7600使用笔记

 

show bootvar EHSA standby 模式提供以下特性：
+自动启动，且在active和冗余超级引擎之间bootvar同步。
+在超级引擎的active和冗余状态检测和决定硬件信号。
+每60秒从active往冗余超级引擎进行时钟同步。
+一个冗余超级引擎是启动的，但是不是所有子系统都up，如果
active的超级引擎挂了，冗余超级引擎变成全可操作。
+一个可操作的 超级引擎表现为取代失效单元变为冗余超级引擎。

配置和现实RPR+ ：
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)# redundancy
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

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
Router#
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)#

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-X6248-TEL
?#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

当配置了jumbo frame支持，这些模块丢弃大于8092字节的frame。
啥是：Jumbo Frame?
jumbo frame是大于默认以太frame的frame。（微软拼音里没有"巾贞"这个字?日！）
你通过配置比默认mtu大的size,开启了jumbo frame支持,这是基于每接口的,且,得是
最低是Release 12.1(13)E的IOS,在全局局域网口的mtu大小.
jumbo frame在MSFC的软件中支持分段被路由流量.
jumbo frame支持不分段桥接流量.
配置:
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
?#160;WS-X6148-GE-TX
?#160;WS-X6148V-GE-TX
