4. In the Monitored Radio interface field, select the Monitored Radio Interface. The Controlled Ethernet
Interface, defined above, is disabled upon a failure indication on the Monitored Radio Interface. You can
select a radio or TDM interface, or a radio protection or Multi-Carrier ABC group, as the Monitored Radio
Interface.
5. In the ASP admin field, select Enable to enable Automatic State Propagation on the interface pair, or
Disable to disable Automatic State Propagation on the pair.
6. Optionally, in the ASP trigger by remote fault field, select Enable if you want to configure the system to
disable the Controlled Ethernet Interface upon a radio failure at the remote side of the link from the
Monitored Radio Interface. ASP events will only be propagated to Controlled Interfaces with LLF IDs that
match LLF IDs of affected Controlled Interfaces at the other side of the link.
7. Optionally, in the Auto state propagation CSF mode admin field, select Enable or Disable to enable or
disable Client Signal Failure (CSF) mode. In CSF mode, the ASP mechanism does not physically shut down
the Controlled Interface when ASP is triggered. Instead, the ASP mechanism sends a failure indication
message (a CSF message). The CSF message is used to propagate the failure indication to external
equipment.
8. In the ASP LLF ID field, select an ID for Link Loss Forwarding (LLF). When ASP trigger by remote fault is set to
Enable, ASP events at the other side of the link are propagated to Controlled Interfaces with LLF IDs that
match the LLF IDs of affected Controlled Interfaces at the other side of the link. LLF IDs are unique per
Monitored Interface. That is, if LLF ID 1 has been used for a Controlled Interface that is grouped with fixed
radio interface 1, that ID cannot be used again for another Controlled Interface grouped with fixed radio
interface 1. However, it can be used for Controlled Interface grouped with fixed radio interface 2. You can
select an LLF ID between 1 and 30.
9. this procedure to assign additional Controlled Interfaces to the Monitored Interface, or to set up additional
ASP pair with other interfaces. Controlled Interfaces can only be assigned to one ASP pair. Monitored
Interfaces can be assigned to multiple ASP pairs.
To edit an Automatic State Propagation interface pair:
1. Select the interface pair in the Automatic state propagation configuration table.
2. Click Edit. The Automatic State Propagation – Edit page opens. The Edit page is similar to the Add page
(Figure 202), but the Controlled Ethernet Interface and Monitored Radio Interface parameters are read-
only.
To delete an Automatic State Propagation interface pair:
1. Select the interface pair in the Automatic state propagation configuration table.
2. Click Delete. The interface pair is removed from the Automatic state propagation configuration table.
To delete multiple interface pairs:
1. Select the interface pairs in the Automatic state propagation configuration table or select all the interfaces
by selecting the check box in the top row.
2. Click Delete. The interface pairs are removed from the Automatic state propagation configuration table.
