Cisco Cisco ONS 15305 Multiservice Customer Access Platform Notas de publicación

Upgrading nodes, that have active DCC links, from R.1.x to R.2.0.5, may require reconfiguration of the 
DCC mode locally. Refer DDTS#CSCEG11010.

Spanning Tree Protocol (STP) for each VLAN is no longer a feature supported for ONS 15305. From 
R.2.x onwards, STP for each VLAN is removed and attributes are no longer available as management 
solutions. The implementation in R.1.x was according to an early draft of IEEE 802.1 and 
interoperability with third party vendors could not be guaranteed successful. An additional reason for 
this feature removal is the introduction of Rapid Spanning Tree Protocol (RSTP). An upgrade from R.1.x 
to R.2.x will turn off the STP for each VLAN algorithm, even though it is set in the CDB file.

Reconfigure all DCC channels configured with mode set to IpOverDcc and IpEncapsulation set to 
proprietary (

).

For all DCC channels on the system where mode is set to IpOverDcc and IpEncapsulation is set to 
proprietary, the IpEncapsulation needs to be reconfigured before upgrading from R.1.x to R.2.0.5.

If the DCC IpEncapsulation is not reconfigured before upgrading to R.2.0.5, loss of connectivity over 
the DCC channels might occur.

For all DCC channels on the system where mode is set to notUsed, remModule, osi, or transparent, 
reconfiguration of IpEncapsulation is not required and must be skipped. For all DCC channels on the 
system where IpEncapsulation is set to ppp, this step is not required and must be skipped.

To change the default setting for DCC IpEncapsulation:

Set IpEncapsulation to ppp. 

Set IpEncapsulation back to proprietary.

Save this configuration.

Upgrade software to R2.0 as described in
