I use sniffer 4.70.5 to capture traffic between server and client. And found so many "non-responsive station". I'm in doubt why it will prompt it. On sniffer manual,it said:"The analyzer generates the diagnosis Non-responsive station (and considers a connection broken) when the number of...

I am newbie,can u explain more detail? thanks Henry

today I already know why 2500 can ping 88.1.77.1 because proxy-arp doesn't function on serial interface. so what's the real function of proxy-arp on serial interface ? Does it work when bridge on the serial interface ? If bridge on serial interface,how ios transfer arp ? I think there isn't...

2500-s0-88.1.201.1/16------88.1.201.2/24-s1/0--2611--e0/0--88.1.77.2/24---88.1.77.1/24-f0/42-3550 I can ping from router 2500 to 88.1.77.1 even if I disable proxy-arp of 2611's s1/0. There isn't any dynamic or static routing except a default route on 3550 to 2611. I can't understand this...

I remember rs232 speed is up to 19.2 kbps,but why I can config clock rate to 128000 when I plug the 232 DCE cable to 2611's nm-8a/s? I can't understand.Is cisco's rs232 enhanced rs232 or something else ? thanks!

If mls probably adjusted itself automatically,why it display "IP Current flow mask is Destination flow" ? Does it running IP-FLOW mode internally and will not display this message for me ? thanks!

I think MLS is working.If I "show mls" or "show mls entry",it display normal. So I can't understand why it is working normal even if mls flow mask is Destination flow and my msfc2 is configured with extented ip access-list. This is my question. thanks!

I got it from cisco.com. CAT3550/CAT6000 with Sup2/MSFC2, CAT4000 with Sup3/4 uses CEF based forwarding. CAT6000 with Sup1/MSFC support MLS only CEF is a enhanced implementation of MLS. With MLS, the first packet hits the router to get routed and then subsequent flows are hardware switched...

1. Does mls running only on cat6000,cat5000 and cat4000? How to implement l3 switching on cat3550 if it doesn't support mls? 2.What's difference between mls and cef ? Cat6000 support these functions both.Will cat6000 choose which type of technology when packet come in? cef or mls? 3.In my...

In my router,there is a null router-map in interface,I don't know if there is some specify function or just somebody forget to delete it. any comments are appreciated! thanks! interface FastEthernet2/0 ip address 10.x.x.x 255.255.255.0 ip policy route-map null_policy_route speed 100 full-duplex...

somebody told me: diameter of the STP domain is defined: The maximum number of bridges between any two points of attachment of end stations. See http://www.cisco.com/warp/public/473/122.pdf for details. So my network diameter is 3. thanks everyone!

Sorry,correct answer is 3. The diameter is the number of switch ( include itself) between any two switch.

Cisco said pagp can setup etherchannel automatically . But how ? I connect two switch with 2 cable,and it can't form etherchannel. I remember dtp can form trunk if I connect two switch without config trunk manully. If I code "channel 1 mode desirable",etherchannel will establish...

thanks
