Enhanced Link Recovery after Link Reflection
• Cisco Number CSCsb51681
SCOS 2.5.8 supports an enhanced link recovery protocol that ensures port recovery after link
reflection.
The link reflection function forces down the reciprocal port when the link fails. When the link
is restored, the reciprocal port that had been forced down is automatically restored, also. The
enhanced link recovery functionality tests the reciprocal port before restoring it. If the port is
down, the enhanced link recovery procedure is applied.
The enhanced link recovery mode is supported for all link failure reflection modes (normal, all
ports, and all ports linecard aware).
By default, this new mode is disabled. To enable the enhanced link recovery mode, use the
following CLI command:
configure
interface linecard 0
link port-enhance-recovery
To disable the enhanced link recovery mode, use the following CLI command:
configure
interface linecard 0
no link port-enhance-recovery
Package ID Variable Not Correctly Updated in Pull Mode
• Cisco Number CSCsc04812
In the following scenario, the subscriber package ID variable may not be correctly updated:
• Package ID is configured via anonymous subscriber templates.
• A new IP address spawns a new anonymous subscriber, which triggers a pull request to
the SM.
• The pull response returned by the SM includes the subscriber state, but no package ID.
• When Control receives a pull response, it updates the state and any variables that were
changed by the pull response. Variables that were not updated by the pull response
retain the default value. In this case, the package ID assigned by the anonymous
subscriber template will NOT be retained.
This issue was identified and fixed in SCOS 2.5.8.
