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.
