SYNOPSIS

 # Let SNMP::Info determine the correct subclass for you. 
 my $alteon = new SNMP::Info(
                          AutoSpecify => 1,
                          Debug       => 1,
                          DestHost    => 'myswitch',
                          Community   => 'public',
                          Version     => 2
                        ) 
    or die "Can't connect to DestHost.\n";

 my $class      = $alteon->class();
 print "SNMP::Info determined this device to fall under subclass : $class\n";

DESCRIPTION

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.

 my $alteon = new SNMP::Info::Layer3::AlteonAD(...);

See "Required MIBs" in SNMP::Info::Layer3 for its own MIB requirements.

GLOBALS

These are methods that return scalar value from SNMP

$alteon->model()

Returns model type. Checks $alteon->id() against the ALTEON-ROOT-MIB and then parses out aceswitch, replaces acedirector with AD, and replaces copperModule/fiberModule with BladeCenter GbESM.

$alteon->vendor()

Returns 'nortel'

$alteon->os()

Returns 'alteon'

$alteon->os_ver()

Returns the software version reported by agSoftwareVersion

$alteon->tftp_action()

(agTftpAction)

$alteon->tftp_host()

(agTftpServer)

$alteon->tftp_file()

(agTftpCfgFileName)

$alteon->tftp_result()

(agTftpLastActionStatus)

TABLE METHODS

These are methods that return tables of information in the form of a reference to a hash.

Overrides

$alteon->interfaces()

Returns reference to the map between IID and physical port.

Utilizes description for network interfaces. Ports are determined by formula (ifIndex mod 256).

$alteon->i_duplex()

Returns reference to hash. Maps port operational duplexes to IIDs.

$alteon->i_duplex_admin()

Returns reference to hash. Maps port admin duplexes to IIDs.

$alteon->i_vlan()

Returns a mapping between ifIndex and the PVID or default VLAN.

$alteon->i_vlan_membership()

Returns reference to hash of arrays: key = ifIndex, value = array of VLAN IDs. These are the VLANs which are members of the egress list for the port.

  Example:
  my $interfaces = $alteon->interfaces();
  my $vlans      = $alteon->i_vlan_membership();
  
  foreach my $iid (sort keys %$interfaces) {
    my $port = $interfaces->{$iid};
    my $vlan = join(',', sort(@{$vlans->{$iid}}));
    print "Port: $port VLAN: $vlan\n";
  }

$alteon->v_index()

Returns VLAN IDs

$alteon->v_name()

Human-entered name for vlans.

$alteon->i_name()

Maps (agPortCurCfgPortName) to port and returns the human set port name if exists.

$alteon->bp_index()

Returns a mapping between ifIndex and the Bridge Table.
