Ethernet Management Ports and Redundant 
Management Processor Modules
If redundant MPXs both have Ethernet management ports (EMPs), both EMPs in the switch will 
have the same IP address if automatic file synchronization is enabled. If both EMPs are 
plugged into the same subnet, the UI will show that there are duplicate IP addresses on the 
network.
To get around this duplicate 
IP address problem, you must disable automatic file synchroniza-
tion and then you must configure different IP addresses for the two EMPs. To do this, perform 
the following steps:
1. On the primary management module, enter
syncctl
at the system prompt. (See Setting Automatic Config Synchronization on page 6-15 for 
more information on the syncctl command.)
2. If automatic file synchronization is already disabled, simply press 
<Enter>. If it is enabled, 
enter disable at the prompt.
3. Enter
ethernetc
at the prompt. (See Configuring the Ethernet Management Port on page 6-5 for more 
information on the ethernetc command.)
4. Enter 
2= followed by the IP address for the EMP on the primary management module.
5. Enter
save
at the prompt to save the IP address.
6. Enter
renounce
at the prompt to make the primary management module the secondary module and the 
secondary module primary.
7. Log into the now primary management module.
8. On the now primary management module, enter
syncctl
at the system prompt.
9. If automatic file synchronization is already disabled, simply press 
<Enter>. If it is enabled, 
enter disable at the prompt.
10. Enter
ethernetc
at the prompt.
11. Enter 
2= followed by the IP address for the EMP on the management module.
