CISCO 라우터의 IOS 구분방법
출처는 공성호씨의 nnw에서 가져왔습니다.
보통 cisco ios를 이렇게 나누는 걸로 알고 잇습니다
is - 기본버젼?
ds - 이게 lab구성용으로 좋을듯(ipx/spx가 되네요)
js - 엔터프라이스 급이라고 하네요.
show version 커맨드를 통해 Cisco IOS 에 대한 정보를 살펴보면 대개 다음과 같은 내용의 한 줄을 볼 수가 있는데, 그 형식은 다음과 같습니다.
'platform_series' Software ('image_name'), Version 'version' [,'release_type']
이 가운데 플랫폼의 시리즈 넘버를 가리키는 'platform_series' 는 별다른 설명을 요하는 것 같지 않구요, 'image_name' 과 'version', 그리고 'release_type' 에 대한 설명을 두 세차례에 나누어 올리도록 하겠습니다. 그 첫번째로 오늘은 'image_name', 즉 Cisco IOS Software Image 의 naming convention 에 대해 말씀드리지요.

[ Cisco IOS Software Image Naming Convention ]
[ 1 ] 개 요
일반적으로 image name 은 다음과 같이 세 파트로 이루어져 있습니다.
PPPPP - FFFF - MM
PPPPP : Platform
FFFF : Features
MM : Run-time memory and compression format
한편, 이미지가 올려진 플랫폼이 시스템 보드일 경우 이름 명명 방식이 바뀌어지지만, 그 역시 다음과 같이 세 파트로 이루어져 있습니다.
BBB - PPPP - MM
BBB : Board
PPPP : Platform
MM : Run-time memory and compression format
여기서 마지막의 rum-time memory 는 실행시 이용되는 메모리 영역을 나타냅니다.
그럼 각각의 부분에 들어가는 코드와 그 내용들에 대해 구체적으로 살펴보겠습니다.

[ 3 ] Cisco IOS Software Run-Time Memory Space (MM)
Image name 의 세번째 부분은 대개 두 개의 알파벳 문자로 이루어져 있으며, 앞에 있는 문자는 IOS 이미지가 실행되는 메모리 영역을, 뒤에 있는 문자는 IOS 바이너리 이미지를 압축하는데 사용한 압축 방법을 나타내고 있습니다.
먼저 IOS 이미지가 실행되는 영역에 따라
f : Image runs in Flash memory
m : Image runs in RAM
r : Image runs in ROM
l : Image is relocated at run time
으로 구분되며, IOS 이미지의 압축 방법에 따라
z : Image is Zip compressed (lowercase z)
x : Image is Mzip compressed
w : Image is "Stac" compressed
로 구분됩니다.
[ 4 ] 맺 음 말
이상으로 IOS Software Image 의 naming convention 에 대해 알아보았습니다.
하지만 특정 customer 를 위한 Special Image, 그밖에 일부 Obsolete Image, 그리고 동일한 IOS Image 일지라도 release version 에 따라 약간씩 변화되고 상이하게 명명된 이름들로 인해 획일적인 적용이 무리가 있을 수도 있음을 알려드립니다.

[ 3 ] Cisco IOS Software Run-Time Memory Space (MM)
Image name 의 세번째 부분은 대개 두 개의 알파벳 문자로 이루어져 있으며, 앞에 있는 문자는 IOS 이미지가 실행되는 메모리 영역을, 뒤에 있는 문자는 IOS 바이너리 이미지를 압축하는데 사용한 압축 방법을 나타내고 있습니다.
먼저 IOS 이미지가 실행되는 영역에 따라
f : Image runs in Flash memory
m : Image runs in RAM
r : Image runs in ROM
l : Image is relocated at run time
으로 구분되며, IOS 이미지의 압축 방법에 따라
z : Image is Zip compressed (lowercase z)
x : Image is Mzip compressed
w : Image is "Stac" compressed
로 구분됩니다.
[ 4 ] 맺 음 말
이상으로 IOS Software Image 의 naming convention 에 대해 알아보았습니다.
하지만 특정 customer 를 위한 Special Image, 그밖에 일부 Obsolete Image, 그리고 동일한 IOS Image 일지라도 release version 에 따라 약간씩 변화되고 상이하게 명명된 이름들로 인해 획일적인 적용이 무리가 있을 수도 있음을 알려드립니다.
