Logging Into the Switch Setting the EMP Port’s IP Address
OmniSwitch AOS Release 8 Switch Management Guide May 2014 page 1-9
Setting the EMP Port’s IP Address
In order to access the switch through the EMP port the port's default IP and network mask should be
changed. There are multiple IP addresses to consider when configuring the EMP port.
• The EMP IP address of the switch stored in the vcboot.cfg file (EMP-CHAS1).
• The EMP IP address of the switch stored in NVRAM. (EMP-CMMA-CHAS1)
Only the EMP IP address stored in the vcboot.cfg file is required for remote access to the switch. The
NVRAM IP address is designed for chassis-based products with multiple CMMs and is not required for
the OS6860. If multiple EMP IP addresses are configured:
• All the EMP IP addresses must be in the same subnet.
• Each of the EMP IP addresses must be unique.
• The NVRAM IP address will be retained even if the switch configuration is erased.
Modifying the EMP IP Address
Use the ip interface command to modify the EMP IP address as shown below.
-> ip interface emp address 10.255.1.1 mask 255.255.0.0
Changes made using the ip interface command are stored in the vcboot.cfg file.
Modifying the NVRAM EMP IP Address
Must be connected to the associated console port before attempting to change IP address information
using the modify boot parameters command as shown below:
-> modify boot parameters
Boot > boot empipaddr 10.255.1.50
Boot > boot empmasklength 16
Boot > show
EMP IP Address: 10.255.1.50/16
(additional table output not shown)
Boot > commit system
Boot > commit boot
Boot > exit
• If you use the commit system command only, changes will not be saved to the switch's non-volatile
memory and will be lost if the switch is rebooted.
• For additional information on EMP IP addresses on multiple switches configured as a Virtual Chassis
refer to the “Configuring Virtual Chassis EMP IP Addresses” on page 13-21.
