=item $vtp->i_vlan()
|

Returns a mapping between ifIndex and assigned VLAN ID for access ports and the

default VLAN ID for trunk ports.

Returns reference to hash of arrays: key = ifIndex, value = array of VLAN IDs.

These are the VLANs which are members of enabled VLAN list for the port.

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