Hello
I am sorry, I feel like this is a very basic question. But we have a somewhat confusing scenario and when I do a show ip route command, it doesn't clear things up. So I just wanted to get an understanding what it means.
For example:
SWI001#sh i...
Hello
We are having some issues with some guest access for a remote site and one thing I have noticed is that the clients don't seem to clear from the Controller>Mobility Management>Mobility Controller Clients table on the Anchor. Just wondering if t...
Doing a MIB walk for port security section on 2950 and can't find cpsifstickyenable entry (among others) - appears some part of the MIB table is missing. If I do an SNMP walk for Port Security OID (.1.3.6.1.4.1.9.9.315.1.2.1.1.15), switch doesn't inc...
Hello,We have a network of more than 1000 network devices. We introduced ssh a number of years ago. At the time we used key modulus 512. We are now implementing modulus 1024 with any new devices being installed. Yesterday we installed a switch (2960...
Hello,Can anybody advise of when CEF flushes entries in its forwarding table? Are there any commands to view that table and can timers to flush entries be influenced? I mean can I change the timer to flush the entry if the source/destination stream h...
maybe it's still helpful. i had the same issue. check the version of ssh configured on 1.1.1.1.I have two switches (2950, same IOS etc), destination switch configured with ip ssh version 2. when trying to ssh from switch one to that it gives me error...
Thank you ever so much.It is very odd. I can putty to the switch and "show ssh" gives meconnection 0 connected with version 2.0, encryption 3des-cbcOn one of the new switches it gives me:connection 0 connected with version 2.0, encryption aes256-cbcP...
Thanks Istvan,I've tested again in my test network. per-destination seems the default. It's good, it does do source/dest pair load balancing. And even on one single outgoing interface. Fair enough the CEF next hop table doesn't time out. But there mu...
Hi Istvan, oh dear, they've written a whole book on it. Looks like I had the wrong impression, I thought it had individual datastreams in it's cache (like 1.1.1.100 - 2.2.2.100), but it looks more like a routing table (dest 2.2.2.0 via x). I just wan...
Hello IstvanAha. I thought CEF was a different switching method to fast-switching. Looks like its a different process that runs before fast-switching. All I could see is that 1/20th of the CEF cache gets invalidated every minute. Is there a rule (old...
