Release Notes for Cisco ONS 15454 SDH Release 4.1.3

OL-4984-01

Caveats

Single-card EtherSwitch

Each E100/E1000 card can be configured as a single-card EtherSwitch configuration to allow VC4-4c

of bandwidth to be dropped at each card. The following scenarios for provisioning are available:

VC4-4c

VC4-2c, VC4-2c

VC4-2c, VC4, VC4

VC4, VC4, VC4, VC4

When configuring scenario 3, the VC4-2c must be provisioned before either of the VC4 circuits.

Multicard EtherSwitch

When deleting and recreating Ethernet circuits that have different sizes, you must delete all VC4 circuits

provisioned to the EtherSwitch before you create the new circuit scenario. (See the preceding

“Single-card EtherSwitch” section on page 6 for details on the proper order of circuit creation.) Enable

front ports so that the VLANs for the ports are carried by the largest circuit first. A safe approach is to

enable the front port before you create any circuits and then retain the front port VLAN assignment

afterwards. If you break the rules when creating a circuit, or if you have to delete circuits and recreate

them again, delete all circuits and start over with the largest first.

ML-Series

DDTS # CSCeb56287

When an ML-series circuit's state is provisioned from In-Service (IS) to Out-of-Service (OOS), and then

back to IS, data traffic does not recover. To avoid this issue, prior to changing the state from IS, set the

POS port to shut down on the CLI. After the state is changed back to IS from OOS, set the POS port to

“no shutdown.” This issue will be resolved in Release 4.6.

DDTS # CSCeb25778

When a MAC-SA is seen for the first time, it is learned, but may age out in less than 5 minutes. If the

same MAC-SA is seen again before the first ages out, the entry will age out after 5 minutes, as expected.

This issue will not be resolved.

DDTS # CSCeb11930

The POS shutdown command will raise PLM-P on the far end for a VC3 circuit in an SDH node. This

occurs on all ML-series cards in nodes running Release 4.0 or 4.1. This issue will be resolved in Release

4.6.

DDTS # CSCin43669

Timer expiration can cause a system crash when you attempt to remove 250 Shared Packet Ring (SPR)

subinterfaces using the “no int spr1” command, while Cisco Discovery Protocol (CDP) is also enabled.

To avoid this issue, either turn off CDP, issue the command, and then turn CDP back on; or remove the

SPR subinterfaces explicitly. This issue will not be resolved.
