Database Merge Guidelines

When merging two fabrics, follow these guidelines:

Management Interface Configuration
The management interface on the switch allows multiple simultaneous Telnet or SNMP sessions. You
can remotely configure the switch through the management interface (mgmt0), but first you must
configure some IP parameters so that the switch is reachable. You can manually configure the
management interface from the CLI. You can configure the mgmt 0 interface with either IPv4 address
parameters or an IPv6 address.
On director class switches, a single IP address is used to manage the switch. The active supervisor
module's mgmt0 interface uses this IP address. The mgmt0 interface on the standby supervisor module
remains in an inactive state and cannot be accessed until a switchover happens. After a switchover, the
mgmt0 interface on the standby supervisor module becomes active and assumes the same IP address as
the previously active supervisor module.
The management port (mgmt0) is autosensing and operates in full duplex mode at a speed of
10/100/1000 Mbps (1000 Mbps is only available on the Supervisor-2 module). Autosensing supports
both the speed and the duplex mode. On a Supervisor-1 module, the default speed is 100 Mbps and the
default duplex mode is auto. On a Supervisor-2 module, the default speed is auto and the default duplex
mode is auto.
You can set the management interface in the Fabric Manager Preferences screen to use SNMP over TCP.
The advantages of this setting are an increased buffer size and faster transfer rate. If your fabric has a
long timeout period, it may prevent you from using SNMP (which may have a relatively shorter timeout
period). If so, change this setting to false and restart Fabric Manager Server. UDP is used instead.
Before you begin to configure the management interface manually, obtain the switch's IPv4 address and
Note
IPv4 subnet mask or the IPv6 address. Also make sure the console cable is connected to the console port.

Default Gateway Configuration

The supervisor module sends IP packets with unresolved destination IPv4 addresses to the default
gateway (see
Cisco MDS 9000 Family Fabric Manager Configuration Guide

Be aware that the merge is a union of the existing and the received database in each switch in the
fabric.
Do not configure an IP address as a server on one switch and as a peer on another switch. The merge
can fail if this configuration exists.
Verify that the union of the databases does not exceed the maximum limit of 64.
