如何查看Cisco Sup720的SP與RP的內(nèi)存和FLASH狀態(tài)
首先Cisco 720引擎由SP（Switch Processor）和RP（Route Processor）組成，完整的引擎上會(huì)有3個(gè)
部分：一是最下面那塊大板（引擎），另一個(gè)是右邊的一塊子卡（PFC），最后是左邊的子卡
（MSFC），引擎和PFC合稱交換引擎（SP），MSFC稱路由引擎（RP）。
SP和RP是獨(dú)立的操作系統(tǒng)，所以各自有Flash和Memory。如上圖（圖片來源于Cisco官方文檔），
左邊的Flash和內(nèi)存屬于SP，右邊的Flash和內(nèi)存屬于RP。
另外，Flash有內(nèi)置和外置之分。內(nèi)置的叫bootflash，外置的在Sup1上叫Slot0:，從Sup2開始，Cisco
支持ATA格式的PCMCIA Flash，因此Sup2上會(huì)有Slot0:和Disk0:，如果是MEM格式的用Slot0:，如果
是ATA格式的用Disk0:，到Sup720，開始用CF卡，也就只支持ATA格式了。SP上的所有設(shè)備都會(huì)有個(gè)
sup-的前綴，所以sup-bootflash:就是SP上的Flash，sup-slot0:就是SP上的PCMCIA插槽。而RP上的Flash
則直接是bootflash。
注意：在從CatOS升級(jí)到IOS之后，原先引擎中的bootflash會(huì)被改名為sup-bootflash，而原先MSFC
的bootflash會(huì)被認(rèn)為是升級(jí)后的引擎的bootflash。雖然如此，但6500/7600是不能通過MSFC的bootflash
上的IOS啟動(dòng)的，而必須通過sup-bootflash中的IOS啟動(dòng)。即，運(yùn)行Native IOS時(shí)，IOS文件必須被放置
在sup-bootflash中，才會(huì)啟動(dòng)。放在bootflash是可以的，但無法啟動(dòng)。
如果是運(yùn)行CatOS 加MSFC 的IOS 時(shí)，SP（Swtich processer）作為SUP 引擎的主控系統(tǒng)（運(yùn)行
CatOS），MSFC作為引擎的RP（Router Processer）子卡存在（運(yùn)行IOS），在這種情況下CatOS文件和
IOS文件是相互獨(dú)立的兩個(gè)文件。
但Native IOS文件同時(shí)包含了RP部分和SP部分。所以如果是運(yùn)行Native IOS，那么引擎先從SP引導(dǎo)，
讀取IOS中SP的部分，加載成功后將控制轉(zhuǎn)到RP，進(jìn)行RP部分的引導(dǎo)，但由于RP中的Flash是沒有
IOS的（放在里面也不會(huì)被啟動(dòng)），所以用TFTP的形式從SP下載IOS中的RP部分，引導(dǎo)完后，控制權(quán)
留在RP上，因此在啟動(dòng)完成后的引擎上show version，可以發(fā)現(xiàn)IOS版本與flash中的文件稍有不同，會(huì)
有一個(gè)rp的字樣，這表示的RP部分，而切換到SP的Console后再show version則可以看到sp的字樣。
說明：通過命令remote command switch show version可以直接顯示SP 控制臺(tái)的show version命令。或
者執(zhí)行remote command module x show version（其中x代表引擎的槽位號(hào)）也是一樣的。如果想直接登陸
到SP的控制臺(tái)，可以通過執(zhí)行remote login switch，或者remote login module x（x代表引擎的槽位號(hào)）。
這些命令在升級(jí)SUP2的內(nèi)存和FLASH時(shí)用于確定信息比較有用。
案例：
C7609#dir sup-bootflash:
Directory of sup-bootdisk:/
1 -rw- 83574340 May 28 2007 16:18:10 +08:00 s72033-adventerprisek9_wan-mz.122-18.SXF9.bin
512040960 bytes total (394903552 bytes free)
C7609#dir bootflash:
Directory of bootflash:/
1 -rwx 48420612 May 24 2007 20:23:24 +08:00 s72033-jk9o3sv-mz.122-18.SXD7b.bin
65536000 bytes total (16818096 bytes free)
由上面的顯示結(jié)果可知，sup-bootflash的大小為512MB，bootflash的大小為64MB。即，SP的flash大
小為512MB，RP的flash大小為64MB。

可以看到執(zhí)行remote login switch就可以將控制臺(tái)從RP切換到SP。在SP下執(zhí)行show version與在RP
下直接執(zhí)行remote command switch show version的效果是一樣的。
