Release Notes for Cisco ONS 15454 Release 7.0.2
OL-11368-01
Caveats

After setting the node time (either manually or via NTP) you must wait for the endpoint of the interval
to be reached before the end time will reflect the recently-set node time. Until this has occurred, the date
time stamp for the end of the retrieved interval remains 12/31/69. This issue has been closed and will not
be resolved.

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.

Microsoft Windows XP uses more memory than previous Microsoft operating systems, and this may
result in reduced CTC performance. To avoid reduced performance, you can:
• Limit the number of nodes you log into
• Avoid or limit bulk operations
• Avoid bulk circuit deletion
• Prevent CTC’s discovery of DCC connected nodes by using the login “Disable Network Discovery”
feature
• Prevent CTC’s discovery of circuits unless needed by using the login “Disable Circuit Management”

When a node connected via SDCC has no Ethernet LAN connectivity, display of SDCC termination
alarms is delayed if the fiber connecting a DCC connected node is removed. This issue cannot be
resolved.
