Feature Mismatching

Multiple VSI Partitions

Support for up to two partitions requires BPX switch software 9.2.3 and Firmware Ez. The card uses a
flag in the capability message to report multiple partition capability. Firmware releases that do not
support multiple partitions set this flag to OFF. The multiple partitions capability is treated as a card
attribute and added to the attribute list.
Use of a partition with ID higher than 1 requires support for multiple VSI partitions in both switch
software and BXM firmware, even if this is the only partition active on a the card.
In a y-red pair configuration, the multiple partition capability will be determined by the minimum of
the two cards. A card with no multiple partition capabilities will mismatch if any of the interfaces has
an active partition with ID higher than 1. Attempts to enable a partition with ID higher than 1 in a logical
card that does not support multiple partitions will be blocked.
Table A-4
Configurations
Replacing the current active card with a card with more channels: card will not
mismatch, although the additional channels are NOT available to the user.
Replacing the current active card with a card with fewer channels: the inserted
card will mismatch.
Active or standby Y-cable configuration with both the primary and secondary
card supporting the same number of channels as defined in the logical database:
no mismatch.
Active Y-cable configuration with the Secondary Card supporting fewer
channels than defined in the logical card (primary card) database: the secondary
card will mismatch.
Active Y-cable configuration with the primary card supporting less channels
than the logical card database: the primary card will mismatch.
Active Y-cable configuration with the primary or secondary cards (or both)
supporting more channels then the logical card DB: neither card will mismatch
although the additional channels are NOT available to the user.
Standby Y-cable configuration with the primary or secondary cards supporting
different number of channels: card will mismatch.

Functional Description of Feature Mismatch Checking

The following sections describe 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, this verification is performed:

Mismatch Conditions if Number of Channels Changes
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.
