2. Configure the MD entities first. Up to eight MDs can be configured in a 9145EMP NID,
using the procedures described in section 11.3.
3. Configure the MA and MEG entities. A MA/MEG must be associated with an underlaying
VLAN Multiplexing record, with the exception of untagged MEGs/MAs. Choose the proper
VLAN type (C-Tag or S-Tag) when you create the MAs and MEGs.
If the VLAN type is S, then the VLAN list must contain only one element, which is the S-
Tag value of the corresponding VLAN Multiplexing record.
If the VLAN type is C, the VLAN list must contain only VLAN IDs that are included in C-
VLAN list of the corresponding VLAN Multiplexing record. The list of VLANs associated
with an CType MA or MEG can be changed runtime; however all VLANs must be included
in the C-VLAN list of the VLAN multiplexing record
4. Configure the MEPs. Each MEP is associated with an existing MA or MEG, created in
step 2.
5. Create the MIP entities. A MIP is associated with an MD (for 802.1ag MIPs) or with a
MEG (for Y.1731 MIPs).
6. If required, configure the AIS client server relationships, as described in section 11.9. The
AIS client server relationships are established between the MEPs and MIPs configured in
the previous steps.
At runtime, deleting a lower level entity (such as a MA or a MEG) will automatically delete all
higher level entities and relationships that are attached to the deleted object. For example, delet-
ing an MD will automatically delete the MAs attached to the MD, as well as all MEPs, MIPs, and
AIS associations related to the deleted MD
. VLAN Multiplexing records associated with MAs or
MEGs cannot be deleted while the MA is still configured.
11.1.6 Screen Navigation
SOAM parameters and procedures are configured using the menus described in this chapter.
The menu hierarchy for SOAM is illustrated in Figure 11-3.
To select an item on a screen, type the number of the item and press Enter. The setting will be
highlighted. To toggle between values within that item, use the Space bar.
If there is more than one page, the screen will offer the option of using (F)irst, (P)rev,
(N)ext, and (L)ast to navigate. Press Esc to return to a previous screen.
All screens that show existing objects are refreshed automatically every 5 seconds; items that
are being modified are not refreshed.
In Figure 11-3, some screens (MDs, MAs, MEPs and MIPs) are highlighted with a blue rectangle.
For these entities, actions (display entities, create new entity, edit attributes) are executed in sep-
arate screens.
