“k9w7胖; k9w8瘦(全功能),rcvk9w8瘦(仅仅CAPWAP功能,无无线射频功能)LAP注册WLC后会从WLC 下载对应版本的OS.所以胖AP转瘦AP选择rcvk9w8和k9w8都可以。升级方法可以使用#archive命令或mode键升级”
Introduction
All Cisco Aironet 802.11a/b/g/n and 11ac
Wave 1 wireless access points and bridges currently being shipped run IOS,
except for the OEAP602. (The 1850 and subsequent 11ac Wave 2
wireless access points run Cheetah.)
Note: Some older Cisco access points did
not run IOS, such as the Aironet 340 which ran only VxWorks, and the 1000
series lightweight APs.
Access Point IOS is distributed as a tar
file. These tar files can be downloaded from cisco.com
SDS; lightweight IOS images (k9w8) are also bundled in the WLC software
images (.aes.)
The IOS image names include the
following components:
platform-featureset-tar.version.tar
·
platform- the access point hardware model or family supported by
the image
o
ap1g1 - 700 series (702w beginning with 15.2(4)JB5)
o
ap1g2 - 1600 series
o
ap1g3 - 1530 series, AP803 embedded in IR829 router
o
ap1g4 - 1850 (Cheetah not IOS)
o
ap3g2 - 3700/3600/2700/2600/1700 series
o
ap3g1 - 3500/1260 series
o
ap802 - AP embedded in 819, 812, 886VA-W/887VA-W, and C88x
routers
o
ap801 - AP embedded in 861W, 891W, 1911W routers and most 88xW
routers
o
apw5100 - Rockwell Stratix 5100 WAPAK9, WAPCK9, WAPEK9, WAPZK9
o
c1570 - 1570 series outdoor APs
o
c1520 - 1550 and 1520 series mesh APs
o
c1410 - BR1410
o
c1310 - BR1310
o
c1250 - 1250 series APs
o
c1240 - 1240 series APs
o
c1200 - 1200 series (1200/1210/1220/1230)
o
c1140 - 1140 and 1040 series APs
o
c1130 - 1130 series APs
o
c1100 - 1100 series APs (i.e. the AP1121)
o
c520 - 521 AP
o
c350 - 350 series APs
·
featureset- the set of software features supported by the image -
one of:
o
k9w7 - autonomous (or "site survey") IOS
o
k9w8 - full lightweight IOS (this is what is bundled in
the WLC .aes image, and is factory installed on "mesh" APs)
o
rcvk9w8 - lightweight recovery image - this is
factory installed on lightweight APs, unless a "mesh" image is
specified; it lacks radio firmware
o
boot - bootloader image (not IOS) - normally installed
by manufacturing and not updated in the field
·
version- the IOS
version
o
There is a 1:1 mapping between the lightweight IOS
software version (such as 12.4(23c)JA) and the CUWN version (such as
7.0.98.0)
§
see the Wireless
Solutions Software Compatibility Matrix on CCO
Example:
c1240-k9w7-tar.124-25d.JA1.tar
·
Platform: c1240: 1240 series AP
·
Featureset: k9w7: autonomous IOS
·
Version: 124-25d.JA1: 12.4(25d)JA1
As AP IOS is
always distributed as a tar file, the AP cannot directly execute such a file
(thus, if you were to copy c1240-k9w7-tar.124-25d.JA1.tar directly onto AP
flash, and then try to boot it, this could not work[F1] .) The tar file contains, in
addition to the IOS image proper, the radio firmware files, the HTML GUI files
(if present), and various other files.
The AP IOS tar file must be unbundled into AP flash[F2] using the archive exec command (this is
done in an automated fashion when a lightweight AP is upgraded after joining a
WLC.)
Example:
AP1260#archive download-sw /overwrite
tftp://10.95.42.136/ap3g1-k9w7-tar.124-25d.JA1
After unbundling, the IOS image itself
be in a file called flash:/platform-featureset-mx.version/platform-featureset-mx.version
- for example, flash:/c1240-k9w7-mx.124-25d.JA1/c1240-k9w7-mx.124-25d.JA1.
The AP is configured to boot this image if the bootloader BOOT environmental
variable is set accordingly.
To see what IOS image the AP is
configured to boot, examine the BOOT variable.
Example:
AP3502i#more flash:/env_vars | include
BOOT
BOOT=flash:/ap3g1-k9w8-mx.152-2.JA/ap3g1-k9w8-mx.152-2.JA
To change the BOOT variable, use the IOS
config mode boot
system command.
Example:
AP3502i(config)#boot system flash:/ap3g1-k9w8-mx.124-25e.JA2/ap3g1-k9w8-mx.124-25e.JA2
[F1]因为AP的IOS文件内包含无线射频文件、HTML文件等多种文件,并不是简单复制到Flash即可的;
