关于4507R-E上面使用 Supervisor Engine 6-10GE引擎，在使用10GE接口转换GE接口时，需要注意的几点，给需要的朋友做为参考，祝诸位兄弟实施顺利，同时最后对使用双引擎冗余时，仅可以使用一对GigabitEthernet接口的疑惑，还需要诸位牛人予以帮助。

引擎启动后
查看该模块接口，Gi口为inactive，Te口为notconnect

开机会日志信息，提示未读取到seeprom，如果使用转换模块，需配置GigabitEthernet port group：
000058: *Apr 25 03:53:36.975 UTC: %C4K_GLMMAN-3-X2PLUGGABLESEEPROMREADFAILED: Failed to read seeprom on port Te3/1. Reinsert X2 module or configure GigabitEthernet port group if TwinGigConverter is installed.


官方错误解释：
Error Message    C4K_GLMMAN-3-X2PLUGGABLESEEPROMREADFAILED: Failed to read seeprom on
port [char]. Reinsert X2 module or configure GigabitEthernet port group if
TwinGigConverter is installed.

Explanation    A pluggable has been detected in the TenGig port referred to in the message, but the read of its serial eeprom failed. It could be that the X2 is not seated correctly. A SEEPROM read can also fail if the interface is in 10G mode and a TwinGig Converter is inserted.

Recommended Action    If a TwinGig Converter is inserted, remove the TwinGig Converter or reconfigure the port using the hw-module module <m> port-group <p> select gigabitethernet command. If an X2 is inserted, try removing and re-inserting the X2. If this message still appears, try the X2 in another port. If the X2 fails in another port, call TAC for further troubleshooting. If the X2 succeeds in other ports, the original port may be bad.


开启使用Gigabitethernet命令：
HeilanHome-C4507RE(config)#hw-module module 3 port-group 2 select gigabitethernet
或
用(config)#hw-module uplink select ×××××
    #redundancy reload shelf   
   
日志提示：
000091: *Apr 25 04:00:25.575 UTC: Port Te3/2: TwinGig Converter inserted: vendor: CISCO SYSTEMS, p/n: 800-27645-02, s/n: FDO12310BSY

疑惑：
端口激活后，每个引擎，但仅可使用前两个Gigabitethernet，后两个始终未inactive状态。
经过查找Cisco 文档有如下解释：
When two Supervisor Engine 6-Es are present in a Catalyst 4507R, Catalyst 4507R-E, Catalyst 4510R or Catalyst 4510R-E switch, one X2 uplink is active on both the primary (active) and secondary (standby) supervisor engines by default, or two uplinks will be active in a nonredundant configuration.

Cisco KB 有一个Case是这样解释：
Also, when active and redundant Supervisor Engines are installed in the same chassis, out of eight ports only the four uplink ports (Gig1/1, Gig2/1, Gig 1/2, and Gig2/2) are available. For example, two Gigabit Ethernet ports of the active Supervisor (1/1 and 1/2) and two of the standby (2/1 and 2/2).

这个写的很好的啊，
