Feature Mismatching
Functional Description of Feature Mismatch Checking
This section describes some of the behavior related to feature mismatching in this release.
Card Insertion/Mismatch Checking
The BXM and UXM card insertion/mismatch checking verifies that the inserted card supports all
features currently available to the user. For feature mismatching, the following verification methods are
performed:
•
When a single card is inserted, if the physical card does not support the specific feature, and the
feature has been enabled, the card will mismatch.
• When a single card is inserted, if the feature is not enabled, and the physical card supports the new
feature, the logical card database should be updated to reflect this feature.
•
During Y-cable mismatch, if the feature is enabled and if the inserted primary or secondary card does
not support this feature, the card will mismatch.
• During Y-cable mismatch, if the feature is not enabled and if the inserted primary or secondary card
does not support the feature, the logical card database is updated to reflect this.
•
During Y-cable mismatch, if the feature is disabled, and if both the inserted primary and secondary
cards both support this feature, the logical database is updated to reflect this.
UI Commands and Enabling Feature Mismatch
When a feature is enabled, a verification is made to assure that the hardware and firmware supports this
feature. That is, during feature configuration, switch software performs a check to determine if the
feature is supported by the BXM or UXM card. For example, if you are trying to add APS on a specific
line (with
addapsln ) and the BXM card does not support this feature, a warning message is displayed
and the addition is not completed.
The dspcd command gives you mismatch information for the specified card.
If the feature is not available, a warning message is displayed and the feature will not be enabled.
addyred/delyred Mismatch Checking
During the addyred command mismatch checking, the following verifications are done:
•
A verification to ensure that both the primary and secondary cards support the activated features.
For example, if on the primary card, the APS feature has been configured, and on the secondary card
this feature is not available, you are blocked from using the
addyred command.
• If the feature is not enabled, and the secondary card does not support similar feature sets, switch
software updates its logical database to reflect this.
•
Following a delyred command execution, the logical card’s database is updated to reflect the
primary card’s capabilities.
The addyred commands ( addyred, delyred, dspyred, prtyred, switchyred ) will verify feature support
on both the primary and secondary cards.
