Cisco Systems EA6500 Manual De Usuario

The two Gigabit Ethernet interfaces on the redundant supervisor engine are always active.

RPR+ switchover takes place after the failed supervisor engine completes a core dump. A core dump 
can take up to 15 minutes. To get faster switchover time, disable core dump on the supervisor 
engines. 

For redundant operation, the following hardware configuration guidelines and restrictions apply:

Supervisor engine redundancy does not support nondefault VLAN data file names or locations. Do 
not enter the vtp file file_name command on a switch that has a redundant supervisor engine.

Cisco IOS running on the supervisor engine and the MSFC supports redundant configurations where 
the supervisor engines and MSFC routers are identical. If they are not identical, one will boot first 
and become active and hold the other supervisor engine and MSFC in a reset condition.

Each supervisor engine must have the resources to run the switch on its own, which means all 
supervisor engine resources are duplicated. In other words, each supervisor engine has its own Flash 
device and console port connections. 

Make separate console connections to each supervisor engine. Do not connect a Y cable to the 
console ports. 

Both supervisor engines must have the same system image (see the 

If the redundant supervisor engine is running Catalyst operating system software, remove 
the active supervisor engine and boot the switch with only the redundant supervisor engine 
installed. Follow the procedures in the current release notes to convert the redundant 
supervisor engine from Catalyst software.

The configuration register in the startup-config must be set to autoboot (see the 

).

Before installing a redundant supervisor engine, enter the no vtp file command to return to the 
default configuration.

There is no support for booting from the network.
