED functions

For each port, the green and yellow port LEDs can be set to indicate any of the conditions shown in Table 6.1,
by setting the values of the 

green

 and/or 

yellow

 attributes.

Table 6.1. Port LED functions
