NAME ^

SNMP::Info::Layer3::Extreme - Perl5 Interface to Extreme Network Devices

AUTHOR ^

Eric Miller, Bill Fenner

SYNOPSIS ^

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

 my $class      = $extreme->class();

 print "SNMP::Info determined this device to fall under subclass : $class\n";

DESCRIPTION ^

Provides abstraction to the configuration information obtainable from an Extreme device through SNMP.

For speed or debugging purposes you can call the subclass directly, but not after determining a more specific class using the method above.

my $extreme = new SNMP::Info::Layer3::Extreme(...);

TABLE METHODS ^

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

Overrides

$extreme->interfaces()

Returns a mapping between the Interface Table Index (iid) and the physical port name.

$extreme->i_duplex()

Parses mau_index and mau_link to return the duplex information for interfaces.

$extreme->i_duplex_admin()

Parses mac_index,mau_autostat,mau_type_admin in order to find the admin duplex setting for all the interfaces.

Returns either (auto,full,half).

$extreme->i_ignore()

Returns reference to hash. Increments value of IID if port is to be ignored.

Ignores VLAN meta interfaces and loopback

$extreme->fw_mac()

(extremeFdbMacFdbMacAddress)

$extreme->fw_port()

(extremeFdbMacFdbPortIfIndex)

$extreme->fw_status()

(extremeFdbMacFdbStatus)

$extreme->i_vlan()

Returns a mapping between ifIndex and the VLAN.

$extreme->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 = $extreme->interfaces();
  my $vlans      = $extreme->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";
  }
$extreme->v_index()

Returns VLAN IDs

$extreme->v_name()

Returns VLAN names

(extremeVlanIfDescr)

$extreme->bp_index()

Returns reference to hash of bridge port table entries map back to interface identifier (iid)

Returns (ifIndex) for both key and value since we're using EXTREME-FDB-MIB rather than BRIDGE-MIB.

$extreme->peth_port_power()

Power supplied by PoE ports, in milliwatts ("extremePethPortMeasuredPower")

Topology information

Based upon the firmware version Extreme devices may support Extreme Discovery Protocol (EDP), Link Layer Discovery Protocol (LLDP), or both. These methods will query both and return the combination of all information. As a result, there may be identical topology information returned from the two protocols causing duplicate entries. It is the calling program's responsibility to identify any duplicate entries and remove duplicates if necessary.

$extreme->hasCDP()

Returns true if the device is running either EDP or LLDP.

$extreme->c_if()

Returns reference to hash. Key: iid Value: local device port (interfaces)

$extreme->c_ip()

Returns reference to hash. Key: iid Value: remote IPv4 address

If multiple entries exist with the same local port, c_if(), with the same IPv4 address, c_ip(), it may be a duplicate entry.

With EDP multiple entries may exist with the same local port, c_if(), and different IPv4 addresses, c_ip(), as EDP reports addresses for each VLAN transported across the trunk. In the case of LLDP with multiple addresses there is either a non-LLDP device in between two or more devices or multiple devices which are not directly connected.

Use the data from the Layer2 Topology Table below to dig deeper.

$extreme->c_port()

Returns reference to hash. Key: iid Value: remote port (interfaces)

$extreme->c_id()

Returns reference to hash. Key: iid Value: string value used to identify the chassis component associated with the remote system.

$extreme->c_platform()

Returns reference to hash. Key: iid Value: Remote Device Type

This information is only available from LLDP. EDP does not provide an equivalent.

SET METHODS ^

These are methods that provide SNMP set functionality for overridden methods or provide a simpler interface to complex set operations. See "SETTING DATA VIA SNMP" in SNMP::Info for general information on set operations.

$extreme->set_i_vlan ( vlan, ifIndex )

Changes an access (untagged) port VLAN, must be supplied with the numeric VLAN ID and port ifIndex. This method should only be used on end station (non-trunk) ports.

  Example:
  my %if_map = reverse %{$extreme->interfaces()};
  $extreme->set_i_vlan('2', $if_map{'FastEthernet0/1'}) 
    or die "Couldn't change port VLAN. ",$extreme->error(1);
$extreme->set_i_pvid ( pvid, ifIndex )

Sets port default VLAN, must be supplied with the numeric VLAN ID and port ifIndex. This method should only be used on trunk ports.

  Example:
  my %if_map = reverse %{$extreme->interfaces()};
  $extreme->set_i_pvid('2', $if_map{'FastEthernet0/1'}) 
    or die "Couldn't change port default VLAN. ",$extreme->error(1);
$extreme->set_add_i_vlan_tagged ( vlan, ifIndex )

Adds the VLAN to the enabled VLANs list of the port, must be supplied with the numeric VLAN ID and port ifIndex.

  Example:
  my %if_map = reverse %{$extreme->interfaces()};
  $extreme->set_add_i_vlan_tagged('2', $if_map{'FastEthernet0/1'}) 
    or die "Couldn't add port to egress list. ",$extreme->error(1);
$extreme->set_remove_i_vlan_tagged ( vlan, ifIndex )

Removes the VLAN from the enabled VLANs list of the port, must be supplied with the numeric VLAN ID and port ifIndex.

  Example:
  my %if_map = reverse %{$extreme->interfaces()};
  $extreme->set_remove_i_vlan_tagged('2', $if_map{'FastEthernet0/1'}) 
    or die "Couldn't add port to egress list. ",$extreme->error(1);

Data Munging Callback Subroutines ^

$extreme->munge_power_stat()

Removes 'present' and changes 'not' to 'Not' in the front of a string.

$extreme->munge_true_ok()

Replaces 'true' with "OK" and 'false' with "Not OK".
