Chapter 5 Configuring the Management Interface and Security
Configuring Management Interface Redundancy
Options
The following options are available:
•
slot-number/interface-number
— The interface number (0/1 or 0/2) of the management port that
is specified as the active port.
Step 1
From the SCE# prompt, type
Interface Mng {0/1 | 0/2} active-port
and press
Enter
.
Specify the desired MNG interface.
Specifying the Active Management Port: Example
The following example shows how to use this command to configure Mng port 2 as the currently active
management port.
SCE# Interface Mng 0/2 active-port

About Management Port Redundancy
The SCE platform contains two RJ-45 management ports. The two management ports provide the
possibility for a redundant management interface, thus ensuring management access to the SCE platform
even if there is a failure in one of the management links. If a failure is detected in the active management
link, the standby port automatically becomes the new active management port.
Note that both ports must be connected to the management console via a switch. In this way, the IP
address of the MNG port is always the same, regardless of which physical port is currently active.
Important information:
•
Only one port is active at any time.
•
The same virtual IP address and MAC address are assigned to both ports.
•
Default:
–
Port 1 = active
–
Port 2 = standby
•
The standby port sends no packets to the network and packets from the network are discarded.
•
When a problem in the active port is encountered, the standby port automatically becomes the new
active port.
•
Link problem, with switch to standby MNG port, is declared after the link is down for 300 msec.
•
Service does not revert to the default active port if/when that link recovers. The currently active
MNG port remains active until link failure causes a switch to the other MNG port.
