| =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.

| =item $extreme->set_i_vlan ( vlan, ifIndex )
 | |
| 
 | |
| Changes an access (untagged) port VLAN, must be supplied with the numeric
 | |
| VLAN ID and port ifIndex.  This method should only be used on end station
 | |
| (non-trunk) ports.
 | |
| 
 | |
|   Example:
 | |
|   my %if_map = reverse %{$extreme->interfaces()};
 | |
|   $extreme->set_i_vlan('2', $if_map{'FastEthernet0/1'}) 
 | |
|     or die "Couldn't change port VLAN. ",$extreme->error(1);
 | |
| 
 | |
| =item $extreme->set_i_pvid ( pvid, ifIndex )
 | |
| 
 | |
| Sets port default VLAN, must be supplied with the numeric VLAN ID and
 | |
| port ifIndex.  This method should only be used on trunk ports.
 | |
| 
 | |
|   Example:
 | |
|   my %if_map = reverse %{$extreme->interfaces()};
 | |
|   $extreme->set_i_pvid('2', $if_map{'FastEthernet0/1'}) 
 | |
|     or die "Couldn't change port default VLAN. ",$extreme->error(1);
 | |
| 
 | |
| =item $extreme->set_add_i_vlan_tagged ( vlan, ifIndex )
 | |
| 
 | |
| Adds the VLAN to the enabled VLANs list of the port, must be supplied with the
 | |
| numeric VLAN ID and port ifIndex.
 | |
| 
 | |
|   Example:
 | |
|   my %if_map = reverse %{$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 $extreme->set_remove_i_vlan_tagged ( vlan, ifIndex )
 | |
| 
 | |
| Removes the VLAN from the enabled VLANs list of the port, must be supplied
 | |
| with the numeric VLAN ID and port ifIndex.
 | |
| 
 | |
|   Example:
 | |
|   my %if_map = reverse %{$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);
