|
|
|
|
Abstraction subclass for Nortel Alteon Series Layer 2-7 load balancing
|
|
switches and Nortel BladeCenter Layer2-3 GbE Switch Modules.
|
|
|
|
For speed or debugging purposes you can call the subclass directly, but not
|
|
after determining a more specific class using the method above.

|
|
copperModule/fiberModule with BladeCenter GbESM.

|
|
|
|
=item $alteon->interfaces()
|
|
|
|
Returns reference to the map between IID and physical port.
|
|
|
|
Utilizes description for network interfaces. Ports are determined by
|
|
formula (C<ifIndex mod 256>).
|
|
|
|
=item $alteon->i_duplex()
|
|
|
|
Returns reference to hash. Maps port operational duplexes to IIDs.
