 | |
| 
 | |
| Use or create in a subclass of SNMP::Info.  Do not use directly.

 | |
| 
 | |
| 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.

| =item $vtp->set_i_vlan ( vlan, ifIndex )
 | |
| 
 | |
| Changes an access (untagged) port VLAN, must be supplied with the numeric
 | |
| VLAN ID and port C<ifIndex>.  This method should only be used on end station
 | |
| (non-trunk) ports.
 | |
| 
 | |
|   Example:
 | |
|   my %if_map = reverse %{$vtp->interfaces()};
 | |
|   $vtp->set_i_vlan('2', $if_map{'FastEthernet0/1'}) 
 | |
|     or die "Couldn't change port VLAN. ",$vtp->error(1);
 | |
| 
 | |
| =item $vtp->set_i_pvid ( pvid, ifIndex )
 | |
| 
 | |
| Sets port default VLAN, must be supplied with the numeric VLAN ID and
 | |
| port C<ifIndex>.  This method should only be used on trunk ports.
 | |
| 
 | |
|   Example:
 | |
|   my %if_map = reverse %{$vtp->interfaces()};
 | |
|   $vtp->set_i_pvid('2', $if_map{'FastEthernet0/1'}) 
 | |
|     or die "Couldn't change port default VLAN. ",$vtp->error(1);
 | |
| 
 | |
| =item $vtp->set_i_untagged ( vlan, ifIndex )
 | |
| 
 | |
| This method attempts to work out whether the port referenced by ifIndex is
 | |
| trunking, and if so will return the value of C<set_i_pvid>. Otherwise, the
 | |
| value of C<set_i_vlan> is returned.
 | |
| 
 | |
| =item $vtp->set_add_i_vlan_tagged ( vlan, ifIndex )
 | |
| 
 | |
| Adds the VLAN to the enabled VLANs list of the port, must be supplied with the
 | |
| numeric VLAN ID and port C<ifIndex>.
 | |
| 
 | |
|   Example:
 | |
|   my %if_map = reverse %{$vtp->interfaces()};
 | |
|   $vtp->set_add_i_vlan_tagged('2', $if_map{'FastEthernet0/1'}) 
 | |
|     or die "Couldn't add port to egress list. ",$vtp->error(1);
 | |
| 
 | |
| =item $vtp->set_remove_i_vlan_tagged ( vlan, ifIndex )
 | |
| 
 | |
| Removes the VLAN from the enabled VLANs list of the port, must be supplied
 | |
| with the numeric VLAN ID and port C<ifIndex>.
 | |
| 
 | |
|   Example:
 | |
|   my %if_map = reverse %{$vtp->interfaces()};
 | |
|   $vtp->set_remove_i_vlan_tagged('2', $if_map{'FastEthernet0/1'}) 
 | |
|     or die "Couldn't add port to egress list. ",$vtp->error(1);
