 | |
| 
 | |
| 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.

 | |
| 
 | |
| Parses C<mac_index>,C<mau_autostat>,C<mau_type_admin> in

| 
 | |
| Returns either (auto,full,half).

| =item $extreme->i_ignore()
 | |
|

| 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) {

| identifier (iid)
 | |
| 
 | |
| Returns (C<ifIndex>) for both key and value since we're using
 | |
| F<EXTREME-FDB-MIB> rather than F<BRIDGE-MIB>.

 | |
| (C<extremePethPortMeasuredPower>)
 | |
| 
 | |
| =item $extreme->peth_power_watts()
 | |

 | |
| 
 | |
| 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:

 | |
| 
 | |
| 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'})

| =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

 | |
| 
 | |
|   Example:
 | |
|   my %if_map = reverse %{$extreme->interfaces()};

|   $extreme->set_add_i_vlan_tagged('2', $if_map{'FastEthernet0/1'})

 | |
| 
 | |
|   Example:
