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->lldp_if()

Returns the mapping to the SNMP Interface Table. Extreme LLDP uses the bridge index rather than ifIndex.

$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->i_vlan_membership_untagged()

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

$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")

$extreme->peth_power_watts()

The configured maximum amount of in-line power available to the slot.

("extremePethSlotPowerLimit")

Spanning Tree Instance Globals

$extreme->stp_i_mac(): Returns the MAC extracted from ("extremeStpDomainBridgeId").
$extreme->stp_i_id(): Returns the unique identifier of the STP domain.
("extremeStpDomainStpdInstance")
$extreme->stp_i_time(): Returns time since last topology change detected. (100ths/second)
("extremeStpDomainTimeSinceTopologyChange")
$extreme->stp_i_time(): Returns time since last topology change detected. (100ths/second)
("extremeStpDomainTimeSinceTopologyChange")
$extreme->stp_i_time(): Returns the total number of topology changes detected.
("extremeStpDomainTopChanges")
$extreme->stp_i_root(): Returns root of STP.
("extremeStpDomainDesignatedRoot")
$extreme->stp_i_root_port(): Returns the port number of the port that offers the lowest cost path to the root bridge.
("extremeStpDomainRootPortIfIndex")
$extreme->stp_i_priority(): Returns the port number of the port that offers the lowest cost path to the root bridge.
("extremeStpDomainBridgePriority")

Spanning Tree Protocol Port Table

$extreme->stp_p_id(): ("extremeStpPortPortIfIndex")
$extreme->stp_p_stg_id(): ("extremeStpDomainStpdInstance")
$extreme->stp_p_priority(): ("extremeStpPortPortPriority")
$extreme->stp_p_state(): ("extremeStpPortPortState")
$extreme->stp_p_cost(): ("extremeStpPortPathCost")
$extreme->stp_p_root(): ("extremeStpPortDesignatedRoot")
$extreme->stp_p_bridge(): ("extremeStpPortDesignatedBridge")
$extreme->stp_p_port(): ("extremeStpPortDesignatedPort")

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".
