Configuring The Dual Fiber Repeater Module - IBM Nways 8260 Manual

9.6.1 Configuring the Dual Fiber Repeater Module

To configure this module you must do the following:
1. Set beacon threshold for the module.
2. Enable/disable static switch for each lobe port.
3. Assign ports to network segments.
4. Assign RI/RO trunk ports to network segments.
5. Set compatibility mode for the trunk ports.
6. Enable/disable trunks.

When a beaconing condition is detected on a lobe port, the port is wrapped
by the Recovery ASIC. The port is unwrapped when a transition of phantom
is detected or when the port disabled and then re-enabled by the user.
The number of times that a phantom transition is allowed to cause a port to
unwrap is determined by the bcn_threshold parameter which can be set for
each module using the following command:
SET MODULE {slot.port} BCN_THRESHOLD {0-255}
Once the threshold is exceeded, the port or trunk remains wrapped until the
user disables and re-enables the port. While wrapped, the port status is
BCN THRES EXCEEDED .
Note: The bcn_threshold is reset whenever a port successfully inserts into
the ring, or the module is reset.
If you want the user of a port to power down the station before that port can
be switched to another network segment, you must enable the static_switch
for the specified port using the following command:
SET PORT {slot.port} STATIC_SWITCH {enable}
For more information about static_switch please refer to 8.6.2, "Static Switch
on the Per-Port Switching Modules" on page 145.
Note: Trunk ports can be switched between different segments at any time.
Use the following command to assign each port on the module to one of the
backplane segments or isolated segments on the module:
SET PORT {slot.port} NETWORK {network}
You can assign RI/RO trunk ports to a network using the following command:
SET TRUNK {slot} RING_IN.n NETWORK {network} or
SET TRUNK {slot} RING_OUT.n NETWORK {network}
In this command n is used to specify the set of RI/RO trunks for which this
command is issued.
Note: If you assign a RING_IN (or RING_OUT) trunk to a segment, the other
trunk within that set will automatically be assigned to the same segment.
Depending on the hub to which the trunk is attached you must set the
compatibility mode as described in 9.3.1, "Configuring the 18-Port Active
Per-Port Switching Module" on page 177.
To set the compatibility mode for a trunk, you can use the following
command:
SET TRUNK {slot} RING_IN.n COMPATIBILITY_MODE {mode} or
SET TRUNK {slot} RING_OUT.n COMPATIBILITY_MODE {mode}
specifies the top and specifies the bottom set.
