Link Ports These are the ports that are used for connection to another device and are used as part of one or
more Network VLANs including the current VLAN. On the display, these will be identified with the
capital letter L. A Link Port cannot be changed from the VLAN Configuration screen. It must be
changed on both ends of the link using the Create Vlan, Extend Vlan, or Delete Link applications.
However, a Link Port can be changed in the VLAN Interface Configuration application, which is a
similar application that is launched on VLAN interfaces either from a VLAN Map or a VLAN Interface
row in one of the Inventory tables. In this application, Link Ports can be toggled from L (not part of
the VLAN) to lu (linked untagged), to lt (linked tagged). This is useful for repairing VLAN entries that
have become inconsistent with the entry for the device at the other end of the link
Rapier
Specific Vlan
Parameters
These apply only to VLANs on Rapier-type devices, and are divided into two areas:
1. Device Wide Parameters - These are read -only and display device-level attributes as Enabled or
Disabled:
- IGMP Status
- IP Multicast Hardware Switching
- OSPF Status
- PIM Status
2. VLAN Interface Parameters - These are read-write and apply only to the selected VLAN:
- IGMP Enabled
- OSPF Area - Set the Open Shortest Path First Area
- OSPF Metric - Set the Open Shortest Path First Metric
- PIM Mode
iMAP Specific
Parameters
These apply only to iMAP devices, and are divided into two areas:
1. Device Wide Parameters - These are read -only and display device-level attributes as Enabled or
Disabled:
- Access Interface - This is the IP interface the device is using to communicate with the NMS.
Options are MGMT (for the Ethernet interface that transports only management data packets) or
the IP address of inband interface (in-band Ethernet interface that interleaves user data packets with
management data packets on the uplink, using a VLAN interface).
- IGMP - Whether IGMP has been Enabled or Disabled for the device. This attribute is displayed as a
device-wide parameter for devices running iMAP software up through release 16.x.x.
2. VLAN Interface Parameters - These are read-only and apply only to the selected VLAN:
- Double Tagged (HVlan) - If the selected VLAN is an HVLAN (and will therefore be a VLAN used to
switch the traffic across the network), this is shown as TRUE. Refer to Section 6.
- Translation Ports - When the VLAN chosen is a translation VLAN (where a service provider takes
a customer VID and translates it into a unique VLAN ID for transport across the network), this field
contains the ports the translation VLAN ID resides on. Refer to Section 6. Note that HVlan and
Translation are mutually exclusive features.
- Forwarding Mode - Displays the current state of VLAN forwarding. You can change it to Standard
or Upstream for the selected VLAN.
- IGMP Snooping - Displays the current state of IGMP Snooping. You can enable or disable IGMP
Snooping for the selected VLAN.
Create Create a new VLAN. A Create New VLAN form will appear, with the default name and number one
that has not been used yet.
Delete Allows the user to delete the selected VLAN. (Note that since the default VLAN [VID 1] cannot be
deleted, this button is inactive when the selected VLAN is VLAN 1.)
