ASK:难道2948G-L3没有第二层功能只有第三层功能?????怎么48个口之间不能互相看到????两台电脑随便连两个口给相同网段的IP不能ping通,重新传了一个IOS也还是这样,后来有拿来一个2948G-L3也是这样,才觉得可能不对,请问到底是怎么回事????型号中的G应该是企业版的意思吧,企业版的应该是带
路由功能的吧,L3是第三层的意思吧。是不是真的没有交换功能???
FW:L3就是说第三层交换,当然有第二层的,交换机本来就是工作在第二层的嘛!至于互相不能ping通,恕我才疏,不明白。型号中的G应该是表明该机是带GBIC扩展接口的并非企业版的都带
路由功能,例如ws-c2924-xl-en就是企业的(增加了VLAN、ISL),en 才是企业的意思。中高端的一般都是企业用的,所以不用标识。
FW:做个bridge group试试看
route ip
ASK:ci
SCo的到底有哪些型号的交换机支持MLS???
FW:
你是说多层交换吗?
5000的3代引擎,6000,3550,2926G
FW:在6000的MSFC上做MLS

IEs router
Catalyst 5000 family ATM module and a router with an ATM interface if running MLS over ATM media
(Optional) Inline-rewrite capable switching modules—These switching modules have onboard hardware that maximizes IP MLS performance (this performance enhancement is also used in the Catalyst 2926G series switches). Use the show port capabilit
IEs command to determine if your hardware supports inline rewrite.
ASK:那么如果MLS中MLS-RP是外部
路由器的话什么型号的交换机能充当MLS中的交换机??
FW:6000
ASK:大家都跑题了!!!!我的问题还没解决呢!!!!!
FW:2948G-L3端口需要手工激活!
如果还不行,就做个BVI,和bridge,把所有端口放到相同bridge里
