I am working with a 4400 controller and 1020 APs and I am trying to add a new WLAN to migrate old devices onto a new security/auth. The problem that I am running into is that when the WLAN is enabled, 15 of the 20 APs start rebooting constantly with ...
I am trying to kill off some NETBIOS traffic within a VLAN with a VLAN filter map so it dosn't keep filling up my logs when it fails against the inbound ACL on the VLAN interface but it is not working as I expect it to (and my other VLAN filter maps ...
If I have two VLANs, 1 (native) and 2 (iSCSI) and I want to put inbound ACLs to restrict the traffic that gets into VLAN 2. From the perspective of VLAN 2, does my inbound ACL get evaluated for both traffic originating from VLAN 1 and going into VLAN...
I need to allow for good traffic into my vmware environment but block bad broadcast and multicast traffic from getting in. Currently I have an SVI setup to allow for the communication but it seems to allow broadcast and multicast traffic to get to my...
Since implementing QoS on a T1 link it seems that the utilization has dropped ... a lot, and I need a quick review to make sure I didn't fat-finger or do something dumb (it happens). The interface is a full T1 (private point-to-point), which should b...
There are 2 enabled SSIDs/WLANs, this will be #3. I have read that the 1020 will support upto 8 (though for radio management best practices, there will only be 3 in the end).
As a point of reference, 1000 hosts will completely saturate a 10Mb network with nothing but control traffic. Stick with /24 and route where necessary. If you go above /24 implement private-vlans to control your broadcasts. I have done work on a camp...
I think that that is what I have already done ... it is very similar to this: http://www.cisco.com/en/US/docs/switches/metro/catalyst3750m/software/release/12.2_46_se/configuration/guide/swacl.html#wp1082532vlan access-map Filter_VL4 10action dropmat...
You really want to avoid using 'ip address secondary' if possible. Make the interface into a trunk, then make your virtual subinterfaces such as fa0.1 fa0.2 fa0.3 etc and assign them an IP address. I'll post some example code in a second. My example:...
