Router> enable
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# redundancy
Router(config-red)# mode rpr-plus
Router(config-red)# ^Z
Router# show redundancy states
重新启动默认的自动同步：
Router(config)# redundancy
Router(config-red)# main-cpu
Router(config-r-mc)# auto-sync standard
Router(config-r-mc)# auto-sync bootvar
Router(config-r-mc)# end
Router# copy running-config startup-config
关闭自动同步，只打开配置active超级引擎寄存器的自动同步
Router(config-red)# main-cpu
Router(config-r-mc)# no auto-sync standard
Router(config-r-mc)# auto-sync config-register
Router(config-r-mc)# end
Router# copy running-config startup-config
Router(config)# redundancy 显示冗余状态：
Router# show redundancy states
This example 如何perform FSU:
Router# config terminal
Router(config)# config-register 0x2
Router(config)# boot system flash slot0: c6sup22-jsv-mz.121-11.E
Router# copy running-config start-config
Router# hw-module reset
Router# redundancy force-switchover

查看硬件信息
Router# show hardware
7600能用interface range命令，(y!e!a!h!)
Router(config-if)# interface range fastethernet 5/1 - 5, gigabitethernet 1/1 - 2
Router(config-if)# no shutdown
Router(config-if)#

以下交换模块支持做到入口frame最大到8092字节：
#160;WS-X6516-GE-TX when operating at 100 Mbps
#160;WS-X6148-RJ-45 and WS-X6148-RJ-45V
#160;WS-X6148-RJ21 and WS-X6148-RJ21V
#160;WS-X6248-RJ-45

#160;WS-X6248A-RJ-45
#160;WS-X6248A-TEL
#160;WS-X6348-RJ-45 and WS-X6348-RJ45V
#160;WS-X6348-RJ-21 and WX-X6348-RJ21V
Router# configure terminal
Router(config)# interface gigabitethernet 1/2
Router(config-if)# mtu 9216
Router(config-if)# end
Router(config)# system jumbomtu mtu_size
When configuring the MTU size, note the following syntax information:
•For VLAN interfaces and Layer 3 Ethernet ports, supported MTU values are from 64 to 9216 bytes.
•For Layer 2 Ethernet ports with Release 12.1(13)E and later releases, you can configure only the global egress LAN port MTU size (see the "Configuring the
Global LAN Port MTU Size" section).
•For Layer 2 Ethernet ports with earlier releases, the only supported MTU size is 9216 bytes.
配置二层以太接口: 以下交换模块不支持isl封装:
The following switching modules do not support ISL encapsulation:
#160;WS-X6501-10GEX4
#160;WS-X6502-10GE
#160;WS-X6548-GE-TX
#160;WS-X6548V-GE-TX
