I think this is a SNMP::Info issue with Extreme support. Can you test
by replace the existing Extreme.pm in your SNMP::Info with the attached
Extreme.pm? If it fixes the issue, I'll commit it as a permanent fix in
SNMP::Info.
Thanks,
Eric

I have removed the netdisco database and then deployed a fresh one. So
there is no switch in the database which could cause any problem.
I try to discover an extreme switch and get the following errors.
Discovering a cisco switch is working fine. This extreme switch is
discovered well with netdisco 1.3.1
Here what I have done and the output. Can you help me?
Regards
Peter

SNMP::Info::Layer3::Extreme - Perl5 Interface to Extreme Network Devices
=head1 AUTHOR
Eric Miller, Bill Fenner
=head1 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";

=head1 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.

These are methods that return tables of information in the form of a reference
to a hash.
=head2 Overrides
=over
=item $extreme->interfaces()
Returns a mapping between the Interface Table Index (iid) and the physical
port name.
=item $extreme->i_duplex()
Parses mau_index and mau_link to return the duplex information for
interfaces.
=item $extreme->i_duplex_admin()
Parses C<mac_index>,C<mau_autostat>,C<mau_type_admin> in
order to find the admin duplex setting for all the interfaces.
Returns either (auto,full,half).
=item $extreme->i_ignore()
Returns reference to hash. Increments value of IID if port is to be ignored.
Ignores VLAN meta interfaces and loopback
=item $extreme->fw_mac()
(C<extremeFdbMacFdbMacAddress>)
=item $extreme->fw_port()
(C<extremeFdbMacFdbPortIfIndex>)
=item $extreme->fw_status()
(C<extremeFdbMacFdbStatus>)
=item $extreme->lldp_if()
Returns the mapping to the SNMP Interface Table. Extreme LLDP uses the
bridge index rather than ifIndex.
=item $extreme->i_vlan()
Returns a mapping between C<ifIndex> and the VLAN.
=item $extreme->i_vlan_membership()
Returns reference to hash of arrays: key = C<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";
}
=item $extreme->v_index()
Returns VLAN IDs
=item $extreme->v_name()
Returns VLAN names
(C<extremeVlanIfDescr>)
=item $extreme->bp_index()
Returns reference to hash of bridge port table entries map back to interface
identifier (iid)
Returns (C<ifIndex>) for both key and value since we're using
F<EXTREME-FDB-MIB> rather than F<BRIDGE-MIB>.
=item $extreme->peth_port_power()
Power supplied by PoE ports, in milliwatts
(C<extremePethPortMeasuredPower>)
=item $extreme->peth_power_watts()
The configured maximum amount of in-line power available to the slot.
(C<extremePethSlotPowerLimit>)

These are methods that provide SNMP set functionality for overridden methods
or provide a simpler interface to complex set operations. See
L<SNMP::Info/"SETTING DATA VIA SNMP"> for general information on set
operations.
=over
=item $extreme->set_i_vlan ( vlan, ifIndex )
Changes an access (untagged) port VLAN, must be supplied with the numeric
VLAN ID and port C<ifIndex>. This method should only be used on end station
(non-trunk) ports.
Example:
my %if_map = reverse %{$extreme->interfaces()};
$extreme->set_i_vlan('2', $if_map{'FastEthernet0/1'})
or die "Couldn't change port VLAN. ",$extreme->error(1);
=item $extreme->set_i_pvid ( pvid, ifIndex )
Sets port default VLAN, must be supplied with the numeric VLAN ID and
port C<ifIndex>. This method should only be used on trunk ports.
Example:
my %if_map = reverse %{$extreme->interfaces()};
$extreme->set_i_pvid('2', $if_map{'FastEthernet0/1'})
or die "Couldn't change port default VLAN. ",$extreme->error(1);
=item $extreme->set_add_i_vlan_tagged ( vlan, ifIndex )
Adds the VLAN to the enabled VLANs list of the port, must be supplied with the
numeric VLAN ID and port C<ifIndex>.
Example:
my %if_map = reverse %{$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);
=item $extreme->set_remove_i_vlan_tagged ( vlan, ifIndex )
Removes the VLAN from the enabled VLANs list of the port, must be supplied
with the numeric VLAN ID and port C<ifIndex>.
Example:
my %if_map = reverse %{$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);
=back
=head1 Data Munging Callback Subroutines
=over
=item $extreme->munge_power_stat()
Removes 'present' and changes 'not' to 'Not' in the front of a string.
=item $extreme->munge_true_ok()
Replaces 'true' with "OK" and 'false' with "Not OK".
