IOS 12.3新命名规范详细图解

Cisco在版本12.3之前,每个特性都需要对IOS进行升级,这样对于客户来说对于各种版本的IOS的选择来说具有很大的困惑。现在思科12.3版本(路由器)或者12.2S版本(交换机)对于众多的特性进行了打包(packaging)策略用于简化选择:44个特性被组合成路由器的八个特性集,多层交换机的七个特性集和两层交换机的两个特性集。根据ITExamPrep.com报道K8特性集从2003年八月开始被K9特性集所取代。

交换机软件包(Switches p ackages)

该特性包主要针对的交换机产品从2900到6500,包括以下特性包: Layer2 Base, LAN Base, IP Base, IP Services, Advanced IP Services, Enterprise Services 和Advanced Enterprise Services.其中Layer2 Base 和LAN Base软件包只针对二层交换机,从IP Base开始针对多层交换机(MLS Switches) .出厂的交换机缺省情况下二层加载了Layer2 Base的软件包,多层加载了IP Base的软件包。

下面介绍各个软件包所具体包含的特性集:

LAYER2 BASE : 用于接入层交换机,通常为29xx. 特性集 : Bridging, spanning-tree (802.1D), 802.1X, etherchannel (802.3ad), Rapid Spanning-Tree (802.1s/w), port-security, smartports, SSHv2.

LAN BASE : 用于需要配置QoS和过滤的接入层交换机,通常为29xx. 特性集: Cisco AutoQos, Cisco AutoSecure, 802.1X, Time Based ACL, Port based ACL, advanced QoS ( Layer 2 to 4 classification, ingress policing, ingress rate limiting, classification DSCP)。

IP BASE: 用于小型局域网路由,硬件切换等交换机,通常为6500 特性集: Static routing, RIP, Stub EIGRP, basic PIM, HSRP, VRRP, GRE tunnels.

IP SERVICES : 用于多层交换的局域网或者广域网,需要高可用性等,通常为6500 特性集: IP routing EIGRP, OSPF, PIM, BGP, PBR, GLBP, HSRP, VRRP, Redundant PR+, Multi-VRF, WAN, NBAR.

ADVANCED IP SERVICES: 用于多层交换的ISP,园区广域网等,通常为6500 特性集: IS-IS, MPLS, L2VPN, L3VPN, IPv6.

ENTERPRISE SERVICES : 用于多层交换的汇聚层或者核心层,通常为6500 特性集: Appletalk routing, IPX, services IBM

ADVANCED ENTERPRISE SERVICES : 用于多层交换的汇聚层或者核心层,通常为6500 特性集: Firewall IOS, IDS . 汇总图

下面这八个针对路由器的软件包从IOS 12.3T版本开始,2005年八月放出: IP Base, IP Voice, Advanced Security, SP Services, Advanced IP Services, Enterprise Base, Enterprise Services和Advanced Enterprise Services.缺省出厂的路由器都加载的是IP BASE软件包. 下面是各个软件包所包含的具体特性集 :

IP BASE : 路由器的出厂配置. 特性集 : DSL, Ethernet switching, inter-vlan 802.1q routing, vlans trunking.

IP VOICE : 用于语音/电话架构的网络. 特性集 : Voice modules interfaces, H.323, MGCP, SIP, SRST (Survivable Remote Site Telephony), Call Manager Express.

ADVANCED SECURITY: 用于安全架构的网络,VPN网络. 特性集: Firewall IOS (SDM, CSM), IP flow security, VoIP, intrusion detection, Easy VPN client/server.

SP SERVICES : 用于ISP网络,园区网,城域网. 特性集: Data and voice flow connectivity on IP and ATM, MPLS labels switching.

ADVANCED IP SERVICES : 用于DSL ISP,Cable ISP或者IPv6网络. 特性集: Security and data/voice VPN, IPv6 connectivity.

ENTERPRISE BASE : 用于和老的需要IPX等协议的网络进行路由. 特性集: multi-protocols IP, Appletalk, Novell, IPX.

ENTERPRISE SERVICES : 用于需要古老协议的网络和ISP网络. 特性集: Voice over ATM 和IBM services (Enterprise Base).

ADVANCED ENTERPRISE SERVICES : 用于多协议网络,城域网,VPN,VOIP等. 特性集: Data/voice multi-protocols on IP, Appletalk, Novell, DECnet, security, VPN, MPLS labels switching, Ipv6 networks. 汇总图:

常这些软件包可以通过两种方式来区分,一种是IOS的文件名,另一种是销售商的产品号(product code) 下面是一个2800系列路由器的命名示例:

软件包名 文件名 产品号

IP Base C2800-ipbase-mz S28NIPB-12308T IP Voice C2800-ipvoice-mz S28NIPV-12308T Enterprise Base C2800-entbase-mz S28NEB-12308T Advanced Security C2800-advsecurityk9-mz S28NASK9-12308T

SP Services C2800-spservicesk9-mz S28NSPSK9-12308T Advanced IP Services C2800-advipservicesk9-mz S28NAISK9-12308T Enterprise Services C2800-entservicesk9-mz S28NESK9-12308T Advanced Enterprise Services C2800-adventerprisek9-mz S28NAESK9-12308T

一个2800 IP Voice的软件包价格450欧,而一个Advanced Enterprise Services的软件包则价值2000欧... 7200/7300系列路由器软件包

7200/7300系列路由器软件包7200/7300系列路由器的软件包和前面800到3800系列的软件包主要有以下三个不同:

IP Base软件包增加了SSH特性支持 package

Advanced Enterprise Services软件包增加了SNA switching特性支持

Advanced IP Services 增加了Lawful Intercept特性支持。Lawful Intercept (LI)指的是可以满足政府对路由器数据进行侦听的需要. 而这样的软件包也价格不菲,7200的相应软件包价值9000欧. 汇总图(适用于IOS 12.4(2)T):
