Two Cisco 7609S, everything is ok but a mac conflict with the two
management ports of the
NAM WS-SVC-NAM-2-250 in slot 4, they are on the same Layer 2 subnet, the
problem is only with the
two NAM management port, I have restored to factory default de NAM IP
configuration but in some
way the they preserve the same mac address on the management ports and as a
result I have network
connectivity issues with the NAM, the question is if exists any procedure
to reset the mac address in the NAM,
or this mac is saved in the RSP720 supervisor, if is the case how two
different equipment can have the same mac
address, to increase the problem the mac is not in the NAM Mac range on
7609 range. Is there any way of resetting
this???

I will appreciate your help.
Best regards, Aliet
