Cisco Cisco ONS 15454 M12 Multiservice Transport Platform (MSTP) Notas de publicación

Cisco ONS platforms ship with a Java Runtime Environment (JRE) from Sun Microsystems. 
Occasionally Sun releases maintenance releases to the JRE. The Sun Microsystems website lists JRE 
maintenance releases and the issues resolved for each. Cisco recommends that you review these listings 
to determine if the issues resolved in any given JRE maintenance release warrant a JRE upgrade for your 
particular network. Cisco tests only with the specific JRE actually shipped with the ONS software CD.

In the Network View, a Terminal site for which only the boards but not the connections between them 
are provisioned is displayed as “unknown site.” In the provisioning panel the type shown is Terminal, 
but it is not possible to insert Power values. To correct this, create the connections between the boards. 
This issue will be resolved in a future release.

At the end of a software reset sequence, both the OPT-PRE and OPT-BST cards override the OSRI 
command. The resulting effect is that if an amplifier is switched off by OSRI command and then is 
affected by a software reset command, it switches on the power output at the power set value. Avoid 
inspecting the amplifier optical connectors via a microscope tool when the unit is powered on or there 
is an optical signal connected to its input port (COM RX port). This issue will be resolved in a future 
release.

CTC is unable to communicate with an ONS 15454 that is connected via an Ethernet craft port. CTC 
does, however, communicate over an SDCC link with an ONS 15454 that is Ethernet connected, yielding 
a slow connection. This situation occurs when multiple ONS 15454s are on a single Ethernet segment 
and the nodes have different values for any of the following features: 

Enable OSPF on the LAN

Enable Firewall

Craft Access Only

When any of these features are enabled, the proxy ARP service on the node is also disabled. The ONS 
15454 proxy ARP service assumes that all nodes are participating in the service.

This situation can also occur immediately after the aforementioned features are enabled.  Other hosts on 
the Ethernet segment (for example, the subnet router) may retain incorrect ARP settings for the ONS 
15454s.  

To avoid this issue, all nodes on the same Ethernet segment must have the same values for Enable OSPF 
on the LAN, Enable Firewall, and Craft Access Only. If any of these values have changed recently, it 
may be necessary to allow connected hosts (such as the subnet router) to expire their ARP entries.

You can avoid waiting for the ARP entries to expire on their own by removing the SDCC links from the 
affected ONS 15454 nodes.  This will disconnect them for the purposes of the proxy ARP service and 
the nodes should become directly accessible over the Ethernet. Network settings on the nodes can then 
be provisioned as desired, after which the SDCC can be restored.

This issue will not be resolved.
