Cisco BPX 8600 Series Installation and Configuration
Release 9.3.30, Part Number 78-12907-01 Rev. E0, May 2005
Appendix A Upgrade Information
Upgrade Protection from Release 9.3 to a Later Release
Upgrade Protection from Release 9.3 to a Later Release
Release 9.3 includes an Upgrade Protection feature. This section provides guidelines on upgrades from
BPX switch software Release 9.3 to later releases.
Active statistics collection interferes with the software upgrade process. Prior to Release 9.3, you were
responsible for turning statistics off before beginning the software upgrade procedure.
Standalone
BXM, manual Legacy BXM card is
non-Y-red and the “auto
BXM upgrade”
parameter is set to “N”
for the
cnfnodeparm
command.
1. Use an empty slot to configure the BXM-E card for the desired level of
channel statistics and number of connections. The channel statistics level
and number of connections must be either equal to or higher than the ones
configured on the legacy BXM card that it is replacing. While this step is
optional, if skipped, the BXM-E card may not have the desired channel
statistics level and appropriate number of connections.
2.
Remove the BXM card and replace it with the BXM-E card. If step 1 is
skipped, the BXM-E card can create a mismatch if it does not have the
desired configuration. In that case, use the command
cnfcdparm
<BXM-E slot_num> to set the card to the desired level of channel statistics
and number of connections. This may prolong service disruption.
3. Issue the upgdlogcd <log_card_num> command to upgrade the logical card
database. Switch software upgrades the logical database from the number of
connections configured on the legacy BXM card to the number of
connections configured in step 1. From this point on, mismatch is declared
if the legacy card is reinserted.
Note
In non-Y-red cases, the traffic disruption is unavoidable because the
legacy BXM has to be removed and replaced with the BXM-E card.
Standalone
BXM,
automatic Legacy BXM card is
non-Y-red and the “auto
BXM upgrade”
parameter is set to ‘Y’
for the
cnfnodeparm
command.
1. Use an empty slot to configure the BXM-E card for the desired level of
channel statistics and number of connections. The channel statistics level
and number of connections must be either equal to or higher than the ones
configured on the legacy BXM card that it is replacing. While this step is
optional, if skipped, the BXM-E card may not have the desired channel
statistics level and appropriate number of connections.
2.
Remove the BXM card and replace it with the BXM-E card. If step 1 is
skipped, the BXM-E card can create a mismatch if it does not have the
desired configuration. In that case, use the command
cnfcdparm
<BXM-E slot_num> to set the card to the desired level of channel statistics
and number of connections. This may prolong service disruption.
3.
Switch software automatically upgrades the logical database when step 2 is
done.
Note
In non-Y-red cases, the traffic disruption is unavoidable because the
legacy BXM has to be removed and replaced with the BXM-E card.
