Products
S-Series, firmware 7.72.01.0021 and lower
Matrix N-Series DFE, firmware 7.11.01.0025 through 7.62.04.0002
K-Series, firmware 7.72.01.0021 and lower

Changes
Disabled CiscoDP awareness ('
code:
set ciscodp status disable
'), with the goal of transparently forwarding CiscoDP and VTP traffic - both types use the same
code:
01-00-1
[code]x-xx-xx-xx[/code] MAC address structure - through the switch.

Symptoms
CiscoDP and VTP are never flooded through the switch.

Solution/Workaround
For the S-Series and K-Series, upgrade to firmware 7.72.02.0004 or higher.
Release notes state, in the '
code:
Cisco DP Problems Corrected in 7.72.02.0004
' section:
code:
Cisco VTP protocol packets, which use the same MAC address as CiscoDP, are not flooded through the switch.

After upgrade, then globally disable CiscoDP ('
code:
set ciscodp status disable
').

For the N-Series, upgrade to firmware 7.62.06.0004 or higher.
After upgrade, then globally disable CiscoDP ('
code:
set ciscodp status disable
').
