A mixin class for vlan related infos from the CISCO-VTP-MIB for 802.1Q-trunks and CISCO-VLAN-MEMBERSHIP-MIB for access ports. The mixin-module provides methods for mapping between vlan-ids and vlan-names und relations between interfaces and vlan-ids, tagged or untagged on these ports.
Returns a hash reference with vlan-ids as keys and the corresponding vlan-names as values:
{ vlan_id => vlan_name, vlan_id => vlan_name, ... , }
Returns a hash reference with the vlan-ids as keys and tagged and untagged if_idx as values:
{ vlan_id => { tagged => [if_idx, ..., ], untagged => [if_idx, ..., ], }, ... , }
Returns a hash reference with the interfaces as keys and tagged and untagged vlan-ids as values:
{ if_idx => { tagged => [vlan_id, ..., ], untagged => [vlan_id, ..., ], }, ... , }
Fetch basic Vlan related SNMP values from the host. Don't call this method direct!
Only for developers or maintainers.
Fetch selected rows from vtpVlanTable during object initialization.
The callback for _fetch_vtp_vlan_tbl_entries.
Fetch selected rows from vlanTrunkPortTable during object initialization.
The callback for _fetch_vtp_vlan_trunk_port_tbl_entries.
Fetch selected rows from vmMembershipTable during object initialization. The table maybe empty if there is no switch port in access mode.
The callback for _fetch_vm_membership_tbl_entries.
